Dr. Marie Hollis
As a board certified OB GYN I enjoy providing quality health care for women in all phases of their lives.
Women’s health care is a very personal experience and I strive to provide comfortable and informative care to
all of my patients. I moved to Greenville when I was 5 years old. After attending college at Texas A&M
University Commerce for my undergraduate education I went to medical school at Texas A&M University and
did my OB GYN residency in Tulsa, Oklahoma. After residency I wanted to come home and be near my fam-
ily so I moved back to Greenville. My parents, 4 brothers, and 2 nephews are proud to be Greenville natives
and I plan to live here and serve the community for many years.
