What Members Are Saying

My wife Carol and I have been exceedingly pleased with our continuing relationship with our primary care physician, Dr. Han Jong (John) Koh over these past several years. Dr. Koh has been exceptionally attentive and caring in providing us with outstanding medical care and health advice. We have been especially gratified with his attention to detail and persistence in following our various health conditions, as well as his responsiveness in dealing with several "pop-up" medical challenges from time to time. After spending 30 years' service in the U.S. Air Force where we relied on the extensive - and effective - military medical system for our care, we especially like the fact that we have been able to rely on Dr. Koh for our continuing care, month after month and year after year, rather than a different military doctor each visit.

John

Patient of Han-Jong (John) Koh, MD

Grateful for Dr. Koh and his staff for being available and receptive to my questions and supporting me on more than one occasion when I was away on travel. Prescriptions for medication while I was out of town for managing Covid, another time I was able to get a prescription on short notice for antibiotics before leaving for a trip outside the country. But right from the start Dr Koh was an ally by giving me great advice on diet and exercise to prevent the need for medication for cholesterol. I have never had to wait, feel rushed or uneasy asking questions at Dr. Koh’s practice in Leesburg, Va. My goal is to focus on best health prevention of disease and ailments and seek best treatment actions for those times when needed. I have an optimal team supporting me in that goal and I am gratefull!

Patient of Han-Jong (John) Koh, MD

In the summer of 2021, I finally got my wife Nancy to call our MDVIP doctor, Dr. Han-Jong (John) Koh for an evaluation of abdominal pain that she had experienced and not for too many weeks not acted upon. He immediately made room for her in his busy schedule and after seeing her arranged a same same-day scan, the results of which could have take days to obtain. Instead he followed up and obtained the results within hours. He call Nancy as we were attending her hair appointment in Washington D.C. that very day. He told her that he suspected she had cancer and told her to immediately report the local Loudoun hospital ER for further assessment. He called ahead and lined-up (greased the skids) with admittance, a surgeon and an oncologist. She did so and we embarked on a Stage III Ovarian cancer journey now in it's 31st month and still working with Dr. Mike Bevers of MD Anderson Hospital in Houston and Dr Ajay Dar of Virginia Cancer Specialists in Loudoun Virginia, That follow-thru by Dr Koh has earned him our respect and appreciation ... and a key reason we remain with MDVIP, when we have other options and need pay nothing with Military Tricare for Life. His responsiveness and redirection to other specialists make our being an MDVIP patient of his a no brainer. Thanks Dr. Koh.

Frequently Asked Questions

Doctors who operate in the MDVIP models typically see far fewer patients than traditional primary care doctors. That gives them more time to develop deeper doctor-patient relationships that can lead to better outcomes. They can also offer conveniences that most primary care doctors can’t, including same- and next-day appointments. They’re available after hours for urgent matters. And they have time to focus on prevention. That focus begins with the MDVIP Wellness Program, which patients pay for with their annual membership fee.

Most MDVIP-affiliated primary care practices accept insurance (your physician can tell you whether they accept your specific insurance plan). Your annual fee pays for preventive care medical services that insurance usually doesn’t cover (e.g., advanced diagnostic testing and screenings). Your MDVIP-affiliated physician will continue to bill your insurance and charge copays, co-insurances and deductibles as he or she currently does for other medical services like sick visits.

MDVIP makes wellness and prevention easier by providing your physician with innovative tools and technology. MDVIP supports your physician’s practice and seeks to eliminate barriers to a positive healthcare experience. Your doctor will determine whether and how to incorporate these tools at his/her discretion.

Dr Koh has been there for us when we needed help. The first was when my husband became ill when we were out of town. He moved quickly to help. My husband avoided surgery and we got back home before COVID closed air travel. Another time he helped me when I called him on the weekend, going to the office on his family member’s birthday.

I am a patient with Dr. Koh and I have worked with him on my mom's care. Dr. Koh and the staff have always been helpful, empathic and knowledgeable. My mom had many complicated medical issues and Dr Koh was always very thorough and explained things to not only my mom, but to me. The staff always worked with us on specialist. I hesitated to sign up with MDVIP when his practice switched, however, it has truly been the best thing for me and my family. I trust them with all my health needs. They truly partner with you to improve your overall health. The whole staff is 5 star.

Dr. Koh is such a kind and genuinely caring soul. We passed by him in the hallway today as we were on our way to Dr. Akhtar for a joint replacement consultation in his Leesburg office. Since we had entered the building from the wrong side, it was a long walk to the doctors office for my mother. Dr. Koh not only have us great instructions on how to get to the doctors office, he also helped my mother get a wheelchair since she was going to have a hard time walking. He then escorted us to Dr. Akhtar’s office himself along with a staff member. He still had his lunch in his hands and didn’t rush us at all. The world needs more people like him.
I wish you a blessed life, Dr. Koh!

Dr.Koh has given me a better quality of life. When I first went to Dr. Koh my blood pressure was out of control, my diabetes was out of control along with my triglycerides. Within 3 months everything was under control. Dr. Koh is such a compassionate Dr. Who always has my best interest first and foremost. My quality of life is greatly better and also has extended my life thru his knowledge and skill.I appreciate everything he does for me.

This physician and practice deliver top notch care. For me I have some complex health issues and need a group that are up on my medical issues and treatment options. While it is more expensive to join MDVIP it is well worth the level of care, expertise of the medical staff! They look out for and help with total care not just the mundane care. Would highly recommend this physician and practice to anyone that is looking for great care!

Dr. Koh May be one of the most brilliant physicians that has ever cared for me. He is able to connect the dots between remote contributing factors, genetics, lifestyle and not only make sense of it but give you a plan to get healthier and stay that way.

Always available, he goes the extra mile for his patients- checking charts and notes to ensure he gives you the best medical advice.

Dr. Koh is kind and a great listener; we could not be happier with our choice of MDVIP physician.

Dr. Koh has been my main physician for over 10 years and I am hoping he will be my main physician for at least another 10. In the beginning, he recognized that a persistent cough that I had for a couple of decades was due to acid reflux, even though my episodes of reflux were very infrequent. The cough was cured with Nexium and I now have periodic screenings for Barrett’s Esophagus.

Later, Dr. Koh coached me to reverse and avoid diabetes by reducing my A1C from 7.2 to 5.7. (more activity, weight loss, and a switch from Lipitor to Pravastatin) In addition to his help with the two potentially major problems, we have a dealt with several minor issues that have helped me maintain my health.

Dr Koh is in my opinion a first class 'Battle Captain' for managing really vital health issues ... especially cancer. He does not possess a weak ego, but is willing to engage even over disagreements about his staff ... and then make it right. Most doctors that I have known in some 70+ years would just walk away from a controversial issue. Not Dr Koh. He was just as tough as I am (an Army Ranger) and just immediately dug deep and solved the issues with an extraordinary commitment of time, expertise and energy. I greatly respect him for that. IMOP, a patient won't go wrong with Dr. Koh ... if the patient will just explain the issues/concerns they have. His response to my angst over his staff's support was admirable. I will stick with Dr Koh. He continues to help keep my wife and partner of 58 yrs alive. He explains what the many specialists do not. He is my valued medical researcher and interpreter. Thanks Dr. Koh for helping me keep my wife alive for as long as she continues to wish to fight her cancer ... now 42 months.
