Chiropractor San Antonio TX Tim Peterson

Owner & Chiropractor

Dr. Tim Peterson D.C.

“Back in 5th grade I decide that I would be a doctor. I was good at science, fascinated by how the body functioned, and excited about helping people,” recalled Dr. Peterson. “At that time, my dad was a pharmacist and I had never heard of chiropractic. A couple years later, he packed us all up and moved from San Antonio to Davenport, Iowa to attend Palmer College of Chiropractic.

As I made my journey through high school, my dad would talk about patient success stories from his new office, and I had a few personal chiropractic experiences to celebrate as well. In my senior year of high school, I realized my passion for helping people would be best accomplished through chiropractic. After receiving a Bachelor's Degree from the University of Texas at Austin, I was headed on my journey to Davenport, Iowa and Palmer College of Chiropractic.”

“I was pleasantly surprised by the rigor of the coursework. I was inundated with courses in anatomy, physiology, and chemistry as well as all the courses that built on that solid foundation to produce in me a Doctor of Chiropractic who was well prepared to care for his patients.”

After Graduating

After graduating magna cum laude in 1995, Dr. Peterson worked in his practice, as well as, with several other chiropractors. In 2007 he had the opportunity to return home to San Antonio to work with his father. In 2018 he took over ownership of Peterson Chiropractic. This has allowed Dr. Ward to travel more and spend his time enjoying semi-retirement with his wife.

“It is a privilege getting to work with my family”, Dr. Peterson says, “and each patient who comes into our office is welcomed with open arms into our family. I believe we deliver the best and most gentle chiropractic care in town along with the best customer service. Even though most people come to us as a last resort, we love to see people before they get to the point of desperation. That’s why we are a family practice that focuses on teaching and helping families live healthy lives from birth through to old age.”

Aside From Peterson Chiropractic

Dr. Peterson is married to his lovely wife Christy, a nurse practitioner, and has 3 adult daughters, 3 stepsons, and 1 grandson. He is passionate about spending time with family, traveling, and fitness.

Chiropractor San Antonio TX Ward Peterson

our Founder & Chiropractor

Ward Peterson D.C.

“I had been a Registered Pharmacist for 7 years and, each year, was becoming more discouraged about what I saw”, admits Dr. Ward Peterson. I began reading about how chiropractic looked at health and found that chiropractic put in words what I always thought that health is. I got excited because I found that just covering up symptoms, which is what I had seen from medicine for years, was not the only type of health care.

So, a year and a half later I found myself moving my wife and 3 children from San Antonio, Texas to Davenport, Iowa to attend Palmer College of Chiropractic.

When I got to Palmer, I was not sure if I hoped that it would be easy or that it would be hard as I already had had 5 years of pharmacy school and was married through most of those years. Well, I am glad that it was hard. The major emphasis was on anatomy and human physiology, X-rays, diagnosis, chiropractic adjusting techniques, and patient care in the Palmer College Public Clinic. Yes, the courses were hard, but I learned so much more than I thought was possible for me to learn. I also gained a great deal of confidence that I could be able to help people.

After Graduating

After graduating in 1985, Dr. Ward returned to San Antonio to establish Peterson Chiropractic.

“We love helping people,” smiles Dr. Ward. “We know that many people are apprehensive when they go to a chiropractor for the first time. We understand that many people don’t know what we do, so we make a point to explain everything in advance, answer questions and even give a short tour of our office. You see our goal is not only to get you feeling better, but we want you to live better for the rest of your life. To do that we need to teach you how, so we give classes and are constantly working with you individually. In our office, we use a very gentle method (no bone cracking) called Torque Release. Chiropractic research has gone towards a lower force but very specific adjustment.

Away from Peterson Chiropractic

Dr. Ward has begun to spend much of his semi-retired time down in the Valley with his wife Pat. They have 3 grown children, 3 grandchildren and 1 great-grandson. He loves to exercise, do projects, and walk on a regular daily basis.
