The receptionists were polite & helpful. The nurse who started my appointment was very kind and made me feel comfortable. Dr.Zahir was so nice & took the time to listen to me and learn why I was there and what my concerns were. He heard me and that was very important. The phlebotomist was quick with the needle and made me laugh. I actually really enjoyed my experience due to the caring staff at this office.

Over the course of my time as a patient, I've never experienced anything but absolutely outstanding care from this provider. Dr. Zahir is attentive, kind, knowledgeable, and helpful - he genuinely cares about his patients. The desk staff are exceptionally helpful and have managed to find room in the calendar for ad hoc appointments when I've needed them. I highly recommend Dr. Zahir and his practice to anyone seeking a GP.

I had a list of questions and health problems I had before going to see Dr. Mir. She did a thorough exam and "heard" what I had to say. My 1st visit impression is excellent. I appreciate the time spent listening, advising, and asked if I had any other questions.Quality Dr.

Incredible doctors and humans! Highly recommend both Dr. Zahir and Dr. Mir. Extremely thorough, efficient, compassionate and educated. Not only in western medicine but from a holistic approach. Our entire immediate and extended family all feel the same about their great level of care in addition to anyone I have referred them. I feel immense peace of mind that we have them as our family doctor.

I could not be more impressed by Dr. Mir and the front office staff at Prosperity Internal Medicine. Dr. Mir is kind, gentle, positive and supportive - she listens and communicates better than any primary care doctor I’ve ever had. She is helping me become more proactive at taking care of myself from a holistic perspective. She coaches rather than dictates, offers fresh ideas for problem solving issues and makes me feel optimistic and healthier- and that’s a miracle considering all of the different health issues I have. The front desk makes everything simple and easy and the patient portal is easy to use and helpful. I never thought I’d find a doctor like Dr Mir and I highly recommend her and the practice itself- which lives up to its name so nicely.

Dr. Mir spent time to go through details so that a proper diagnosis could be obtained. Her kinder care always makes me confident of having the best outcome (treatment).I recommend Dr. Mir as one of the best physicians for family care.

Been going to see Dr Zahir for 10 + years. He used to be located in Fairfax but moved to Reston not too long ago. He is the best doctor in northern Virginia. I would not change doctors for any reason!! He is always professional, personable, knowledgeable and takes the time needed to answer all my questions. I would follow him any place he goes.He has been there for me on many medically difficult moments of my life and has always given me good advice. He has even called me after hours to give me results of my labs and personally discuss them with me.I can’t express in words how wonderful Dr Zahir is.On a huge plus his wife Dr Taseen Mir also works in the same office so when Dr Zahir is not available she takes care of my appointments. She is equally as impressive as him. They are wonderful doctors!!! I have recommended many of my friends and family. Definitely give them a chance.

Prompt service. Dr. Zahir really took the time to listen to all my issues.
First time coming to this office yesterday, I feel very comfortable and decided to make him my primary care physician moving forward.

Dr. Mir is the best physician ever! She always takes the time to listen. I never feel rushed or my concerns disregarded. Appointments are easy, the location is very convenient! Highly recommended!
Kate Conner

Go here. I have been seeing the same PCP for 20 years and I suffer from massive anxiety around change (and just in general). I also suffer from ADHD, hypochondria and depression. So to say I was nervous would be a massive understatement. From the second I walked in the door, everyone was kind, professional, patient and compassionate. And a HUGE shout out to the best phlebotomist I've ever come across. I feel blessed to have found such an amazing physician and healthcare partner in Dr. Mir and her staff. She is truly a wicked smart Disney princess come to life but much more magical 😉 Go here.

Dr. Zahri and Dr. Mir are the best doctors. Both are very knowledgeable, patient and have excellent listening skills. I have been going to Propersity Medicine for over 20 years. When they took over the practice years ago, I almost went to another office because I did not know what to expect from the new owners. But to my surprise, the treatment and respect that you are provided from not only the doctors, but from every staff member is so worth remaining a patient with Prosperity Internal Medicine. There is very little waiting time and I have never felt rushed to get in and out of the doctors' office. Before I leave, both doctors always asked" Have I answered all of your questions and do you have any additional concerns". If you are looking for a doctor, look no further. Give these doctors a try. By the way, I did not get paid to write this review. I have been a patient of theirs from the day they opened the practice. All of the above, all true statements.

Wow this place is incredible! Got checked in by friendly staff upfront and was in and out in under 15-20mins from start to finish. Dr. Tarique was very friendly and to the point with helping me with my chronic migraine and even will help me get a permit in VA to tint my windshield (forgot the name of the permit). I’m happy to have been able to find a great doctor that is straight to the point, knowledgeable, friendly and will go the extra mile to help get me setup for success. Thanks again everyone and see y’all soon!

Our whole family has been going to Dr. Zahir/Dr. Mir for years now. They are fantastic! They are very professional, have great “bedside manner”, and take the time to learn each of our unique recurring ailments (such as seasonal or age-related issues). In addition, they have a new PA, Dr. Glass, who is just as great as they are! She took the time to listen to and assess my current symptoms, my typical symptoms, and my medical history and quickly determined the issue (which directly aligned to what I also thought the issue was). She not only prescribed the proper antibiotic, but also a cough suppressant so I can finally get some sleep, and even prescribed a probiotic to replenish the good bacteria. I cannot say enough about all of them! Even the front desk ladies and nurses! I highly recommend them if you’re looking for a forever doctor!

Dr.Mir is the best doctor I have met so far, she never rushes any appointment, she listens and spends time to hear what I have to say. It always feels like I am talking to a good friend when I visit her. She has always treated me with the right medication and she is very careful about not prescribing medication if it is not needed.

Unlike a lot of physicians who are in and out, Dr Zahir spends time with his patients. At my recent visit I had 20 minutes of his undivided attention. He shows a genuine interest in you as a patient.

Excellent customer service. The front office assistant s greets you and they are professional. The nurse is friendly and professional. I had lab work and the technician is professional and knowledgeable. Dr Zahir is professional and attentive to your needs. He referred me to a specialist for my needs. I truly recommend this professional medical health care provider. I live in Burke and I drive out to Reston to see him. He is the Best!
Awesome Dr! Very kind and always takes the time to listen to you! Only Dr I trust. I have often traveled back cross country during trips, just to see him.

I'm lucky to have a doctor like Dr. Zahir as my physician. Managing my health has become easier since I discovered him and his practice. He's knowledgeable, listens with attention, patiently answers my questions and, after every visit, I'm left with this feeling that he cares about my well-being. His front office is easy to work with and flexible.

I couldn’t ask for a better primary physician. Dr. Tarique exudes knowledge and efficiency. When you’re in his presence you just have a sense that you’re in good hands. The staff around him is courteous, professional and sincere. Just a great experience every time you visit.

Great visit! I really appreciated the visit. I felt heard and appreciated. My only point of concern is that she recommended a weight loss program within the doctors office because I’ve gained weight rapidly, I didn’t really like it.

Both me and my husband are patients at Prosperity Medicine and are thrilled with our care. Dr. Mir is compassionate, takes her time and is willing to think outside the box. Most importantly, she’s patient and listens to her patients. Dr. Zahir treats my husband and is very similar. They are both excellent doctors with positive attitudes which makes their appointments much more enjoyable. They really go above and. Ruins for their patients. Highly recommend.

I called because I was exposed to COVID-19. My primary care physician gave me their number as a place where I could get a rapid test. I spoke with Antione on the phone. He gave me great advice and set my mind at ease. He was reassuring during a very stressful time, when it was difficult to get answers from anyone else. Thank you Antione!
Phil Jones

Incredible service. The staff and doctors are incredibly helpful, and informed. I am a normal healthy guy but this doctor despite my good charts helped identify a fatal issue, based on a small symptom which while not a problem was connected to a potential fatal problem. He pulled a medical team of specialist to address the issue and quickly get me back to normal. Not kidding when I say he saved my life. He listens thinks about what he sees and you say then helps develop to build a plan to get and keep you healthy. One of the best Primary Care Doctors I have ever had!
