Excellent doctor, excellent staff, can't say a bad thing about the experience. Positive on everything and A+++++
Awesome as usual! I love Dr. Massachi...he really cares about my health.
Very organized and on top of it office, doctor returns calls promptly, tests done on site, which means results come back faster.
Quick turnover from Dr. Massachi however I would prefer he be more thorough. Didn't care to listen to concerns or take the time to explain his diagnosis. Seemed to want to Get me outta there and said we could look deeper into the issue in a follow up. Seems like he wants another appointment to bill my insurance.
Dr. Massachi was personable and clearly explained everything to me during my initial visit today. His initial consult to get my medical history was the most fun I've had in a while and though I have strict orders to improve my health - I know because of our conversations it's all to make my quality of life better.
What a genuine guy! So nice to interact with a caring human and not a doctor who robotically goes through the motions! Very happy to have found a doctor I can create a relationship with
Absolutely wonderful. Great doctor, great office, great everything.
Excellent experience overall. He's a great doctor, and I have recommended him to my family.
Doctor Massachi gave me a very good first impression. He made an effort to engage and make me feel comfortable. He makes eye contact (which is very important to me) and seems to genuinely care about my health history. He listens and I never felt rushed.
Dr. Massachi was really friendly and easy to talk to. He explained everything carefully (and clearly). It was a great doctor experience!
Dr. Massachi is always great! He's got amazing bedside manner and a calming presence that is needed when you're paranoid about your health all the time, like me.
I went to see Dr Massachi for an annual physical. He was great from beginning to end--very professional and thorough in his examination. My only issue with my experience is not with him, but with his secretary--she is extremely cold and unwelcoming. Apparently no one ever taught her that "Please" and "Thank You" go a long way.
Can't say enough good things about him and his staff.
Dr. Massachi was very sweet and thorough. I liked him a lot, but the parking was way overpriced and the woman at the front desk in the office was pretty rude. I don't think I would go back for these reasons.
Dr. Massachi is an active listener and takes the time to listen to what your needs are. I left my appointment with the feeling that he genuinely cares about his practice and his patients. Highly recommend!
Very thorough and makes me feel very comfortable the whole time. Highly recommend his office and staff.
Amazing doctor! Def takes the time to listen to your illness issues and gives great advices to help cure your needs. Very professional and clean modernized office space!
He's a fine Doctor whom I trust.
Dr. Massachi was very nice, friendly and professional. I liked it and would recommend to any of my peers.
Dr. Massachi was wonderful. Highly recommend. Friendly staff and clean, elegant facility. what's not to love?
I couldn't be happier with Dr. Massachi. He's extremely educated on small details of seemingly every aspect of health. He had answers to all of my questions and made me feel very comfortable during my visit. He also is very easy to talk to and an overall really nice guy. I would highly recommend him to anyone I know. Hes located centrally, in Century City which is convenient for me. But even if I moved further away, I would make the drive to his office. I have no complaints about any part of any of my visits I have had with him. Highly Recommend.
love dr. massachi!! he always makes me feel comfortable and i can tell he cares. great western doc :)
Dr. Massachi is great and goes straight for the issue with no hesitation. He diagnoses quickly and refers to specialists when not 100% sure. His staff is also incredibly friendly. The receptionist already knew my name before I said a word (probably because I showed up right at my scheduled time).
Very professional doctor ,give very helpful advice! Short wait, quick blood test and got the result by phone, Which was made by the doctor himself. Very happy that I found Dr. Massachi.
Very friendly, very honest, and very caring!
Today was my first time seeing Dr. Massachi and it was very quick just to determine the cause of recent stomach pain and be sure it was nothing too serious. Overall, though it was a good experience and I am very happy. I will likely return to him in the future.
Informative, polite, quick.
So far so good!! Problem isn't solved yet but Dr. Massachi came up with a game plan for going forward, and since the problem wasn't solved the first visit, cancelled the appointment, so we could get results from the next one!
Ive seen Dr Massachi for a year now and he is consistently great.
Dr. is very nice, knowledgeable and straightforward...and cares about my health.
Great first impression... looking forward working with Dr. Sasan.
I've been a patient for 4 years. Dr Massachi, hands down, is the most thorough, professional and friendly Doctor that I have ever had in this city. I highly recommend his office to anyone seeking outstanding medical care.
Excellent doctor, knowledgeable and caring. Short wait time. Excellent staff.
Fantastic doctor. Very caring and takes the time to know you. Conveniently located in Century City in a medical office building. The staff are super nice and helpful.
Dr. Massachi is amazing and I love his whole office-- they're good at taking my blood, he's great and conscientious and thorough. Also super nice. I did wait over 30 minutes today, but I also was 8 minutes late so I may be partly to blame. Plus since he spends so much time with me, and I'm healthy, I think it's worth it.
Very attentive and sincere doctor. Will be seeing again, also nurse Belia was very sweet and knowledgable.
Great experience over the past 2 years with Dr. Massachi!
Dr. Sasan was the most excellent doctor I've seen in LA. It was my first time and I went in for an annual checkup today. I was called in, in a very timely manner. Dr. Sasan was professional yet also personable, and seemed very invested in my well being. His nurse and staff were super supportive, friendly and over all lovely. I even got a goodie bag at the end of my appointment! His office is conveniently located in a prominent medical building with all kind of specialists, radiologist, etc, in Century City. I would highly recommend this doctor if you want a pleasant experience with a doctor and staff that are invested in your well-being. Thanks Dr. Sasan!
Dr Massachi is kind and very competent. Great doctor!
Visits with Dr. Massachi are always quick, pleasant, and efficient. He has great bedside manners and his staff is very nice. I would recommend Dr. Massachi to everyone.
Great guy. Very professional and down to earth. The receptionist was friendly and the wait was not long at all. His team was able to draw blood and take x-rays on site which saved me multiple trips.
Great guy - definitely will go to him again. He was very apologetic about the wait but he was worth it.
I came in for a general physical. I did not wait around long. The staff was friendly. The doctor was attentive and thorough. I had blood drawn in the office and that was done quickly as well.
He's great! His staff is also really nice and I was very comfortable. Really wonderful.
awesome! everyone was really nice and helpful there. seriously i was impressed. my last family doc wasn't helpful and i waited 1.5 hours before i saw him. not ok! this was a way better experience.
So glad I found Dr. Massachi! I was so unhappy with my primary care physician prior to him, it's such a relief to finally feel like I am in good hands! He has been incredibly helpful during every visit. Extremely friendly, personable, and has a sense of humor! He makes the environment very comfortable. Also very assistive through anytime I have emailed him any concerns. His staff is also very helpful. Visits are quick and easy, addresses my concern and takes care of it immediately. I also love how fast he gets lab results back to me every time!
Very minimal wait at check in. Doctor saw me first and took down my complaints. Ordered x-rays and blood work which were done in the office. Whole appointment (new patient) took under an hour. I am very pleased he is my new G.P.
I'm so glad I came across Dr.Massachi! I was so unhappy with my prior G.P., but now I am extremely happy that I feel like I'm in good hands! The wait time is very minimal. He is extremely friendly, kind, personable, and has a sense of humor! Makes the environment very comfortable, and not like those awkward doctors visits. Every time I have visited it has been quick and easy, as he immediatly resolves any concerns I may have. I also love how the lab is in-office, and he gets the test results back to me in no time! He has also been very assistive any time I have emailed him with a concern. His staff is also extremely helpful.
Probably the only doctor I look forward to seeing. I have been going to Dr. Massachi for my annual physicals. I was referred to him by father who is also extremely fond of Dr. Massachi. He is extremely professional and caring.
Fabulous, smart doctor. Takes the time to really discuss and address anything you need. I have plenty of things that I would easily feel uncomfortable talking about and Massachi does not make me feel uneasy about any of it.
Dr. Massachi, and his team, were outstanding! I experienced nothing less than congenial, thorough and professional consultancy in a beautifully appointed modern office. Extremely pleased!
The office and Dr. were great - I'll definitely be returning. The only downside was scheduling the appointment through ZocDoc rather than calling the office directly. Apparently the two systems don't communicate as far as the offices real time schedule, so the available times listed, weren't actually available. I received appointment confirmations from the ZocDoc system, when in reality, the appointment was not available at the office. The receptionist squeezed me in since it took me an hour to get there. The bottom line is: the dr. is great - this app, not so much.
Dr. Massachi is my favorite doctor I've ever been to. The scheduling is easy, the office is nice, the entire staff is friendly and most importantly he is a wonderful and trustworthy doctor. I live in NYC now, but will probably still try to see him in LA for regular checkups when I am there. I would recommend him to anyone and everyone.
Very professional and very thorough, I would recommend him to anyone looking for a great primary care/ internal medicine doctor.
Dr. Massachi is very approachable and friendly. I love my experience every time I visit.
Amazing, I left feeling better!
Everyone was very pleasant. Dr. Maasachi listened and was very thorough. I appreciate that.
I feel very comfortable and he spent plenty time with me
Very nice! Staff was friendly and professional. Wait was not over-long, and I was offered water and hot tea. Doctor was also friendly, seemed thorough, took my concerns seriously, answered my questions. So far so good!
Dr. Massachi is a great doctor. Very kind and helpful. Receptionist on the other hand didn't seem like she cared much for her job.
I didn't wait very long and everyone in the office was professional. Dr. Massachi was very personable and I was pleased with my care. I just got a routine physical exam, so it wasn't anything too complicated, but everything went smoothly.
Dr. Massachi was SO nice and awesome, and really took time to check up on me. It was incredible. Also, the nurse did a FANTASTIC job with taking my blood and everything else, which usually nurses find hard with me (I guess I have bad veins? Anyway, he ROCKED). Everyone was so so SO friendly and easy to work with and made me feel comfortable. The wait would have been shorter but I was late, so that's my fault. I will definitely be back.
Great doctor. Very kind and concerning!
Overall, I felt as if Dr. Massachi was very thorough in his process and answered all of my questions sufficiently. I'd come back again!
Dr Sasan is a great knowledgeable and professional doctor. He is thorough and very effective in communicating. I highly recommend him and his practice to anyone. Thanks.
I really like the doctor. I actually didn't care for his receptionist. She was not very friendly.
Very professional, knowledgeable
Great doctor and looking forward to having him as my primary health provider.
Dr. Massachi was extremely professional while having a very personable and reassuring bedside manner. The office staff was courteous and helpful. The wait time prior to the examination was reasonable and, once placed in a room, the nurse and doctor conducted the tests and examination right away. The office is also conveniently located on the westside in Century City in a building with reasonably-priced valet parking (under $10). In sum, I highly recommend Dr. Massachi.
Great experience, he was incredibly kind, attentive and listened to all my little worries.
Very friendly staff. Most thorough physical process in the best way possible. Listened to my concerns and adressed each and every one, specifically with a detailed understandable answer. Glad to call Dr. Sasan my new dr. Would highly recommend if you are looking for a Dr.
DR Sasan was a very good Dr...
This doc is amazing. I was seen right away and he is very friendly. He took his time with me and did not rush our time together. He listened and examined me and I am very happy with the solutions he proposed. I highly recommend this doctor.
Dr. Massachi makes you feel comfortable and relaxed. I enjoy how you can tell him anything without judgement. Please note that he gives you tests results over the phone and not in person.
I loved DR. Massachi he took his time with my physical was very informative . His office is very nice easy parking . His staff was very friendly . I definitely found my primary doctor ! He was very professinal and caring .
Very welcoming environment. I felt very comfortable with Dr. Massachi.
very impressed with dr. Massachi
Very helpful, listened to my medical concerns and came back with some suggestions on how to improve my overall health.
I was very impressed with my visit & would definitely use Dr Massachi again
I didn't feel like Dr. Massachi listened to me very well. I came in with the same rather uncommon symptoms as my daughter, who had already been diagnosed by her pediatrician. Dr. Massachi didn't seem to think I had the same thing, but he didn't say why. I like doctors who will talk to me about why they are making the recommendations they're making, and he was not one of those doctors. On the flip side, the wait time was short, and I was able to get a next-day appointment through zocdoc. However, the office staff was not very friendly. The parking was valet-only in the basement, expensive, and took a long time to get my car.
Dr. Massachi is great! He's a friendly and knowledgeable doctor who definitely makes you feel at ease. Great staff, nice & clean office space, and all around pleasant experience! I will definitely return.
Dr.Massachi was wonderful, addressed all my issues and made me feel very comfortable and he definitely knows what he is doing.
I was seen within less than 5 minutes of my appointment time. Very nice doctor. Would definitely recommend!
Dr. Massachi is great. He is incredibly thorough and has such a wonderful manner that I always leave his office feeling well taken care of. He asks questions and is not afraid to offer an opinion, which I find refreshing. So glad I found him!
Very caring and thorough! I would definitely recommend Dr. Massachi.
Really thorough and professional doctor. Definitely recommended. The only negative is paying for parking at the office. There may be cheaper parking spots but the one I found was $9.
Great doctor. Very thorough. Great bedside manner.
He was an excellent doctor
Great doctor and nice nursing staff. There always is a wait, but that's the only issue I ever have.
Very nice, he listens, nice office has well. A+
Really fantastic doctor. Personable, informative, and fast. Glad I finally found a good doctor in Century City!
Great staff, terrific nurse. Really a great experience overall. Dr. Massachi is terrific.
I really think Dr. Sasan Massachi is a someone who's concerned about his patients. I did have a long wait time but he had another patient that was ill which I assumed and once seeing him realized he likes to take time with his patients. He is having me come in again tomorrow for a full physical to ensure I am healthy and will have the best health.
Great first visit. Office staff is quick & efficient
Quick, painless, empathetic. Took extra precautions and phenomenal follow-up. Highly recommend.
went very well and i was in and out in 30 minutes.
Everything was fast and efficient. Staff and Dr were very friendly!
Dr. Massachi is an awesome doctor--very attentive, caring & also keeps up with research! If I weren't moving out of the LA area, he'd still be my primary care doctor.
Great Doc , great energy , very polite !!!
He's young, smart, and caring. He has multiple awards for patient care and really takes a lot of time for each patient. After asking about my family history, he even went out of his way to make sure my parents were getting properly screened for certain cancers (they live out of state) that run in the family. In addition, I could easily get an appointment, and the wait was very short once I was there. The support staff was very so-so (the x ray tech made me feel dumb for not knowing what to do and the nurse was complaining about being there the whole time), but the doctor himself was awesome and comfortable. I'll be going back for years to come.
Very professional and worked with me to make sure I felt comfortable about the information I received and took enough time too. Great doctor will definitely go back if I need to see an MD again.
Dr. Massachi was very professional and showed a great concern for my condition. His staff is also very professional, courteous and friendly. My experience visiting this office was very positive. I only wish I had PPO coverage. If I did, I would definitely come back!
Dr. Massachi is great! He's professional, thorough, and caring. I would recommend him to anyone.
Dr. and staff genuinely care for and care about their patients. They are very warm, welcoming, and attentive to your needs. I've never had to wait more than 15 minutes or so to be taken back and if for some reason there is a little bit of a wait, they don't just keep you sitting there, they apologize, offer you water and let you know how much longer. I would recommend him to everyone!
I found Dr Massachi to be the best doctor I have visited. His staff were also exceptional. The questions I asked him were ones I had asked many doctors in the past. Dr Massachi was the first to show a good understanding and actually solve the issue that had plagued me for many years. My opinion is he is extremely competent knowledgable and a generally pleasant person to consult with. I wrote a letter to him to thank him but never posted it so Im glad I saw this forum. It is not easy to find a good doctor and Im glad to have found one.
Dr. Massachi is always quite prompt and very thorough.
Super friendly, and it seemed like he really cared about my symptoms, unlike a lot of general practitioners that seem like they're just going through the motions.
Love Dr. Massachi. Very informative and pleasant.
Dr.Massachi is definitely the best doctor I have ever seen hands down. He spends so much time with you and makes you feel like your not one of the 50 patients he's seen that day. He is so good about following up to. I got a call from him one day after my appointment to go over results and we have been emailing back and forth as well. He said he would even call this weekend to go over the next steps I need to take. He takes his job very seriously and is obviously good at it. Considering his busy schedule its great that he is a 24/7 doctor, following up with patients on weekends. If you want someone who genuinely cares about your well-being and keeps you posted daily go see him!!
My visit to Dr. Massachi's was fantastic. His office was clean and classy. He actually listened to what I had to say and did his best to work through my issues. He is very professional and caring. Even though my problem didn't turn out to be as serious as initially though, he still kept in touch and followed up with me just to make sure everything was good and to offer additional advice. Unfortunately, that level of attention is RARE with other doctors in my experience so I really appreciate that he went the extra mile for me.
Dr.Massachi is everything you could ask for. Kind, up to date & his upbeat spirit & charm make everything that much better. I always leave this office knowing more & feeling better. Care @ it's best.
Understands a patient's perspective and does an excellent job communicating, listening and collaborating on solutions. Best internist around and for good reason. You will be glad you went to see him.
Could not recommend Dr. Massachi more highly. Exceptionally thorough and inquisitive during the evaluation, so I felt in very competent hands. Was super kind and did not rush through the visit at all. The waiting room time was minimal. Such an approachable and nice man... Cant say enough good things about my experience. He's my go-to from now on.
I think this doctor is extremely arrogant, condescending, sarcastic, dismissive, not very knowledgeable, a "know-it-all" who doesn't really know it all. I felt extremely offended and uncomfortable within the first 2-min of the appt and wanted to run out of there.
Doctor Massachi is a caring and reliable doctor! In a world where health insurance companies/managed care have ruined the quality of the doctor-patient relationship, it seems Doctor Massachi is one of the rare doctors who takes his time with his patients and discusses their problems and possible solutions very thoroughly. His personality and the way in which he interacts with his patients is sure to make them feel at ease. The waiting room staff and nurses are equally friendly I highly recommend Dr. Massachi.
He was really great very friendly I'm tell all my friends and family about him
Very professional and informative
Great experience! If you are looking for a doctor I would highly recommend you see Dr. Massachi.
After pretty much hating every doctor I have been to in LA. I actually had a really great experience! Totally recommend.
I feel like he was very young and inexperienced. He just sent me to more doctors without ever helping me. He was very nice though.
Best Internist doctor I have ever had in my lifetime. Caring, careful , compassionate and quite knowledgeable in his field. Devotes his full attention in office visits. Wonderful Internist! Highly recommended!
Had a great experience w Dr. Massachi. I've been looking for a doctor like him for many years. A friend of mine referred me to him and I would definitely refer him to others. He is sincere, friendly and understanding. He explained my health issues very thoroughly and called me to follow up which I thought was very caring. Thank you Dr. Massachi!
caring, not pushy, wonderful doctor
Best doctor I've ever met. I went to him for a physical about a month ago, a follow up a couple of weeks later, and another follow up today. He listens. He really cares. He doesn't scold. He gives me all the time I need. He helps me deal with health issues I need to address. He coordinates my health care with other doctors. I feel like he is my personal health care manager. I wish I'd met him years ago.
I highly recommend Dr. Massachi, he was very courteous, and honestly took his time to listen and learn about everything he could, concerning my health. His staff was also very nice and made me feel comfortable during my visit.
Dr. Massachi is great: extremely professional, kind, and courteous. I HIGHLY recommend him.
Thorough, knowledgeable, and down-to-earth doctor who seemed sincerely engaged in my well-being.
