Howdy! My name is James Townson and I am excited to be back and serving the Waco community. I was born and raised just outside of Waco in Whitney, Texas. After high school I attended what many believe to be the best university, Texas A&M, where I earned a Bachelor of Science in Biomedical Science in 2007. A year later, my wife and I ventured out west where I attended the California School of Podiatric Medicine in San Francisco. I received numerous honors, and graduated Cum Laude in 2012. Following medical school, I completed my three year residency program at the Raymond G. Murphy VA Medical Center in Albuquerque, New Mexico, where I was honored to serve those who served our country. My three years of extensive surgical training consisted of pediatrics, diabetic wound care, sports medicine, rear foot/ankle reconstructive surgery including arthroscopy, ligament and tendon repair, lower extremity fractures, total ankle replacement and Charcot reconstruction. Additionally, I was trained on Poseti Clubfoot casting to treat wee little ones born with clubfeet. I push myself to constantly learn new techniques so that I am able to take on any problem I am faced with.

I am blessed to be married to my beautiful wife, and have two 2 boys. Growing up on Lake Whitney I fished a lot and it is something I still enjoy to this day. I especially enjoy bay and deep sea fishing. I love the outdoors and enjoy many sports with my focus being on anything Texas A&M, especially football.

Specialty Areas

The Heart of Texas Heel Pain Center

Millions of Americans suffer from heel pain on a regular basis, for a wide range of reasons—shoes, occupations, hobbies, structural problems with their feet, and more. But heel pain is not inevitable. And at our Heart of Texas Heel Pain Center, the doctors of Waco Foot & Ankle can diagnose and reverse your heel pain using a variety of both traditional and advanced methods, including stem cell therapy and MLS laser therapy.

Sports Injury Care

Texans love to play—whether that means football, soccer, baseball, running, or any other sport! Unfortunately, that can often lead to painful, sometimes even debilitating injuries to the feet and ankles. Fortunately for you, the team at Waco Foot & Ankle offers advanced care options for traumatic injuries like sprains and broken bones, as well as overuse injuries like shin splints and stress fractures. The goal, of course? Getting you back in the game at 100%, as quickly and as safely as possible.

Women’s Foot Care

While almost all foot problems can occur in both sexes, some conditions are just much more likely to develop in women due to differences in foot structure, biochemistry, and even popular footwear styles. Our physicians are experts in dealing with common women’s foot problems—including bunions, hammertoes, and skin conditions—and can provide multiple treatment options to best suit your individual needs and lifestyle.

Wound Care

Did you know that about 25% of people with diabetes will develop a foot ulcer at some point in their lifetime—and that nearly 100,000 Americans per year require amputations to stop the progression of diabetic wounds with uncontrolled infections? At our office, we provide advanced wound care—including the use of amniotic stem cells—to heal diabetic ulcers, venous stasis ulcers, and other types of lower extremity wounds as quickly as possible.
