Dr. Ward Peterson opened the doors in 1985. In 2018 his son, Dr. Tim, took ownership — and today Ward's son, daughter, daughter-in-law, and Dr. McKenzie Slattery all serve under the same roof. When we say we treat your family like our own, we mean it literally.
Gentle, specific, Christ-centered care — every doctor here practices the no-twist, no-crack philosophy the family has been known for since 1985.
Owner · treating chiropractor
Tim grew up in his father's practice and graduated magna cum laude from Palmer College in 1995. He returned home to San Antonio in 2007 and took ownership of the family practice in 2018. Since 2001 he has built his care around the Torque Release Technique — gentle, specific, and tailored to each patient.
Founder · chiropractor (semi-retired)
Dr. Ward founded Peterson Chiropractic in 1985 after graduating from Palmer College and answering a clear calling to serve. Four decades on, the office still runs on the conviction he set down at the start: "This is God's office." He continues to care for long-time patients, many of whom now bring grandchildren.
Chiropractor · pregnancy & pediatric care
Dr. McKenzie graduated Cum Laude from Sherman College in 2024 and earned her Webster Technique certification in 2025. She brings fresh energy and a gentle touch to the practice, with a special heart for expectant moms, babies, and growing kids. Patients love her warmth and her thoroughness.
Most of the team shares the Peterson name — and the ones who don't are treated like they do. These are the faces you'll see at the desk and in the therapy room.
Chief Operating Officer
Dr. Tim's brother and Dr. Ward's son, Joshua keeps the office running and has been part of the practice since 2000.
Community Outreach & Education
Dr. Ward's daughter, Gretchen leads the practice's community education and outreach with the same heart for service her dad built it on.
Front Desk & Therapy Assistant
Married to Joshua, Ann is often the first friendly voice you'll hear and a steady hand in the therapy room.
Office Manager
Heather keeps schedules, insurance, and the day-to-day flowing so the doctors can focus on you.
Patient Care
A familiar, caring presence in the office since 2021 — Bianca helps make every visit feel personal.
