Verified Patient Reviews
He's great! I would highly recommend him! Upon arriving, it took 25 minutes for me to fill out the forms, see him, figure out my issue and leave! He's also very friendly and has a wonderful bedside manner!
I was late, hence my delayed time getting to see him. He's a pro and delightful to talk to. Very responsive.
The first time I saw this doctor, he made a few jokes that made me uncomfortable about skin cancer and such, but I thought that it might be his personality and shouldn't hold it against it. The second time I wanted to see him was a year later and when I called to make an appointment, I was transferred to another office. On the day of the appointment, I came to the office where I saw this doctor before, but he no longer worked there and they told me he's now at the new office, which is about 25 min away from the old office. I had to see the doctor because I had a rash and was leaving the next day for 16 days. When I called the new office to explain that I wasn't notified of the new office and that I'll be about 15 min late to my appointment because I had to quickly commute to the other office, I was told by the receptionist that the doctor can't wait and won't see me. I tried to explain that it was an emergency and that I waited for this appointment and that I came to the office 15 min before the appointment, they refused to see me. After this attitude, I decided that I wanted to change my doctor because I do not need a doctor who can't see a patient when it's emergency and make an exception for someone who is late by a few minutes due to the fact that the patient was not notified of the new office in the first place.
He runs a highly efficient practice and is an extremely knowledgeable professional. Very happy with all aspects of his care.
Great doctor and nice office staff.
He was very attentive and built great rapport. Really listened to what was the issue for me, also prescribed medication on trial with no co-pay.
Couldn't imagine seeing anyone other than Dr.Mizuguchi
The best doctor for hair and other dermatological issues
I absolutely love going to this office. I had stitches yesterday and I still had a good time. The Dr. and the staff are so down to earth that its such a pleasure talking with them. They give samples and tell you great over the counter products. They don't try to sell or push products. I Love going here!!
dr mizuguchi as very knowledgeable and seemed extremely up-to-date on up and coming research and new developments.
It was good
Very easy to talk to. Very knowledgeable.
He was very pleasant and easy to talk to. He knew his stuff and didn't reccomend a bunch of work to be done. I felt like he was honest with his findings and had my health as his primary concern.
I always enjoy my visits with Dr. Mizuguichi. He has a welcoming personality and treats his patients with the utmost respect and courtesy. Dr. Mizuguichi keeps up with new treatment modalities and shares this information with his patients. I trust his medical judgement.
This was my first visit with the doctor, he was very pleasant and saw me right away. I have not began taking the new medications he suggested but this review is strictly based on this visit and not the treatment outcomes.
Dr. Mizuguchi was very professional, and also had a delightful bedside manner. He was very reassuring, thorough and I did not have to wait an hour to see him! Will definitely make him my permanent skin doc and would recommend him highly.
He's charming, funny, smart and put me at ease! I would highly recommend him. There are very few doctors out there quite like him.
Professional courteous and friendly
Office staff on the phone and in person are wonderful. The doctor and his nursing staff are so quick and see you on time and are great.
Very fast -- a bit too fast, especially for my first-ever skin screening -- but nice & professional. Good offices.
Excellent and knowledgeable doctor. I've been a patient for several years and would highly recommend.
He's extremely helpful and knowledgeable. He goes the extra mile to make sure his patients are getting good prices on prescriptions. He's the man!
Dr. Mizuguchi was fantastic- I was seen right away and didn't feel rushed at all. He was personable, friendly, and took time to explain what I needed to know. I felt like he really listened to my concerns.
Full of information and really a pleasant person. Had me in and out quickly with everything I needed
I could hear the doctor making jokes outside the door for quite some time while I waited in the room. He was trying to have a zany personality I guess, but I had a serious issue which I felt he was not taking seriously, and he was not listening closely to what I was saying. I was telling him about my psoriasis history, and he interjected "how do you know it's not eczema??" He then prescribed an ointment for eczema, which was not what I needed. I didn't feel an ounce of trust toward this doctor. I won't be back.
Professional, personable, of good humor, informative.
Knowledgeable and professional. Very short wait time
Very friendly, he makes his patient very comfortable.
Very pleasant and knowledgeable; answered all my questions completely and thoroughly. His assistant Lisa was also very pleasant and professional. Definitely my 'go-to' doctor!
Dr. Mizuguchi is the best. Extremely knowledgeable, kind and helpful.
Excellent, as usual
Just the best!
He was great, but scattered. His staff had me waiting, first to see him, and then again afterwards because they weren't sure what he had prescribed. It might have just been pre-holiday fog, but if it happens again I might look elsewhere.
Very thorough and extremely personable - makes every visit an absolute pleasure!
Wonderful physician makes you feel very comfortable and is knowledgeable
Dr. Mizaguchi professionalism, skill, and cheerful demeanor, not to mention his excellent memory of past issues and treatments, provides a comforting, unparalleled experience.
Love him! Fast and informative, confident in his suggestions. Been seeing him for yearsss and refer to all my friends and family
He's a great doctor with a great manner.
my visits with Dr. Mizuguchi are always quick and productive! He's personable,professional and easy with injections.
Really liked this doctor - will be back!
Great energy, sound advice, highly recommended!
Dr. Mizuguchi is very knowledgeable and approachable. He answers all of your questions.
Very nice office: spacious reception area and friendly reseptionsts. I wait around 10 minutes before I was seen by doctor. DR. Was highly professional, he did not rush and asked all my questions. Highly recommend!
Only waited a few minutes to meet with Dr. Mizuguchi. He is fantastic - fast, knowledgeable and easy to speak with. I highly recommend him.
I've seen Dr. Mizuguchi for 8 years. He is extremely attentive and relatively aggressive with treatment (which is what I was looking for). He is knowledgeable and aware of up and coming treatments and dermatological trends. I have recommended him to many people and will continue to do so. I've had nothing but great results with him.
Friendly and caring with a sense of humor. Highly recommend.
I have been seeing Dr. Mizuguchi for years. He is always knowledgeable and friendly. I spent only a short time in the waiting room.
Been seeing Dr Mizuguchi for years. He's great, knows his stuff. Referred him to many of my friends and colleagues.
hear my situation and decided to be way of treatment quickly. Good doctor. Recommend !
Awesome as usual
Dr. Mizuguchi is jovial, very friendly, frank, and thorough. He uses his time wisely, answers all of your questions, and is able to have a good conversation while still concentrating on the task at hand.
Dr Mizuguchi was very pleasant with an excellent bedside manner, something I rarely see these days. He listened to my concerns and explained things in a clear manner. He was also proactive in asking about other potential concerns I might have. I just waited about 5 minutes past my appointment time.
Dr Mizuguchi is great! He is always fast, but still thorough.
He's very personable and friendly. He is also fast and efficient. He wasted no time but made me feel that I got all of my questions answered.
I just adore Mizuguchi ! Both my husband and i have seen him for years. He is very smart, funny and spot on.
He's a cool doctor great personality I only have him 4 stars because he fussed me out about waiting so long to see him..but overall I would recommend him to anyone
He was very funny and knew right away what to do for me. My itchy scalp has never been more manageable.
I went to receive some prescription topical medicine for some breakouts. He asked if I wanted a cortisone injection in a larger pimple, and I said yes. It's a pretty routine injection, and I've gotten them before without any issue. The day after my appointment, I noticed a bruise where he had injected the cortisone. After a month the discoloration is still there as well as some puckering. I have called to try an make another appointment and have yet to hear back.
Dr. Mizuguchi is just the best dermotologist i've ever had!
I have been experiencing a very specific issue and Dr. Mizuguchi is the third doctor I've seen trying to get to the bottom of it and he's honestly the first doctor that has really helped. I'm very happy with him and his offices.
Wonderful experience - Highly Recommend
Never disappointing .
He is very personable and highly professional. An excellent therapeutic experience. He's great! I tell everyone I know about him.
It was a surprisingly good experience. It's become the norm (frustratingly so) to be made to wait for 30 min, 60 min, even 90 min, even when you have an appointment. This entire experience was a dramatic contrast and in a word--it was excellent. The receptionist was very nice as well as friendly and there was only a 20 minute wait. Dr. Mizuguchi was first rate--warm, friendly, and critically, his expertise was clearly evident and gave me full confidence in his comments (another aspect one doesn't always feel after leaving a doctor's office). I have nothing but praise for this doctor and the functioning of the entire office!
I had a great visit with Dr. Mizugushi. He answered all of my questions and was very friendly.
Everything was great! He made the time to talk to me and answer my questions, and that's super important.
He's the best. Always with a sense of humor and really well informed on latest trends.
Excellent as usual
In addition to conducting procedure, Dr. Mizuguchi answered all of my questions!
very personable, clear and considerate. knew right away how to address my problem and was very considerate!
He's friendly and responsive
QUICK! I didn't even have time to fill in my new patient paperwork before getting called in to see the dr. Love that!
Efficient, knows what he is talkiong about. I like him
Always professional, friendly and quick.
He's a great doctor. Knowledgable, trustworthy and extremely personable.
He's a nice guy, and I think he means well, but my appointment was like a blur. He literally ran in and out of the exam room like 3 different times, he was talking a mile a minute, and didn't give me a diagnosis (or really any kind of idea). Which is fine, sometimes it takes a few visits to find out what's going on but he didn't even exam me. I would not recommend him. I saw another derm the next day and I was examed & diagnosed on the spot.
It's nearly impossible to find a very good dermatologist, but this is one. Very thorough and personable, absolutely knows his stuff. My favorite doctor.
Dr. Mizuguchi is easy to speak with, likable and informative. I never feel rushed with him. It is also to get an appointment. I would recommend him to anyone looking for a well informed dematologist.
He was in a rush and kind of wanted me to leave his office so he can be somewhere else. Not so happy with how he handled my questions.
Very friendly and nice. Front Desk was also pleasant to deal with. Was a not a long wait in the waiting room. Office is a nice short walk from metro.
Excellent doctor, great bed side manner and thoughtful! Highly recommended.
Great doc. Personable and knowledgable. Good with medical data and statistics. Nice staff.
As always, great appointment! Was seen right away!
It was extraordinary. Dr. Mizuguchi was very professional yet also very polite, positive. He immediately puts the patient at ease and takes time to answer all questions. I'd easily go back to him and highly recommend him. Good staff too, particularly nurse, Liza.
I had to wait a bit to get checked in as a new patient because they were short-staffed. However everyone was very pleasant. Dr. Mizuguchi was great - bright, cheery, and very comprehensive in answering all of my questions, looking at the products I brought in to make sure they were okay for me to use, thorough with his explanations and concerns and what my next steps should be. My new favorite doctor!
Frankly, one of the friendliest and engaging doctors I've come across. Staff was courteous and organized.
Dr. Mizuguchi is friendly and efficient. He makes you feel comfortable while addressing your issue. I've gone to him numerous times over the past few years and highly recommend him.
very nice, very informative and thorough
Dr Mizuguchi was great! Very friendly, personable and knowledgable but best of all he helped me uncover the cause of my recent hair loss. I would definitely recommend him.
Fantastic person to be around who loves his job and respects his patients.
I always have a good experience with this doctor.
Excellent visit, as always. Recommended highly.
He was very thorough, pleasant and efficient.
He's super energetic and seems to know his stuff. However, I always feel really rushed when I'm there and I have to ask a ton of questions in order to get any information on my condition. I would recommend him always but if you need someone who really sits and breaks it down for you he might not be your best bet. Just keep asking questions!
Dr. Mizuguchi is excellent !!!
Very warm, thoughtful, incisive, articulate and generous with his knowledge and time.
I came to Dr. Mizuguchi with only health concerns, not cosmetic concerns, for an annual check-up. He was very thoughtful and knowledgeable, and I will be seeing him annually going forward. I appreciate the information he shared with me, and that he addressed all of my concerns and issues. Specialists like Dr. Mizuguchi are essential for long-term wellbeing and peace of mind.
it was incredible, Dr. always gives a prescription coupon for the products he suggests. The office staff is very quick. You never wait.
Dr. Mizuguchi was extremely personable and made me feel very comfortable. He listened to my description of the problem, went through a range of possibilities as to what might be causing it, and left me feeling confident in the treatment plan. I also really appreciate that he threw in some additional information on sun protection (unrelated to the reason I was there) that he thought I might find helpful. I'd definitely recommend him to anyone looking for a dermatologist.
He listened to my problem well, and paid attention to my history with the issue that i am having. he subscribed some easy home remedies along with a new medication which he properly and patiently explained to me. He also has a great sence of humor and makes the patient feels relaxed and at ease. I would definitely return to Dr. Richard in future. I am yet to start using my new prescribed medication by him, hence, not sure if that would be effective for me, but am hoping it will work.
He just didn't do a great job with my skin examination. I had to point the moles out for him and he didn't put much effort into looking at the others. Gave decent advice.
Short wait time, doctor was obviously very knowledgable and also didn't patronize me for bringing up my webmd-based inquiries.
He had a terrible bedside manner and he told me I needed an ointment for dry skin around my lips because, and I quote, " You don't want to look ugly do you?". He was one of the most insensitive and offensive doctors I've ever experienced.
I went for a simply visit for preliminary hair loss-- staff was professional and relatively quick. Dr Mizuguchi was very personable and answered all my questions. The visit took all of 20 minutes--but, frankly, given the circumstances that was all that was needed. He immediately emailed my prescriptions to the pharmacists and let me know that he would be readily available when prescriptions were required. Too soon to say much more, but I was very satisfied with the service. Based on this, I would recommend him.
He cured my wart when another dermatologist didn't.
Enthusiastic, confident, and hilarious doctor. Makes you feel comfortable and is very reassuring. Many thanks! :)
My family and I have been seeing Dr. Miziguchi for several years for everything from eczema to breakouts to mole removals. He's always been personable and down-to-earth in answering any questions we may have. I highly recommend him!
Dr. Mizuguchi is very easy and always in a great mood when I see him. Very knowledgeable and I highly recommend him!
Pleasant bedside manner other than feeling that I was a bit rushed.
He's simply awesome! Great bedside manner, personable and thoughtful in his approach. I've been a patient for a few years and highly recommend him to friends and family.
The receptionists and the nurse were very pleasant , efficient and friendly. Dr. Mizuguchi was very attentive to what I was telling him and seems like he cared about me as his patient. I very highly recommend him and I am very happy I found him in my Internet research for dermatologists!!! Thank you Dr. Mizuguchi.
Very easy to get along with, thorough, talked through everything with me in detail, didn't seem impatient or rushed, but was still very efficient.
He is one of the best Doctor I have seen!!
Other than the wait, it was as good a doctors appointment one could have.
I love that Dr. Mizuguchi is super friendly and informative, and he takes time to chat with you for a minute. He also makes sure that he gives me a quick once over to be sure that nothing looks suspicious, even when I'm not there for a mole-check. I feel like I'm in good hands with Dr. Mizuguchi!
Does/Knows his job well. Very comfortable environment.
As always, clinically excellent, personable And fast...
Dr. Miuguchi is a very hyper doctor who didn't listen and tried to push a mole exam instead of listening to the actual reason for my visit. Finally listened and did a hasty job which left a scar. Not sure how anyone would give this doctor more than 2 stars unless they had a dynamite mole exam from him.
As always, I go away happy to have found such a capable physician and wonderful person.
Diagnosed my problem right away,very easy to talk to,answered all my questions. Very nice atmosphere.
Super nice, efficient, thorough. Went for acne, was able to get a few prescriptions that helped!
Loved chatting with Dr. Mizuguchi at my appointment this morning. He was very easy to talk to, and was both efficient and thorough.
Really knowledgeable and humorous guy. The visit was a breeze. Quick diagnosis, clear treatment steps. Highly recommend.
He was nice enough, but pretty much blew off all my questions and concerns. He seemed to have his own agenda for what to speak with me about and I was shuttled in and out promptly, with as mentioned, no true time to discuss any of my questions.
I've seen Dr. Mizuguchi several times and have always found him to be courteous, knowledgeable, professional and personable.
It's always a pleasure.
Very nice, personable and professional doctor
He is such an amazing doctor! He makes it easy to "go see a doctor".
Excellent staff, and a very friendly doctor that explains himself well.
It's a pleasure to see Dr. Mizuguchi: he is extremely personable and makes every visit painless.
He's funny and normal. I like going to him
Nice guy with personable manner who was inquisitive about my background and who went to some lengths to find common ground with me. Frank discussion about my treatment options and he wasn't pushy about any of them. It made me feel like the choice really was mine and I liked that.
He was amazing, very knowledgeable and extremely helpful. Would highly recommend!
Very friendly and helpful!
I found Dr. Mizuguchi to be highly personable and enjoyed his demeanor much more than other Dermatologists I've visited previously. I highly recommend him.
He was very personable and easy to talk to.
Awesome doctor! Very personable and makes patient feel very comfortable. Efficient and thorough!!
Dr Mizuguchi is pheonominal! I've been to many dermotologists in my years of troubled skin - he gives great advice, is quick and thorough and not to mention personable and makes you feel comfrotable!
Use the word "retarded" to describe himself, would think that a doctor would use more appropriate language. Wait was forever, booked way too many people. Would not recommend and will not go back
I would definitely come to him again. Knowledgable and great attitude
I've seen Dr. Mizuguchi for about 4-5 years now. He is on the cutting edge of dermatology and knows exactly what he's talking about. He's also funny. I've recommended many people to him and will continue to do so.
I loved it! He was so fast and answered my questions. He always wanted to make sure i understood what he was explaining. i just wish i was ready with more questions. another note, the staff at his office are as fast, courteous and efficient as he is.
He is great!
Doctor was great! Very comfortable experience, great bedside manner. Did have to wait a bit though to be seen.
Helpful, friendly, and informative. Highly recommended.
Cheerful, professional, knowledgeable. I will continue to see this Dermatologist.
Always provides great explanations of the prescriptions he provides and explains things in an easy to understand way. Great doc!
Very knowledgeable, which is what one would expect from a MD. I find that what makes Dr. Mizuguchi exceptional is that he listens and seems earnestly concerned. Wonderful bedside manner, efficient without making the patient feel rushed.
Dr Mizuguchi is awesome, but the wait in the office was a bit of a pain.
Dr. Mizuguchi was super personal and friendly. He was pleasant to talk to and helped me with everything as soon as I visited him. I only had to wait a little bit because I was filling out forms. After I was done, I only waited for 5 minutes. I would highly recommend him!
Efficient and easy to talk to.
Although the wait time left something to be desired... the visit was nothing less than pleasant and made me glad I waited all that time. He listens carefully and explains things thoroughly. I'm very glad I found this doctor, I will be back for sure. It's even better the office is only 2 blocks from my job!
Great attitude. Personable. Smart. What every doctor should be, but isn't.
He's fantastic! Highly recommend him - very knowledgable, takes timeto answer questions, personable.
Visit with Dr. Mizuguchi was a pleasant experience. Hardly had to wait to meet with him. As soon as he came in he was extremely friendly and conversational (which I find very reassuring with medical professionals) and was able to clearly explain my issues to me. One thing I do need to say is I feel as though I was slightly rushed. I'm sure it had more to do with his bubbly and energetic personality, however I was so caught up in the conversation I did forget to ask one question. Otherwise he was a lovely man to meet.
Dr. Mizuguchi was very knowledgeable and up-to-date with the latest drugs. He send prescriptions directly to your pharmacy online so it will be ready 30 minutes later!
Dr. Mizuguchi was very friendly and knowledgeable and saw me right away. I would definitely recommend him to others.
Very friendly, professional and helpful. I will definitely see him again.
He took more time than most Dermatologists to explain his diagnoses/prescription regimen than most, and showed interest in what I had tried before that didn't work so we could try something new. Also, seemed like a really nice guy.
He is a friendly and very good Dermatologist, I feel very comfortable with him. He understands the unappealing bouts with cystic acne.
we communicated well and that counts!
Friendly, knowledgeable, personable.
I really wasn't happy with my visit at all, aside from the fact that he got me halfway to an acne treatment that works (a topical cream). He was rushed, giggly and ended up offending me in the end, in relation to a conversation we had. I will never go back.
He had excellent bedside manner and put me at ease. My only complaint would be that my problem might have been a really simple one to diagnose, but I would have liked him to have at least go through the gesture of examining instead of only relying on what the nurse had said and saying this is what you have before checking the symptoms himself.
He's so friendly and professional doctor.
Great Dr. very kind and open! Knowledgable and willing to awnser questions!
I liked him a lot - very straightforward and professional.
Very knowledgeable, professional, easy to talk to. He was able to tell me right away things that other dermatologists couldn't. His staff are friendly. Highly highly recommended.
This Guy just ROCKS!!!!!
Dr. Mizuguchi explained thoroughly to my questions.
Very pleasant and amiable doctor. He saw me right away.
Fantastic! Since my regular doctor wasn't available for several months, I did some research and found Dr. Richard for a quick last minute appointment. I'm so glad I did! He is so amazingly personable, informative, and professional. He provided me extra insight into my condition and he was honest about my options for treatment. He didn't try to push any expensive procedures. He listened to my needs and concerns and tailor made his recommendations for my medication accordingly. I may have found a new dermatologist!!
Professional, passionate, great energy. Clearly cares about what he's doing and listens to his patients. Highly recommended.
He was great. Very professional and to-the-point, but also made time for some jokes and to listen to my concerns. The entire practice actually seemed very well run.
Quick and to the point !
He had a great attitude and high energy. He was honest and helpful, and i only waited a few minutes to see him!
Great doc. Quick, easy and knowledgeable.
Great doctor, very easy to work with and quick treatment.
Knowledgeable. Concerned. Professional.
It was a great visit. Comfortable and efficient. Thanks!
I went in for a skin screening, and my experiences with other Drs has been that they take their time and are thorough to consider if you have any risk of cancerous moles. That's the whole point of the appointment, right? Dr. Mizuguchi was so quick and brief, I was left wondering if I was supposed to wait in the examination room for him to come back or not.
Very friendly & hyper/chipper. Knowledgeable in his field of specialty. The medication her prescribed resulted in an improvement in my condition within a few days. The visit was very quick, only spoke with the doctor for less than ten minutes.
The visit was quick and painless. wait time was next to nothing! the dr. was great attentive and very informative.
He listened to my concerns, didn't to much to verify them but prescribed me things that were a temporary fix. I don't have a lot of time for return appointments, but overall I was content - although I do wish that my self-diagnosis would have been taken with a larger grain of salt and that he would have ran some tests or taken a better look at my scalp.
He said he read on a blog that a lot of people were getting a similar skin itchiness. A doctor who basis his diagnosis on a blog isn't for me.
He seems to be a really nice person...I felt he should have looked into my condition in more detail...but, if things cure in next few days...what more do I want...
Nice office, helpful staff. Efficient. Dr. Mizuguchi was very helpful. Good man.
Very professional staff, nice office and great doctor. Most pleasant experience I have had with a drs office in NYC
Very professional, office is well organized.
Dr Mizuguchi detected the problem right away. He was friendly without being invasive. Very knowledgable and efficient. We were out 10 minutes. Strongly recommend
