He was quick and decisive with his preliminary diagnosis although it didn’t feel as though he was simply jumping to conclusions. He laid out a clear plan to assess the diagnosis over longer period of time. Felt like I was in great hands with Dr. Ash

Dr. Ash was extremely professional, knowledgeable, insightful, and thorough. After being a bit nervous about switching my PCP after several decades with my previous PCP, I feel very confident about going to Dr. Ash for my healthcare needs going forward.
Dr. Ash and his staff were excellent. They were very helpful guiding me through some insurance questions. When I was in the office, it was all very efficient and clean. Dr. Ash and I talked through my medical history and he explained everything he was going to do. I highly recommend Dr. Ash and his office.
Very professional answered all of my questions
Dr. Ash has a great demeanor. He cares a lot about his patients, speaks calmly and clearly without making you feel below him.
Dr. Ash is a real professional. One of the things I like is the way he talks to you like a real person. He explains things in a way that you can understand, but not in a way that feels belittling.
Quite possibly the best medical care experience I have EVER had. Phenomenal physician. He was able to finally give me answers to several medical issues other physicians rushed past.
Took a while to get in but the nurse was great with a quick prep time before I saw the doctor. I had digital copies of labs I wanted to send and she offered her email address to receive them. This was my first visit with the doctor and he was patient and attentive as I explained my history. His problem-solving was fast and effective.
Dr. Ash is very considerate and takes his time to make sure you feel comfortable and ensures he answers any and all questions. Very happy with my visit with Dr. Ash.
Initially, I went to see Dr. Ash for some "lady" issues. I was pretty anxious and nervous because I was seeing a male doctor for some female issues, but Dr. Ash bedside manner was fantastic and his demeanor put me at ease. He spent a considerable time asking questions and testing samples, and I didn't feel rushed at all through the whole process. I felt like the quality of his care was very comprehensive, and I'm certainly considering making him my primary care physician. I highly recommend this doctor!
Dr. Ash was thorough with questions and exploring for information. Was able to assess my situation and provided clear explanations for his diagnosis. Everything seemed reasonable, and he displays a thoughtful and caring personality.
He is the best Doctor ever!! I really do think so. He is very professional, smart, kind, friendly and patient!
Prompt, straight to the point and covered all of my concerns. Great doctor.
I really enjoyed this visit and believe I've found a top notch primary care physician near my apartment in Brighton. I would recommend him to anyone needing a doctor in the Boston area.
He was great, a little unclear on where to go from the actual room after he visited with me to go get blood work. His staff wasn't exactly helpful either. Additionally, little unclear on exact next steps to be taken as well, regarding prescriptions or when I'd hear/who would be reaching out to me. Other than those 2 things it was quick, efficient, and just what I had hoped for. 10/10 on it all!
Excellent physician! Very friendly and knowledgeable with calming and compassionate demeanor. Couldn't ask for better.
Dr. Ash delivered with empathy and compassion.
Very cursory examination for an annual physical for a new patient.
Dr. Ash is fantastic! He was knowledgeable, thorough, and had a great bedside manner. I'm glad to have found such a great PCP in Boston! His staff and ancillary medical professionals were very nice as well.
He is very professional and kind. He was thorough with my exam and took time to ask about my schooling and even offered non-medical advice. Thanks Doc!
As always, right on the money. I've seen 2 other doctors since an accident I had. They both essentially told me to wait for the pain to eventually subside. He was the only one to suggest an alternative reason, had me take a test and he was right. Always looking out for his patients. Were I to change town, I'd easily drive 50 miles in order to see him before anyone else.
Dr. Ash was very professional and helpful.
I guess I would say Dr. Ash's bedside manner was "good enough". He was very nice conversation-wise, but was not very considerate. After a pap smear, he went behind the blinds to do whatever he had to with the sample. I was left sitting there with my legs up for a few minutes uncomfortable and unsure of what to do with myself. After he came back, he started to talk to me, my legs still up, everything private still facing him, even though I didn't need to be after that. When he was done talking, he just told me feel free to leave, and I had to ask him what I was supposed to do with myself at the moment to get my legs down and clean up. The office staff were horrible. It took me multiple tries to have them send test results that I ended up submitting late because of their errors. That was fine, mistakes happen, but what baffled me was the staff got mad at me and blamed me for not receiving the results. One lady was very frustrated for no reason and said I had gone in to grab them already, which I probably would know if I did, and when I said I didn't she repeatedly said I did. Which if there really was someone that picked up my results and it wasn't me, you have a big case of privacy breach in front of you. I ended up just letting it go and asked her if she could just send another copy. The nurse I had on the other hand was a delight and extremely professional and considerate. One detail that I remember especially well was that she told me some people may not be comfortable with the hospital gowns, and so she brought 2. One for the front and one for the back if I would like. It was a very nice touch. Overall I really wouldn't recommend this practice. When I really searched myself and considered if I were talking to a friend, it would definitely be a "Never!" recommend, but Dr. Ash seemed like a nice person in general and the nurse went above and beyond, so in the end, I squeezed out a reluctant "probably not".
Quickly, friendly, professional. Everything you want in a PCP.
Great experience! Office staff was very personable. Dr. Ash gave a very comprehensive exam and took the time to answer all of my questions. Looking forward to continuing my care with him.
Didn't get to meet with Dr. Ash, but receptionists were unpleasant and distracted.

It's been a while since I have been to a doctor, it's not my favorite thing. The staff was so pleasant even though you could tell it was very busy in the office. Dr. Ash was very attentive. He took the time to listen and really get a feel for what issues I was having. It was one of the best doctor experiences I have ever had and I will certainly be returning.
Dr Ash is very approachable and understanding. He was genuinely concerned about what was going on with me and I could tell he was committed to figuring it out. Thank you!
Doctor Brian Ash is honesly the nicest doctor I've ever seen in the past few years. I had my annual physical exam with him. He was very patient and friendly. He answered all my questions, and explained a lot of medical stuff that I was confused about. He also wrote down all the important notes on the paper for me to review later. He is really nice! I strongly recommend him.

Dr. Ash is great, super attentive to details and listens to his patients. Would highly recommend!
He was very considerate and friendly. I loved that he was taking his time to listen and share, as well as ensuring I am getting the most accurate professional advice. We talked for almost an hour about my health concerns, some of which I didn't realize were concerning. I was glad to have made my appointment and truly thankful for his service.
Best initial PCP visit I have ever had.
Dr. Ash is always pleasant, and carefully explains his ideas while making sure you understand what he is saying. He doesn't rush you, and is so easy to interact with. This is what professional excellence looks like.
Dr. Ash was very friendly and did a great job of patiently listening to my concerns/symptoms and giving a detailed explanation of what he believed was going on. Highly recommended!
Can't say enough about Dr. Ash, I'm a new patient of his but can honestly say that I've spent the better part of the last 5 years looking for the right PCP in Boston and the search is finally over.
Dr, Ash is great! It is no wonder he is named top doc in Boston! He is caring, and explains everything in a clear and calm way. Amazing. His nurse/medical assistant was awesome too. I felt respected and my symptoms were not brushed off.
He was very insightful and caring at the same time.
Everything was great - the nurse was very nice, wait time was short, and Dr. Ash is very friendly, helpful and was able to explain everything very clearly, which I find very helpful. Thanks!
Really nice guy, listened to my concerned and offered helpful advice and treatment. Highly reccomended
My overall patient experience, from start to finish, was everything you could ever hope and ask for. I've spent almost 3 years trying to find the right doctor in Boston and I'm happy to say that the search is over. The medical acumen and accolades of Dr. Ash will speak for themselves, but just as important is that he's comforting and great to talk to. It's something I've always felt is important when choosing a PCP, and was relieved to finally find it. In addition, he always made sure I expressed any concerns, and spent as much time with me as I needed. To top it all off, the front office staff went above and beyond to make it a convenient and seamless experience for me. Very happy to have found this office, I just wish there were more like it.
Dr. Ash is friendly and open about his proposed treatment. He will provide his thoughts and allow you to work together to determine the course of treatment.
Very knowledgeable doctor, could tell me a lot about the symptoms I was having.
Dr Ash was very nice, assuring, and offered me lots of small procedures so I could get the most out of my visit!
Very Professional. I felt he was genuinely interested and concerned. Instilled confidence.
So helpful !!!
When I met Dr. Ash, I was so frustrated with the healthcare system, having seen several doctors with minimal relief to my symptoms. After meeting him, I can honestly and wholeheartedly say that Brian Ash is among one of the best physicians in Boston that I have ever had the pleasure to come across. He genuinely cares about his patients and takes the time to get to know them as an individual, factoring in their complex history before jumping to any rash conclusions. He also spends a considerable amount of time addressing concerns and answering questions in great detail. He is extremely knowledgable, professional, approachable and passionate about patient care. Would highly recommend to anyone seeking a new primary care provider without any hesitation.
Dr.Ash is very patient and explain everything nicely. I choose him to be my PCP during summer when school clinic is closed.
Dr. Ash is just simply an awesome Doctor. He is very knowledgeable. He was my husband's doctor at first, then I decided to make him my PCP as well. And recently, I have referred my brother-in-law to him as well. We all love him!!!
I think Doc got busy with another patient which can happen so not big deal
Dr. Ash is a very thorough and compassionate physician. He never seems to be rushing me and always has a good plan for whatever I throw at him.
He is the only doctor I have ever been to that didn't seem in a hurry to finish the appointment. He really took the time to make sure everything I wanted or needed to talk about was discussed in length.
Dr. Ash is always very professional, takes time to explain things including answering my questions, etc. I would absolutely recommend him.
He is an excellent thorough clinician. He never rushes through the appointment and asks lots of questions to make sure you are at your healthy best. Fantastic primary care doctor with great interpersonal skills.
Dr. Ash is the PCP I've been looking for for years.
He was awesome---very thorough and took his time to make sure he got every single detail. This was the best doctor appointment I've had in a long time in that he really heard me out and gave me so much more information and advice than I've received at other doctors lately.
Best doctor I've ever seen in my entire life. He really examines you and he's not judgemental, he listens with care, and he's smart. Everything you tell him makes him think of more possibilities. He knows what he's talking about. He's awesome!
Highly knowledgeable, friendly, and helpful
Dr. Ash was excellent and knowledgeable. He took time to talk after the appointment to answer questions. His office works hard to prevent wait-time and they seem to succeed in this.
He was really nice and knowledgable. I was looking for a smart doctor and was very happy to find one.
Wonderful caring physician. Great diagnostician and gives good instructions and explanations with new medications. His staff is very friendly. Overall, you get a very welcoming feeling when you come into the office and don't feel rushed if you have a complicated problem. That's why I don't mind waiting a little for Dr Ash when he runs behind. It means someone needs a little extra time.
Very friendly physician. I went in and had a few random issues/questions about my health and he was able to comment and provide feedback with ease.
Great physician and very quick.
Dr. Ash is always a true professional, knowledgeable and courteous. He is easy to talk to because he listens and make a human effort to comprehend and respond to patients inquiries.
Dr. Ash and his medical staff are incredible care givers. With easy booking and timely visits. I highly recommend
Waited exactly 1 hour and 3 minutes. He's a great listener and tries to solve your problems. But the wait was way too long. They should put into consideration you have to pay for parking or maybe not book too many patients in one day it wasn't nice waiting that long
Even though he was behind schedule he still attended to what I came in for (routine yearly exam). Knew what specialists I needed to see since I've moved to new insurance.
Earlier this year, I made some research to change PCP and I could not be happier. If he were to move, I'd commit to long drives just to keep him as my physician. Whenever we meet, it always feels like he has all the time in the world to discuss and understand my need. He actually caught little things that no other doctors had raised purely on observation. His appointment book usually runs a little late but I'm not holding against him. My previous doctor was always free and it didn't make him better. take care
Incredibly helpful staff, the entire visit was incredibly quick in an out in less than 45 minutes and that was with getting blood drawn.
Great physician! He screened for complications with my medications that no doctor had ever done. He also provided great referrals for some specialty physicians.
Nice and smart guy. I look forward to him being my PCP
Dr. Ash and the office staff was very nice. Dr. Ash was thorough, inquisitive and easy to talk to.
Very good doctor, thoughtful about diagnoses, does not run tests just for the sake of running tests. Great bedside manner, he really listens and works with you, I would definitely recommend.
Dr. Ash was really great. I was seen immediately, he was very easy to talk to, he thoroughly answered my questions, met all of my needs. I would highly suggest seeing him!
He was great. He carefully listened to all of my concerned and addressed them.
As a new patient, I'm always curious as to how things will go. Everything was great. Dr. Ash was very attentive, heard me out and asked many questions to make sure he understood my concerns. He was both thorough, as well as conservative in response to my needs. I look forward to having him as my doctor.
Only met a couple of times so far but I like him. He was pretty perceptive in highlighting a couple of things about my self that he thought he could help with and he did. Very gentle and gives you as much clarifications as you're willing to take.
Thorough and personable.
Dr. Ash is kind and understanding and very patient. He's thorough and doesn't make an appointment feel rushed, but also gets right to the point of why you're there. I was nervous going into my appointment but he made me feel comfortable and taken care of.
Dr. Ash is great - very thorough and patient when talking through ideas/options/concerns. He is genuinely caring and accessible which is much needed for a busy life/schedule (grad school for me). I get nervous when I move to a new area and need to find a new doctor so I feel super lucky that I found him. Highly recommend if you're looking for a new PCP!
Excellent doctor, very kind and listens to his patients.
Dr. Ash was extremely thorough and took the time to explain exactly what may be wrong with me, why and how it happened, and what to do to fix it. He was incredibly patient and understanding - best primary care doctor I've had the pleasure to meet so far.
Dr. Ash always listens to my concerns. Whenever something else pops up that sends me for a visit, I can count on the thorough explanation and examination that is given.
Dr. Ash has moved to a new office and this was my first time at the new place. He was running late but I'm very understanding of that. He really takes his time with patients when necessary. I've been the recipient of a long appointment with Dr. Ash and because of this I don't mind having to wait a bit.
Dr Ash is very professional. Listened to all my concerns! Didn't feel rushed or anything!
Best doctor I have had so far. Very smart and up to date on medical knowledge but also takes a common sense approach when needed. Excellent bedside manner - very caring and patient.
He is a real, gentleman doctor. He first shows his caring heart for his patients. Also, he seem to have wide variety of medical knowledge as a PCP. He cares you as God cares you. If you want to love and serve God, you can do it by loving and serving God. I think Dr. Ash fits to this frame of my belief.
very informative and transparent doctor. would suggest to whomever.
I have not had a PCP in nearly 10 years and knew it was time to address some of my health concerns. Dr Ash was thorough, but moreover he was approachable and did not rush through my appointment. Some doctors can come off as judgy and aloof but Dr Ash was very down to earth and easy to talk to. I left feeling very satisfied with the level of care I received.
Brian was a very courteous and thorough in explaining what was going on in my annual physical
I have had numerous primary care docs over the years and Dr. Ash is by far the best! He takes time to listen and I never feel rushed. I highly recommend him
Dr. Ash is a great medical care professional. He is knowledgeable and explains your diagnosis/care plan very clearly. He was patient with me and did not seem rushed, which was a pleasant surprise compared to some doctors i've seen. I'm glad i've found my new PCP in Boston!
Thorough interview/assessment. Always asks clients opinion. Never rushes. Always follows up next appointment. Best pcp I have ever had!
I was so happy with my visit to Dr. Ash, I haven't had a consistent PCP since I was 18. I've never found one that actually listened and cared about my health issues as opposed to just writing them down and handing me a prescription for something that wouldn't help or worse, would add to my issues. He asked many follow-up questions to gain a background of my concerns, and the best part of the entire exam was when he said, "You don't have to live with these issues for the rest of your life, we can take care of them, there are ways." I had always been told that that was it, there was no alternative and I would just have to deal with my symptoms. I felt so comfortable, and relieved and most of all cared for. He gave me the prescriptions I actually needed, as well as a few he recommends for treatment, and referred me to two other doctors for other issues. I am actually looking forward to going back.
Absolutely perfect – short and sweet
Dr. Ash took his time to address the concerns I had about myself. One of the best appointments I've come across. Most Dr.'s I've had, Ive felt like I was being rushed out of my appointment. Thank you!
Dr. Ash and his staff are simply wonderful! Dr. Ash takes his time to hear my concerns
Always nice and treat well as soon as possible. Many thanks!
Couldn't have been more pleasant, helpful, and informative! What a great experience.
Dr Ash was very informative and professional. He gave me enough time to review my medical history. He also gave me sound advice on maintaining my health care
Everyone was extremely friendly and helpful. Really felt helped and heard from the moment I entered until I left.
Dr. Ash. was patient (no, wait... he was the doctor!), thoughtful, and thorough. I felt comfortable.
Dr. Ash listened to my concerns and put me at ease. He suggested multiple rounds of tests to see if we could get to the bottom of my illness. Highly recommended.
Accuracy of treatment or diagnosis
Very good! Seems very knowledgeable and very nice.
I'm always nervous going to a new doctor so I hadn't been to one in a while. Dr Ash was so helpful and caring! I felt relieved when I left with answers and solutions to some issues I'd been having.
Very impressed with the depth of his knowledge and his presentation
he was very professional
Dr. Brian Ash is a fantastic physician and my experience was excellent. I am new to Boston and I could not ask for a better experience. The waiting room was clean and modern and the front-desk staff was friendly and attentive. I did not wait long once in the room and Dr. Ash was very friendly, genuine, attentive, and spent a lot of time with me. Dr. Ash listened and was engaged in our conversation regarding my health and very thorough in explaining and discussing my options. This was one of the best experiences I have had with a physician and he will undoubtedly be my new primary care physician.
Very intelligent physician with a warm and relaxed manner.
I have had multiple PCP's in the past. Dr. Ash surpasses them all. He has an incredible bedside manner, I have never had any delays in the office, he is thorough, and perceptive in his diagnosis and treatment. Very pleased.
Dr. Ash was very thorough and spent a good amount of time with me, even though I was only in for a routine physical. He asked good questions, was attentive to my answers, and explained things clearly and carefully. Highly recommended!
The in-office time with Dr Ash was very thorough. He was mentally present in the room, addressed my concerns thoughtfully and indicated he would give me referrals for specialists within the week. After I left the office; however, I didn't hear anything else from him or his staff. I had to contact the office to get a copy of my lab results, twice. (It seems the first copy was 'lost in the mail'.) And, at several weeks later, I have yet to receive any referrals to, or even names of, specialists as previously discussed. I will probably change doctors and medical teams to an organized group that can provide proper follow ups and support.
All I went in for was because I had a cold and didn't want to miss work, but the doctor took the time to get to know me and made a slew of referrals which I'm very grateful for.
Dr. Ash is a wonderful doctor. He takes the time to explain things and never rushes. He listens to everything you have to say and is very thorough in trying to help.
Since finding Dr. Ash I have never been more satisfied with a doctors, thoroughness, attention to detail, and over all pleasant demeanor.
He was very thoughtful and thorough during my initial visit. I felt very comfortable talkingn to him and have a good sense of trust in him and the office.
