Dr. Sager is just the best. I have been going to him for years before he joined MDVIP and my decision to join was based exclusively on retaining him as my PCP. Even before MDVIP Dr. Sager spent lots of time with me discussing not only my specific health issues but also getting to know me, my job, my hobbies, my priorities, etc. When I visit him it is like going to see a long-time friend who… See more

My Philosophy and Approach to Wellness...
I have practiced internal medicine in Reston for over 30 years. I was one of the founding physicians of Reston Hospital. As an internist, I treat conditions ranging from hypertension, diabetes and hypothyroidism, to the common (and sometimes not so common) cold. I have also combined my NASA and FAA engineering experience with my medical education in a different way; I am a Senior FAA Medical Examiner, certifying pilots as medically fit to fly. Throughout my medical practice I have always spent a large amount of time with my patients at every visit. My MDVIP-affiliated practice, often compared to a concierge medicine practice, also offers conveniences like same- or next-day appointments. Changes in the practice of medicine have forced doctors to squeeze more patients into shorter periods of time, which I choose not to do. MDVIP allows me to continue to practice medicine in the manner I feel it should be done.

Dr. Sager is very attentive and prompt regarding any medical condition or complaint. Recently when I had a stomach issue, he wasted no time in intervening with a gastroenterologist so I could be seen promptly. I was then scheduled promptly for a test, a diagnosis was made, and the problem was addressed and resolved. I cant speak highly enough of Dr. Sagers prompt attention and intelligent… See more
Dr Sager has been my primary care physician for over 30 years. Not only is he (and his staff) knowledgeable, professional, and experienced, but every patient is treated like a member of his family. If your looking for a dedicated physician, you can do no better than to choose Dr Dennis Sager.
Dr. Sager cares very deeply about all of his patients, always appears to have read up on several recent medical studies, and is not afraid to say I'm not sure, I want you to see a specialist when that response is appropriate. I feel lucky to have him as my primary care physician.
MDVIP represents the way healthcare should be managed. I have strongly recommended the service to family and colleagues, who are in the process of following up on their own to join. Going back to old style health care, where the physician really gets to know the individual plan member over time and circumstances, is the only way primary health care should be practiced.
I have been a patient of Dr. Dennis Sager for about 25 years and like him v.v. much. He is v. knowledgeable, has a great memory, and appears to be medically up-to-date. I v. much like his direct, no-nonsense approach to medical issues, and his wonderful sense of humor.
The only reason I joined MDVIP was to retain his service. However, I have been v. fortunate to have few health… See more
I became a patient of Dr. Sager when I was a relatively young man; this year, I'll turn 60. Dr. Sager has seen me though countless routine medical checkups and a few more vexing issues. I assume all doctors are experts in their field--and, to my layman's eye, Dr. Sager is certainly no exception. But I especially value his exceptional ability to listen, to explain, and to help me… See more
