In August, I was rushed by ambulance to the INOVA Fairfax Hospital VA Emergency Room. While the ER physicians were working to diagnose the condition Dr. Sager, surprisingly, called my cell phone. While my family and I were talking with him the the ER surgeon appeared in the room. Dr. Sager was available to consult with her. All worked out well and I was soon released. It meant a lot to me… 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.

Testimonials from patients of Dr. Sager
My husband and I were patients of Dr Sager before he joined MDVIP. My husband was a bit wary of the expense of joining, but I convinced him that we'd need to continue with Dr Sager as we aged. My husband was already beginning to show signs of forgetfulness and I knew I would need a doctor who would advise me about my husband's condition. That turned out to be so true: About a year… See more
I can't say enough good things about Dr. Sager. I have been his patient for many years. He has always taken the time to listen to me, has cheered me up when I needed it, answered my questions, and taken care of my problems himself or referred me to specialist.
When I broke my foot recently on a Saturday and went to an emergency room, Dr. Sager called me right away to check on me.… See more
My husband and I have been patients of Dr. Sager for many years, including the time before he was a participant in MDVIP. We decided to make the move to MDVIP with him because we trusted his advice and knew he'd be helpful to as as we aged. That absolutely turned out to be the case: my husband had a stroke and later a pulmonary embolism. He also developed dementia and had to be moved to a… See more
Both of us (spouse and I) got covid and had a long conversation about it on the Saturday before Christmas. Dr. Sager was available despite the timing and was able to prescribe Paxlovid for us both and everything came together since our usual pharmacy was unable to get it in time so they kindly did the calling around and we were able to get it at an even closer pharmacy.

I will keep this short. A little over a year ago I was diagnosed with colon- liver cancer. Dr. Sager did a superlative job in coordinating my care in the areas he was (and still is) responsible. He has done a fine job up to now and I am highly appreciative of this.
Dr. Sager and his Staff - Thanks, Neil
I have been a patient of Dr. Sager for many years. He is always available when you need him, returning phone calls and/or responding to emails promptly. When he responds he gives you the science behind it as well as options that are available. His newsletters have always been good, most recently when he was explaining the COVID boosters, Flu shot and different scenarios on RSV. He… See more
My wife and I have been fortunate to have Dr. Lewis Weiner as our primary physician for over 15 years. Dr. Weiner is outstanding at diagnosing the cause of problems and recommending effective solutions as well as helping to implement good healthy living ideas and goals.
Equally important, his positive attitude allows for a COMFORTABLE, EASY and THOROUGH two way discussion… See more
I've been a patient of Dr. Sager for close to 10 years now. One of the things I admire most about him is his bedside manner and the way he puts people at ease. Appointments are both educational and I walk out feeling better for having seen him. He provides peace of mind to my medical questions and issues and that is much appreciated. I consider him not just my doctor, but a trusted… See more
I really appreciate all the years I've been under the care of Dr. Sager. He has always been my trusted physician and friend. He has seen me through many years with lots of laughs along the way. I consider him a true blessing.
