Meet 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.

Great doctor very knowledgeable and kind. As for the office manager who was there, she has sinced left. Please dont let someone like that who was clearly not a representation of the Dr. Greogory. He is good decent guy and a great doctor. And he will contact you back when you need him too and he is courteous too. It is very hard to find a good doctor and one that will work with my crazy work schedule. I am sorry you had a bad experience.

Dr Gregory is a wonderful doctor ready to help at all times. Have called him from out of town while traveling many times and he not only was responsive but called the next day to follow up. 5 stars in knowledge and compassion.

Worst bedside manner I’ve ever witnessed. It saddens me to know unprofessionalism slides under the radar like this.

Dr. Gregory has taken exquisite care of me during this last year of my life, given that I had an avalanche of serious health issues occur. He caught something very important that I thought was flu, which was detected on a CAT scan he sent me to have. He has referred me to specialists when needed, and has responded to many phone calls, over the weekend and evening when need be. I wound up in the ER twice, where he sent me: once with Covid and once with Diverticulosis. Several other things needed immediate attention, and he never failed to call me back or pick up the phone. He never sounds irritated or bothered, which I so appreciate when I need to call him after office hours. Without an MDVIP doc this year, I would have been in terrible trouble. Hips, back, bones, gut, and a needed hysterectomy were some of things he tended. Doc G is warm, gracious, serious when necessary, and very glad for health and life improvements. He's a great diagnostitian, and figures out solutions rather quickly. He celebrates some of my professional successes as well as health things. And, Dr. G listens to me and believes me to know my own body. That is huge!!! When Dr. Gregory first posed becoming an MDVIP doc and would I/we follow him, I said No. After two months, I tracked him down and said "Yes." My husband followed months later. We love and appreciate Dr. G very much. I have recommended him widely, even though I think his practice is full. He is a gem, indeed! I hope he never retires. :-) I sent this description with profound gratitude and joy. Nicki McClusky

Weekend Support
from Patricia in MO • March 14, 2024
It wasn't the first time I reached out to Dr. Gregory on a weekend and I don't want to make a habit of it. But recently, on a Sunday, I tested positive for Covid. Knowing Paxlovid is typically only prescribed in the first days of onset I didn't want to miss the window to use the drug. Dr. Gregory was in a meeting and could not take my call right away but he did text and then followed with a call Read more...
I'm so fortunate to have found Dr. Mark Gregory long, long ago
from Sandra in IL • March 13, 2024
I found Dr. Mark Gregory years and years ago (probably in the mid 1980s) after a year of unsatisfactory HMO care, especially the obvious indications that “my” doctor was less than thrilled to have me as a patient, one whose lifelong struggle with weight would never be a “success” under his care. Once I emerged from my HMO plan, I began asking friends for doctor suggestions and one was for Dr. Read more...
Dr. Gregory always makes time for me
from Helen in IL • February 29, 2024
He always makes time for me and respects and tolerates my feelings about medications. His referrals have always been good and understanding thus far. He is a special human being who always cares about me. And has a great sense of humour, most important! He is the best.
Patient of Dr. Mark Gregory
from Phil in MO • February 13, 2024
Whenever we have a need to speak with Dr. Gregory or need medical advice or a prescription filled, he always answers our texts or phone call to his cell phone almost immediately which we appreciate very much and is consistent with what a concierge doctor is supposed to do. He is very thorough in his examinations and provides the right advice.
