About Grapevine OBGYN

Timothy J. Rost, M.D.
Being an Obstetrician/Gynecologist affords me the privilege of having long term relationships with my patients. It is rewarding to me to walk along and partner with patients through the different stages of their lives - and even in their children's lives. I like to think that I bring a few skills "to the table" that are more than just medical knowledge - a father of five, an elder at my church - things that help me serve my patients. In my spare time I enjoy sports, traveling, working in my yard and hanging with my kids.

Troy G. New, Jr., M.D.
Family has always been the most important thing in my life. As a physician, I strive to provide care to my patients in the same manner I would want someone to care for my own family. The practice of OB/GYN is unique in healthcare in that we are able to establish long-term doctor-patient relationships. Seeing patients back each year and hearing about their lives and family is one of the most fulfilling parts of my job. When I am not working I enjoy any outdoor activity, especially playing tennis with my kids, cycling, hiking, and working in my yard.

Kimberly S. Marshall, M.D.
All women deserve personalized and compassionate gynecological care through life's transitions. As an OBGYN, I have strived to be an advocate for my patients and help them maneuver through the often confusing and fragmented healthcare system of today. Whether you're struggling with finding the right birth control, with infertility, or with a high risk pregnancy - It is my heartfelt commitment to ensure you have the right information needed to make informed decisions about your health. I am blessed to be the proud mommy of two active boys, and in my free time I enjoy running, fishing and cheering on my local teams!
