About Mark H. Gregory, MD, FACP
Being a physician is a great honor. I do my best to practice excellence in medicine, and I enjoy it. The most important tools a doctor has are time and the ability to listen. I have extra time to spend with patients listening to all their concerns – big and small. I also have time to help patients navigate through today’s complex healthcare system. I consider myself a friend and an advocate for my patients, as well as their trusted doctor.

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.
