My Philosophy and Approach to Wellness...

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.

Testimonials from patients of Dr. Gregory

from Caroline in MO March 12, 2020 for Mark H. Gregory, MD, FACP

I’ve never had a doctor call to wish me happy holidays and to remind me to remember our troops. My dad served in the military for 27 years. My mom and dad are buried at Arlington National Cemetery.
Dr. Gregory is a kind, thoughtful and compassionate physician. Thank you for your kind care and for reminding us that while we are lucky to have great medical care, many sacrificed so we could… See more

from Laura in MO March 12, 2020 for Mark H. Gregory, MD, FACP

In a time when the medical system is challenging enough to navigate, having a physician who actually takes the time to get to know you on a personal level is so refreshing. Dr. Gregory took the time to truly listen to me, and asked thoughtful questions about my health and goals for my well being. More importantly, he is accessible and engaged - to the point when I call, he knows me personally… See more

from john in MS March 5, 2020 for Mark H. Gregory, MD, FACP

Dr. Gregory has always been friendly and informative with me. We do share similar interests but I feel he treats everyone equally well.
I never have felt he was uncommunicative or anxious o skip ahead to the next patient. I have full confidence in his professional opinions
and advice he gives. Both my wife and are extremely happy with our choice of physician.

When I called you from out of state and was in pain from breaking my nose in a fall, you told me exactly what to do and for how long. The ER doc said to take Tylenol, which did absolutely nothing to help.

If feels so good to know that I can reach you, no matter where I am---to get the best care from my Doc who knows me well. Also, if I get sick in town, you're only a short… See more

I cannot put into words what Dr. Gregory being my physician means to me. I trust him implicitly for my medical care. His immense knowledge, his caring manner, his tireless response to any questions I have whether it be during office hours or not is truly beyond any other experience I have had with the medical field. I am constantly amazed with this man’s dedication. He truly is one of a kind… See more

from Rita in MO March 20, 2018 for Mark H. Gregory, MD, FACP

Dr.Mark Gregory, your care for our family has been very appreciated. The time you take to listen, explain and prescribe is priceless. You do much more than a usual doctor would do.
As an example: The time I texted you about my sister's allergy and my brother's cancer, you were quickly returning answers to my questions. This outstanding support made me feel like you were… See more
