Testimonials | North Bethesda Primary Care

At North Bethesda Primary Care, we’re dedicated to delivering thorough, compassionate, patient-centered care. We treat you like the unique individual you are. Because we’re unlike other medical clinics in this regard, we often hear from patients who are pleasantly surprised at how efficiently and effectively we’ve been able to help them – and just how much better concierge care can be than the healthcare most people are used to. We are proud to share a few of those patient testimonials below.

“I recently underwent the most detailed annual physical examination of my life. Dr. Zeki delved into my medical history and current health status, and also provided explanations for specific medications and lifestyle modifications, making it easier for me to adopt them. Prior to this appointment, she assisted me in managing a knee injury and arranged consultations with specialists. My wife and I are extremely grateful to have her as our primary care doctor.”

~ Christopher S., North Potomac, Maryland

“Dr. Possner is a rare gem of a physician. He really listens to my concerns and asks lots of questions so that he understands me and my health. The reason I really trust him is his coordination with my other physicians. He reaches out to get other reports so he can get a clear, big-picture view of my health. I have met many physicians in my work and personal life, and I can say with confidence that Dr. Possner has my best interests at heart. He is someone I have full faith in to care for me.”

~ Mindy A., Rockville, Maryland

“Dr. Adam Possner is the most anyone could ask for in a doctor. He is incredibly thorough – never have I experienced a doctor who has spent as much time with me. He is highly responsive – I was blown away when I had blood drawn late Friday and received a message from him early Sunday with the results. He is well-connected and secured specialist appointments for me in no time at all. I can think of nothing negative to share and encourage anyone seeking a gifted, personable, empathetic, and truly caring doctor to choose Adam. He is simply the absolute best.”

~ Elan B., Rockville, Maryland

“Dr. Dina Zeki is the epitome of what I wanted in my PCP. She is the most thorough physician I have ever had…. As a new patient of Dr. Zeki's, she carefully went through all the notes from my chart (I'm old, so there is a lot)! Going over prescriptions I had many questions and she had answers. I am impressed by the fact that Dr. Zeki was well versed about me from all the material sent to her. The first appointment was long, but it included a complete physical and various other work-ups. It was definitely time well spent. I am beyond happy to have chosen Dr. Zeki to be my very own physician. To have a doctor give you all the time you need is so important to me; and getting responses right away is such a plus. Better than having to chase a doctor! Dr. Zeki is a gift and she should be your doctor!”

~ Ellen W., North Bethesda, Maryland

“Dr. Possner is by far the most responsive doctor I have ever had. He listens, educates, treats, and most of all, he has time for you. He’s never rushed and incredibly thorough. I wrestled with some significant GI issues. You would think my GI doctor would’ve been able to provide a solution. Well, the GI doctor's solution didn't work. Dr. Possner's solution and approach is working, and I am regaining my quality of life. He is worth more than his membership fee. He's priceless. After being his patient, I wouldn't know what to do if I reverted back to 'cattle call, you don't matter medicine.'"

~ Kyle W., Clarksburg, Maryland

“I consider it a privilege to have Dr. Zeki as my primary care physician. Working with her is the best thing that I have ever done for my health. I highly recommend Dr. Zeki to anyone that I know who is looking for a highly skilled physician to oversee their healthcare and overall wellness. She is thorough, professional, and personable. It is obvious that Dr. Zeki’s priority is to provide best-in-class healthcare for her patients. I am grateful to be under her care.”

~ William H., Clarksburg, Maryland

“Dr. Possner is a very talented, kind, and thoughtful physician. He helped me begin to solve a chronic health condition that multiple doctors had been unsuccessful in addressing, because he takes the time to think through problems systematically. He responds quickly, clearly, and thoroughly to emails and questions, and efficiently coordinates care with specialists. He cares personally about his patients' well-being. He is really everything that I looked for, but never found, with doctors in the past.”

~ Tom W., Takoma Park, Maryland

“I am quite impressed with the services I receive from Dr. Possner. Concierge medicine is a trend that has been gaining momentum over the past few years, and my experience has been absolutely phenomenal. I personally own several practices, and the traditional office practice has several pitfalls: problematic insurance reimbursements, lack of personalized patient attention, and a high volume of patients that most offices must manage in order to achieve financial stability.

The concierge model is the complete opposite. Dr. Possner is an extraordinarily perceptive and insightful physician. Never before have I been so privileged to be under the care of such an attentive doctor. My first physical was remarkably thorough – it lasted two hours. Dr. Possner took a proper history, performed an assiduous examination, ordered the necessary tests, and we explored what was necessary and appropriate for my age and needs. I am pleased with Dr. Possner's expertise and quality of service; I strongly recommend his practice.”

~ Nesly C., Bowie, Maryland

“Dr. Possner is an exceptional physician. He has that rare combination of diligence, skill, and impeccable bedside manner. He is thoughtful, respectful, and warm. His practice embodies the true, but often lost, spirit of primary care, which is to know your patient well, coordinate their care with all professionals involved, and treat you like a whole person instead of discrete sets of problems to be farmed out to specialists. He is especially gifted at working with medically literate patients who want to understand and be active decision-makers in their care, along with their physician. A treasure!”

~ M.H. via Yelp

“Dr. Possner has been our family doctor for several years now. We switched after having bad experiences and being unable to find a good, reliable primary care physician. Dr. Possner is knowledgeable, caring, and incredibly considerate with all of his patients. We have been incredibly pleased with the service and doctor availability. Being able to contact him while traveling has been invaluable. Oftentimes, Dr. Possner has been exactly right about what was wrong – even when I didn't expect it. We are moving to another state now and will really miss Dr. Possner. He is highly recommended!”

~ Michael G., Silver Spring, Maryland

“I've been seeing Dr. Possner for seven years. He is the best doctor that I've seen in my life. He was first recommended by my sister who is also an internist. His training is excellent, too: he went to the University of Michigan Medical School and Johns Hopkins for his internal medicine residency, where he was chief resident. He listens well, asks good questions, explains his reasoning clearly, has a nuanced understanding of my personal medical case, and has excellent judgment.”

~ Nick K., Bethesda, Maryland

“Dr. Possner is definitely the best doctor I've ever had. I was on the fence at first about the idea of paying the fee for a concierge doctor, but I'm so glad I did because it's totally worth it. I've been used to big medical practices with rude, inattentive office staff, but everyone at this office is so nice. I've been able to get in super quickly every time. Once I even called when I was sick, and they told me to come right then. It's also obvious that Dr. Possner listens to and cares about his patients. Whenever I visit, I don't feel rushed. He explains my treatment options, along with pros and cons, so we can make a decision together. This is unlike other doctors I've had who just rush in, write a prescription, and then I have to Google everything later to know what's going on. I also really like that he answers messages super quickly. In the past, I've felt like I was bothering doctors if I asked questions, or I wouldn't make an appointment until things got really bad because I felt like I was wasting their time. Now, I feel totally comfortable asking Dr. Possner even about little things. I'm really glad I made the choice to start seeing him. It’s totally worth the money.”

~ Lisa F., Rockville, Maryland

“I became a patient of Dr. Possner after a friend told me what a wonderful physician he is. She was correct! Dr. Possner took the time and care to collect and read through my long medical history from many different specialists, and to question some of the prescriptions I'd been taking – unnecessarily, as it turns out. He's extremely thoughtful, careful, and responsive. He answers my questions through the patient portal immediately and called me immediately when I needed to speak with him. He's an excellent and caring doctor in every way, and I couldn't recommend him more highly.”

~ Marcia M., Silver Spring, Maryland

“I had the good fortune of being a patient of Dr. Possner’s for one year and what a wonderful experience it was! I wish I hadn't moved away, so I could build a long-term relationship with him. From the moment you check in, through every question, procedure, or healthcare need you have, the focus will be on you. This is the way medicine should be practiced! Dr. Possner is a caring, thoughtful, and detailed physician who takes the time not only to answer all questions/concerns but also to follow up with you throughout the year. Communication through the patient portal is efficient, clear, and speedy. I could not have asked for a better experience and hope I move back at some point so I can be a patient again!”

~ James G., New York City, New York

"Dr. Possner is a fantastic physician. In addition to being extremely knowledgeable, he has taken an extraordinary amount of time to get to know me, study my prior medical history, and to do whatever is necessary to ensure he provides me with the highest quality of care. He communicates extremely well, and really takes the time to make sure he answers all of my questions and that I understand his reasoning. He also goes the extra mile to truly coordinate my care – speaking regularly with specialists and making sure that nothing falls through the cracks. He's the first doctor I've ever seen that proactively checks in with me just to see how I'm doing. It's really another level of medical care."

“I found Dr. Possner simply by doing a Google search, and I had no point of reference for him. I am so glad (and lucky) that I found him. He literally saved my life within the first week of meeting him. To summarize, he is fantastic, a true diagnostician, a healthcare quarterback, and a fantastic person. All-in-all, I would recommend that anyone looking for a concierge physician visit Dr. Possner. Here are more details about my story:

I have been a type 1 diabetic for more than 35 years. Despite my condition, I am in relatively good health. I played college football and baseball and am very active. However, over the past few years and months, I had been feeling awful. I had trouble walking up and down stairs. I could not even go for a walk, let alone a run, because I was always out of breath. I figured it was due to stress. I had an endocrinologist who had come up with zero possible areas of concern for the past five years. OK, fine, but I still felt bad, so what do I do?

I went to see Dr. Possner and before my credit card payment had even been processed, he ordered some blood work and had a few ideas as to what might be ailing me. First and foremost, he compared my previous blood panels and realized that I might have an incredibly difficult-to-diagnose condition called pernicious anemia. I ended up in the hospital for a blood transfusion within the first week of meeting Dr. Possner and ended up with a prescription of B12 injections.

Now I feel amazing! I am back to working out four to five times a week. My hospital visit was about two months ago, and the recovery was fantastic. It also turns out that I have another autoimmune deficiency, which Dr. Possner found, and I am being treated for that, as well. I had been passing out and essentially close enough to death's door that I could not function. Dr. Possner figured out how to treat the symptom first (so that I could breathe and walk around) and then began treating the disease (so that I could exercise and live normally). Now I am feeling great, and I owe him a huge debt.

Anyone looking to feel better should speak with Dr. Possner. I can give no better advice than that. Again, none of my previous three endocrinologists had diagnosed my two conditions, and Dr. Possner figured them out in about a week, which is truly amazing.”

~ Petey K. via Yelp

“I was introduced to Dr. Possner by a good friend. There are not enough words to describe how thankful I am for this introduction. From the first meeting I had with Dr. Possner, I knew things would be vastly different and that I had found someone who would have a profound impact on my health. My first appointment was the longest time I had ever spent with a doctor. My appointment was 2 hours long. Dr. Possner had fully reviewed my medical records and engaged me in thoughtful conversation about my medical history. I left my initial appointment with a feeling of empowerment over my health that I had never really felt before.

Little did I know the impact Dr. Possner would have. I was on vacation and had an acute UTI. It was after business hours, but I was able to call the office and get Dr. Possner. I walked him through my symptoms, and he immediately called in a prescription for me. Because he had such knowledge of my history, it was easy for us to communicate and talk through my symptoms. He checked in on me via email through the client portal several times over the next couple of days to ensure I was OK. The fact that I was in a remote part of a different state and I was able to call and speak with him saved me the stress and hassle of locating a nearby urgent care facility.

Dr. Possner has made several recommendations to other specialists and doctors, all of whom have turned out to be amazing. His referral goes a long way with each specialist I have scheduled an appointment with.

I can't recommend Dr. Possner enough; he's a great listener, thoughtful, caring, kind, and you can tell he truly loves what he is doing. His follow-through is simply amazing.”

~ Christine S. via Yelp

“My wife and I met Dr. Adam Possner when our other doctor retired. We were looking for a doctor who was young, highly qualified, and accessible. After interviewing him, we did not need to interview any others – we knew right away he was the one. During the several months we have been with him, we had medical problems that really put him to the test, and we have been so impressed! Medical problems are no fun, so we are thankful to have a doctor we trust to guide us with whatever is out there to help with them.”

~ Marvin C. via Google

“I started with Dr. Possner about a year ago. I have a rather complex set of medical conditions/issues, and I needed to find someone to assist in the overall management of my health, as well as provide ongoing care. I went to several different doctors but could not find one who offered the level of care I was looking for – until I found Dr. Possner. I can say without reservation that he is one of the best doctors I have ever had. He is very attentive, very active in your care, and has exceptional staff. He consistently goes above and beyond and ensures that all my doctors are consistently updated and kept in the loop. He takes his patient care very seriously and has a strong network of other doctors who are top in their field (if you happen to need a specialist). He has a strong depth of medical knowledge, as well as the initiative to learn more if he feels it will help with your care. He’s a true Top Doc.”

“In 2017, I went on the search for a new primary care physician. Growing up, I had the same pediatrician from age 6 through 18 (Dr. Gold). I remember having such a positive relationship with my pediatrician and appreciated his oversight and commitment to my care. I grew up with a multitude of medical issues ranging from muscular eye issues to allergies, asthma, recurring pneumonia, pertussis, Cushing's disease, and every child's favorite reason to be at the doctor's: a broken arm from falling off my bike! Whether I wanted to be or not, I was a regular at the doctor's office. When I was 18, my pediatrician retired and told me it was time to move on from the pediatrician's office and see a "big boy doctor" now. From there, I went to a primary care practice that my parents went to. There was an attention to detail that was missing.

At 27, I found myself working for a government contractor based in Rockville and began searching for a local physician. I came across Dr. Adam Possner. I won't suggest that the concierge model will work for everyone, but it is by far the best experience I have had with a primary care physician in my adult life. Dr. Possner is an assertive communicator who has excellent bedside manner, pays attention to detail, and is always ready to help. He is extremely knowledgeable, thoughtful, and puts forth an extra level effort that I truly appreciate. I have absolutely no hesitation in recommending Dr. Possner.”

~ Adam B., Washington, DC

“Dr. Possner provided some of the best and most personalized medical services I have experienced. I recently had a health scare, and Dr. Possner took the time to help me using a holistic approach. He quickly reached across his extensive network of doctors and healthcare practitioners to meet my needs. These weren't random people he had to look up in a directory. They were people he called up directly, on my behalf, while I was still in his office. Each service provider Dr. Possner connected me with worked with him to improve my health. He remained engaged every step of the way, taking a personal interest in my progress.

He not only has great resources, he is also incredibly smart. When asked questions, he was able to provide answers and guidance that included alternative perspectives, at a moment’s notice. He very rarely had to get back to me to answer a question. His personality, professionalism, network, attention to detail, and patient relationship management are top notch.

I come from a family of doctors and grew up around hospitals, so I know a thing or two about doctors. Dr. Possner is a doctor's doctor in that he is well-connected and professional. He also has the qualities patients seek – personability and intelligence. I highly recommend Dr. Possner if you’re looking for a primary care physician. I welcome any opportunity to provide any additional insight to help a fellow patient in need of a new doctor.”

~ Steven F., Gaithersburg, Maryland

“Any time a friend and I would talk about anything medical-related, he would go on and on about how Dr. Possner was the best doctor he's ever had. Eventually, he convinced me to schedule a meet-and-greet. I wasn't sure if a concierge doctor would work for me. But, after being his patient for a little over two months, I can say that Dr. Possner is easily the best doctor I've ever had. He is extremely knowledgeable and eager to help. It's very easy to get in touch with him by email or through the online portal. It's refreshing to find a doctor's office that embraces technology. He's been able to treat me for a wide range of issues. For the few issues he couldn't help me with, he went out of his way to find me highly recommended specialists. If you're looking for a new doctor, I highly recommend Dr. Possner!”

~ Chris F., Reston, Virginia

“Dr. Possner is attentive, detail-oriented, has excellent bedside manner, and takes the time to listen to you. He is readily available, and quickly responds to queries at all hours. The physicals are thorough, and regular visits aren't rushed affairs. Getting appointments same day or next day is not a problem. I can't speak highly enough of Dr. Possner. Once you have an opportunity to see a doctor in this care model (concierge/personalized), you won't ever want to go back.”

~ Yamil H., Gaithersburg, Maryland
