Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Simply the Best
Dr. Dempsey is the most thorough doctor I have ever seen. He never rushes through an appointment. He listens to your concerns and really cares about helping you improve your quality of life. His forward-thinking has allowed me to live my life for past 33 years without the long- term complications associated with Type 1 Diabetes. He is simply the best endocrinologist. And his front office is a pleasure to deal with as well. He schedules appointments in such a way that there are never long waits to see him in his waiting room.

The best of the best
As a physician, I am very careful about whom I refer patients to. When I was first looking for an endocrinologist for my patients, I asked a colleague who he thought would be a good endocrinologist to refer to. He said: 'Michael Dempsey. He is not just the best endocrinologist in the area - he is probably one of the best endocrinologists in the country'. Now, as both a patient of Dr. Dempsey and a referring physician, I have to say he was right. Dr. Dempsey is very thorough, extremely knowledgeable, and a compassionate doctor. I highly recommend him to anyone in need of an endocrinologist.

Best Endocrinologist
Dr. Dempsey is the best endocrinologist I’ve had and helped me to lower my A1Cs and improve my time in range. I feel that he puts great effort into always making me feel happy and healthier as a patient and doing his best to assist me with whatever I may need. I am really able to count on him as my endocrinologist!

Excellent endocrinologist
I have been going to Dr. Dempsey for the past 3 years. He is an extremely caring physician. He listens to understand my concerns. He is patient with my questions. He is thorough, thoughtful and extremely knowledgeable. Mostly, however, he has been a steady advocate for me during my health care journey.

Best Doctor I Have Ever Had
Dr. Dempsey is the best doctor I have ever had. Since our first visit he listened so he could best understand how treat me. He is very knowledgeable and shares it to help his patients better understand their conditions. He also takes the time to get to know me as a person and not just a patient. We chat about the Nationals or any other sports news. He knows about my family and various stressors in my life and always takes the time to ask. He even shares a bit about himself and family as well. He is truly a great doctor and even more importantly a great person!

Best Doctor I've EVER been to
Dr. Dempsey is the most thoughtful and thorough doctor I have ever seen in my life. He takes his time with you at each and every appointment to go over you medical/social history in his office before he performs a medical evaluation. Then he takes you into an exam room and again, takes him time with you to thoroughly evaluate your medical conditions. He is extremely knowledgeable and kind. I HIGHLY recommend him.

Observant expert, thoughtful
I found Dr. Dempsey to be empathetic, observant and highly qualified in his craft. He last saw my 90yr+ father a year ago and was able to deduce his complexion had paired meanwhile. He also mentioned that my father often talked of his children during past visits, something I wouldn’t have know based on my fathers stoic demeanor. I was able to deduce by the Dr. Methodic crawl through labs and in office vitals that he wasn’t one to miss clues , like a veteran detective he takes his efforts and patients well-being seriously and expertly.

Having known Dr. Dempsey for approximately 5 years, I have found him to be one of the more knowledgeable doctors I’ve ever talked to. Dr. Dempsey takes into account all of your medical issues, before making a recommendation. He is very clear when asking and answering questions, and encourages a patient’s input. He is also respectful of a patient’s time. As a result, there is almost never a wait, which is very rare in the D.C. area. I would highly recommend Dr. Dempsey.

Issue with high T4 so went to Dr. Dempsey for further examination. It was complete and educational in how he described what could be happening. Spent time explaining and drawing upside down...not sure how he did that so well.

I have been a patient of Dr. Dempsey for 31 years. He is awesome and tells you the facts. I’ve lived with Type 1 diabetes for 52 years. Because of Dr. Dempsey working with me over the years I have stayed extremely healthy. I was fortunate enough to be his very first pump patient. Dr. Dempsey stays on top of his research and he keeps me informed of what is new out there. At this time there is no cure for diabetes, but working with Dr. Dempsey has enabled me to have minimal complications and lead a “normal” life. Thanks Dr. Dempsey.

Doctor Dempsey was extremely thorough analyzing my medical history and suggesting a change in medications. My A1C has been much better under his supervision. I send him Libre two week glucose reports. He always responds in the same and makes suggestions regarding changes in my medications. I would recommend him to anyone that's suffering from diabetes.

I have been a patient of Dr. Dempsey for many years. He is kind, understanding, and very knowledgable. He's always willing to try something new, tackle a problem with a novel solution. He also makes himself very available to email and calls when needed. As a type one diabetic, he has helped me reach my best A1c and by far my best periods of control, after a more difficult period prior to seeing him. Of all the endo's I have seen, he is by far my favorite.

I have been a patient of Dr. Dempsey's for some 20 years. In all that time I have found him to be an excellent doctor. He understands diabetes and how to deal with it. He has put me in test groups he has managed and always been there for me. He returns calls and is very professional. His office is well run with no long waits for appointments. I highly recommend him.

It's easy to see why Dr Dempsey has so many great reviews. Dr Dempsey has helped me a lot. He has been courteous and kind since I began seeing him 2 years ago. My internist referred me because of diabetes and thyroid problems which another endocrinologist couldn't solve. It was driving me crazy. She said Dr Dempsey would be her first choice if she ever needed an endocrinologist. She also said she had sent her husband to see him, which was good enough for me! As others have written, Dr Dempsey listens, and is non-judgemental. My control has never been better. He has a nice bedside manner and is very prompt. He always calls with lab results, saving me unecessary appointments and time away from my job. I recommend him highly.
