Do not waste your time with this doctor. He was my 2nd opinion for my daughter's skin condition. Two weeks after the appointment I called to ask about the treatment plan because the issue has not gone away completely; recurring. He had no response for me. He asked me to bring her back in to look at it, even though he had already seen it. If there are not any other treatment options, why would I bring her in for him to look at it again, especially when he already said there were not any tests to run. Very disappointed with service and his bedside manner. My daughter doesn't even want to go back to see him!!!
Dr Porres was thorough and proficient. He spent time with me and gave me excellent advice.
A first-class physician. Highly recommend.
The office staff were very friendly and accommodating. Dr. Porres was funny and put my son at ease. The issue was resolved quickly and professionally. There was a long wait, but I can understand why, considering Dr. Porres' manner with patients. Overall, it was a great experience.
Very nice and offers detailed explanations without seeming rushed.
Don't look elsewhere!
Excellent doctor, great diagnostic ability and treatment recommendations.
Very friendly, knowledgeable, and through.
Great bedside manner, good listener. Works through the problem with the patient.
Really liked the appointment. MD PHD DR. Porres listened and was very pleasant and professional. .Going back.
He was very good, but I was waiting around 1 hour to see him.
Dr. Porres is fantastic. He's very friendly and has great bedside manner. He also emphasizes educating his patients instead of just looking and prescribing something which I always appreciate. The office staff is also very friendly. I'll definitely be coming back here from now on.
Dr. Porres is very personable, kind and down to earth. He took plenty of time with me and explained everything to me very clearly. He also gave me some tips for treating my dry skin. This was my first visit with Dr. Porres and I am quite impressed. His office staff was very friendly, efficient and helpful. I certainly would recommend him to anyone.
Highly knowledgeable with a good bedside manner. I would definitely recommend Dr. Porres.
Very friendly and helpful. Gave me all the information and explained it in an easy to follow way.
Excellent, knowledgeable doctor. Fantastic.
Very personable & professional.
Dr. Porres is an excellent doctor. He was very patient and meticulous in listening to my concerns, and suggested many different forms of treatment and applications that wouldn't inhibit my day to day activities. The only downside to the visit was the long waiting period. Other then that, he's an awesome professional!
He was very calm and positive. He was attentive and spoke to me like a person, not a number; made some small jokes to put me at ease but was very professional. I needed a procedure that I believe many people would be nervous about and he was quick and gentle and explained each step. Before I knew it he was done with the part that made me anxious and thats a good doc in my book.
Dr. Porres really focuses on each patient, he doesn't feel distracted or rushed when he's working with you and makes you feel comfortable talking to him about skin issues. Between that and his ability to handle minor skin issues right there in the office, quickly and rather painlessly, he's been my favorite dermatologist so far. :)
It was a great experience , doctor porres is excellent took his time to discuss my concern.well done
Dr Porres is kind, patient and fully proficient.
This Dr is professional and caring. I value his judgment and he has done well treating my whole family.
Incredible Doctor. Extremely attentive, caring and professional. Highly recommend.
I was extremely uncomfortable and for very good reason.
Dr Porres was an incredibly thoughtful and thorough doctor. He listened to my problem and addressed my concerns. He was very careful to explain side effects of medications and give advice on how to remedy these issues.
Years ago, I saw a dermatologist who was great, he took the time to discuss each issue and was never rushed. I moved and have since went to other dermatologist, but none were the same. Every one of them was a cattle call, they pushed you in and out the door asap, you only got a few minutes with the doctor and spent most of it with their assistant. I never lasted at any of those dermatologists. That was until I met Dr. Porres. I was seen quickly, it seems like it is just him and the receptionist. Dr. Porres saw me and spent almost an hour discussing my issue and looking me over, he was extraordinarily friendly, educational, and money seemed to be the last thing he was worried about. I would definitely recommend him, especially for those who are sick of the cattle call. He has somewhat of an old school feel to him and his office matches it, but don't let the older looking equipment and sparse waiting room fool you, he's top notch.
The doctor himself was great, and super informative. It was the office staff there that was terrible. Both of the receptionists that were there were SO rude. The weather was very bad this morning, so I was running about 5 minutes behind. My appointment was at 11:30, so I called around 11:15 to tell them that there was an accident on the highway and I was running a little bit behind. The receptionist that I spoke to on the phone didn't know who I was or why I was calling, she didn't have any record that I made an appointment. Finally she finds me and says that I can reschedule because they go to lunch at 11:30 and if I'm late no one will be there. I said I would only be 5 minutes late and she said that if I was any more than 5 minutes late no one would be there. Finally I get there at 11:35 and they had such an attitude. It's a Saturday and I was the only patient there, and they had me wait until noon to go in to see the doctor. When I inquired, she snapped at me and said that I was 30 minutes late and that it was my fault. Not sure if I'll be going back based on that.
I expected that the doctor would tell me what needs to be done rather than asking me what I want to get done. It was a strange visit.
First visit. Appointment was on time. Dr. Porres was very efficient & extremely thorough,for anyone new to the area and/or looking for a new dermatologist I would highly suggest Dr. Porres, getting apointment is easy and fast.
Excellent, compassionate physician; very thorough, honest and up front with treatment plan.
Excellent, as usual. Discussed a couple of problems, he listened to my concerns, then offered some courses of action while telling the pros and cons of each. I chose one, that would solve my dermatology problems.
It was wonderful. Dr. Porres has a wonderful sense of humor and was very easy to talk to.
Dr Porres is patient and kind. Compared with my last dermatologist, he took time to explain what may cause my illness and gave me a thorough analysis of the situation. Appreciated!
Dr. Porres goes beyond looking at lab results. His exam and evaluation was very thoughtful. He did not overmedicate at all. Great doctor.
Made the appointment because of some specific skin issues, plus wanted an annual skin check. Due to work suddenly getting very busy the last two weeks, I had to change this appointment three times before I could finally make it in, but everyone was quite accommodating about that. Received recommendations for the two skin issues I have, and what I particularly liked was rather than try to sell me some expensive skin cream that may be associated with a dermatologists office, Dr. Porres gave me a prescription for one problem (called it in to the pharmacy I use, so that was very efficient), and for the other simply said to use a hydrocortisone cream two or three times a day...and noted that the 'least expensive brand would be fine, as they are all the same". He also found one suspicious spot, gave me specific instructions on a topical to use on it, and told me that if I didn't see some improvement in two weeks, to be sure to come back in. Plus he asked if I checked the bottom of my feet during a self skin check. I do not...had never thought of it. so he said to be sure to do it, as we don't want any surprises to show up.
Excellent doctor. Spent a lot of time with me. Highly recommend.
Good doctor. Didn't want to make money out of my issue which he said could be left as it was, no need to deal with it at all.
Very professional, personable and gets right to work. Appointments last no longer than they need to. He is prudent but also not afraid to be aggressive with treatment when needed.
Great guy and better doctor............
My first impression of Dr.Porres is very positive. I would recommend him to anyone who has dermatologic problems.
He is very polite and indeed professional.
Great doctor. Have been to numerous dermatologist's offices and Dr. Porres has been the only who has taken the time to explain and go over things. Usually the waiting time is longer than the time spend with the doctor (with previous dermatologists) but not the case with Dr. Porres. I would deff. recommend him to anyone who seeks a dermatologist that will take the time to explain the problem, the possible causes, and the treatment.
It was overall good. I just didn't like how he wanted me to come back so soon when I don't feel that it is necessary for me to come back so quick. Other than that, he's a great dermatologist.
Dr. Porres' bedside manner wasn't horrible, but he did make some strange comments about my ethnicity that was borderline offensive, I'm Asian. I've gone to him a few times and feel that he has an old school approach.
They did not have a record of my appointment, which was frustrating because I had to wait an hour (and had confirmation of the appointment to verify the time). Dr. Porres was great once I finally saw him.
Very professional. Excellent.
Dr. Porres will make you see him every month. After couple visits, he will push products from his office. Above all the products are outrageous priced. Found the same products at other places for less than half. He is more about business than your problem.
Dr. Torres takes the time to explain things thoroughly and positively.
Horrible bedside manner. He is all about getting you to keep coming back so he can bill insurance and in his words "pay for his kids to go to school." Totally unprofessional. Will not be going back.
I waited longer than expected, but thankfully I wasn't in a hurry. Dr. Porres was kind and friendly and seemed very knowledgeable. He didn't rush me at all and made sure he answered all of my questions.
He is the nicest doc I have been too. Went over a course of treatment. All of my questions answered.
He was very nice and professional.
His staff was courteous and welcoming. I was looking for a new dermatologist and I'm happy I found Dr. Porres. I didn't feel rushed, he took time to explain and I did not have to wait long to be seen. I'll be back!
I thought that the wait time was a good wait, not too long and as soon I was called up I explained my condition. He has a good bedside manner, very nice, sympathetic and understandable.
He was great. He took the time to listen to my issues, and prescribed something that actually FIXED the problem, not just the symptoms (like my old doctor).
He was wonderful! He gave me many options for my hair and skin issues. He warned me for any possible side effects of the medication and made sure I was comfortable with it. I also like that they directly sent my prescription to my pharmacy!
Overall outstanding doctor
The diagnoses, the doctors approach and the treatment was not convincing....
I went for a skin check it was so impressed by the way that dr porres instructwd me on how to do my own skin check. He of course checked me out but also gave me very good detailed instructions on how to do it every month for myself. I would highly recommend a visit with Dr Porres simply for his expertise, sense of humor, and expedient delivery of services.
He is quite good at explaining my condition and the treatment plan.
Great visit, great doctor. He is very knowledgeable but laid back at the same time. He was honest about my options for treatment but was absolutely not pushy with prescriptions or other treatments. This is my new dermatologist.
Wonderful bedside manner; he took time to listen, explained his diagnosis, and asked if I had any additional questions.
He was great! Very friendly and sweet, and reassuring about my condition. I will definitely go to him the next time I need a dermatologist.
So glad to have found Dr. Porres. For the first time I felt comfortable talking to another person. Not your typical high and mighty, to smart, to quick, type of doctor. Dr. Porres listened to all of my issues while giving me feed back.
Dr. Porres was extremely professional and took the time to explain the procedure that I needed. I would certainly return for any other dermatology procedure I may need in the future.
Doctor Porres was very friendly and knowledgable. He eased my concerns and was very comforting. I would recommend him to anyone that needs a dermatologist.
Very professional! Determined my condition very quickly and wired my prescription to my pharmacy right away. I was in and out in less than 20 minutes.
Dr. Porres took time to answer all of my questions and talk with me about any issues that I had. I look forward to using him as my dermatologist moving forward. He is terrific.
He seemed to try to push for a follow up appointment which I felt unnecessary. He didnt provide detailed explanations to my concerns. He suggested to give me a medicine, after he opened the package to 'show me how to use it' I found out it costs 45$.
Dr. Porres is very professional and presents medical information in a clear and honest way. I was left with the impression that he's a "no nonsense" kind of doctor and very much appreciated his scientific way of making "measured" statements. He spent a lot of time with me and patiently answered my (many) questions. He was also very personable, easy-going and down-to-earth, didn't give off a snooty vibe at all (like many other doctors I've met). Overall, I trusted his judgement and advice, and would definitely go back. Great doctor! Would highly recommend him!
Dr Porres was very friendly and informative. He took the time to teach me some dermatology so that I would better understand my skin. In the end, he was happy to provide me with some simple prescriptions, but was clear that he did not recommend more aggressive treatment. I always appreciate it when a doctor does not push me to purchase services that I don't need simply for the money. Dr Porres is one of the good ones.
He seemed like a nice man with a professional approach. He explained an issue that several doctors have seen and given questionable advice. He gave me the most sensible explanation and advice to date.
He is an excellent doctor. I feel a lot more informed after todays visit and a LOT less afraid of what we need to do next. Can't recommend Dr Porres enough!
He was extremely knowledgeable, patient, warm, friendly and thorough. I trust him and I will see him again for my son's eczema. So pleased with this doctor!!
He is so nice and so easy to talk to! I was a new patient but felt like just chatting with a knowledgable friend. He is also very professional. He provided very clear explanation to my questions. The staffs were also very polite and efficient. Highly highly recommend him!
I think this doctor is extremely competent, pleasant, and good humored. He takes the necessary time and makes an effort to explain things you need to know.
Dr. Porres is always friendly and professional. I really appreciate that he spares enough time to answer my questions or concerns.
Dr Porres was expedient, professional, and very caring. He took time to listen to my concerns, and the procedure was quick, painless, and was fully explained to me beforehand. He is excellent.
Costume Service was very Efficient, Doctor was very professional.
the office was old and outdated. borderline unsanitary. I went for an entire body screen for skin cancer as it runs in my family. he ended up only telling me what to look for and barely even looked at my skin. could have google'd skin cancer and saved me the time and money.
He is very nice.
Amazing doctor- he listens to everything you have to say and adresses all ur problems... He takes his time examining you and welcomes any questions. Highly recommend him
Dr. Porres is very kind and cares about the patient. He was very informative, and made sure I understood the terms and what he was talking about. The office is a little dingy, but the service is wonderful.
Great doctor. Great personality. He takes time to listen and discuss your condition thoroughly and make sure you understand everything. Best I've been to. I highly recommend him!
Dr. Porres's office was busy when I arrived late in the afternoon but I was seen quickly. He took care of my issue in just a few minutes and was very engaging. I felt very comfortable with him and definitely recommend him.
Very professional, pleasant and informative.
The doctor was very attentive and patient. He made effective recommendations.
Dr. Porres was really professional and nice. I am sure to come back on another occasion.
Nice Dr. but I still need to see if he will be able ot help me.
Very professional. Unlike most dermatologists, did not automatically recommend his own expensive creams (usually nondescript and with high markups). One of few local dermatologists who takes medicare patients. Would definitely use him again.
Very attentive and knowledgable. The office is a bit dingy which freaked me out, but the service was exceptional!
Nice doctor explain. All very clear. And care about you situation
Very funny. Very nice. Great visit
an outstanding medical professional..unlike most doctors who would just refer other specialist round and round in a circle....took care of my issue immediately...in and out in under an hour....
He was nice, listened, good not great. Wait time was short, diagnosis and assistance with my scalp issue was ok.
Left my insurance card at home, front desk hassled me for 30 minutes insisting they receive a physical copy of it .. and would not simply call my insurance company to verify information or use the information/ID docs I provided. Front desk left all the patients names visible to the waiting room. I asked why, and Front desk said she didn't have time to cover yet (It was 1:30PM ...). HIPAA violation? On to Dr. Porres ... what a great guy :) He made my visit pleasant and was very funny!! Might I add .. if Christopher Walken had a brother, it would be Dr Porres (looks, voice, etc). Took his time to explain everything.
Long wait to see the doc but it was late in the afternoon. I did enjoy Dr. Porres though. He was will to run a test to alleviate my fears but also made it clear that I was fine to "wait and see". I decided to wait on the test but I appreciated how he explained the options.
He was very professional but at the same time was friendly and created a comfortable atmosphere. He was also honest about the procedures I needed (or rather did not need) rather than try to 'sell' me on things, and took his time to explain it all- it's uncommon to find such a patient doctor...
Very knowledgeable and professional. Thanks!
I loved Dr. Joseph, He was very attentive, caring , and gave me all the time i needed to go over and over my medication . he is truly a great Dermatologist that is hard to find these days .he care about the person in the front of him Not Having a Spa out of his Practice like the rest of them . I love Him , and I'm so glad his my Dr now . I travel all the way from Mclean to see him but its worth every mile i drive .
Dr. Porres was kind and easy to talk to. I will definitely come back again.
I enjoyed my visit but didn't like the fact that I had to wait more than 30 minutes beyond my appointment time. However, the doctor had great bedside manner and his staff was very polite.
Very nice and professional explained things well
I would expect a dermatologist to at least "look" at your skin!
Dr. Porres is a charming, obviously experienced physician who did not push products or try to rush me out of his office. He was honest about treatment options and outcomes, and patiently answered all of my questions. The staff was polite and friendly, and I don't think I waited more than 5 minutes to be seen. By far the best experience I've ever had with a derm.
He is really good, he took his time asking me a questions which may cause my problems,and I show him a name of pills which other doc gave to me to wash away my rash, and he told me that's very strong pills and explain why, instead he gave me cream which is start working less than 24 hrs!!!!.My face was clear. I recommend this dr. Also I was in hurry on that day of my appointment but I will come back soon for another skin problem.
Very knowledgable and friendly.
Very very smart and didn't push products on me. He wanted me to ask anything and knew his stuff!
Pleasant and effective
Dr. Porres was friendly and informative! While the office isn't much to look at, the staff is efficient. They sent my prescription to the CVS one block away so it was ready to be picked up when I arrived.
excellent doctor, would definitely recommend. No wait, and efficient staff.
