Dr. Kortnie Strother

Dr. Kortnie Strother was inspired to become a dentist through the example set by her grandfather, the first dentist in a small town south of Houston, Texas. She strives to bring the same warmth and commitment to patient care and comfort that he once did.

Dr. Strother is a Diplomate of the American Board of Endodontics (the highest level of achievement for an endodontist) who is proud to return to the DMV where she once started her family. After graduating college at the University of Texas at Austin, Dr. Strother served as a Captain in the U.S. Army at Walter Reed Army Medical Center in Washington, DC and Fort Belvoir Community Hospital in Virginia where she was a dietitian serving wounded warriors and their families. During this time, she received a Master of Science degree in Dietetics from Baylor University. Dr. Strother left the Army to pursue dental school at the University of Texas Health Science Center at Houston where she also earned a certificate in Endodontics and a Master of Science in Dentistry (MSD) degree. She spent nearly a decade practicing endodontics in Austin before returning to the nation’s capital to found Rock Creek Endodontics.

Dr. Strother is a breast cancer survivor and enjoys gardening, volunteering, traveling, and spending time outdoors with her husband and two children.
