Aging with Grace Pediatric Care Prenatal SOT 1.1M+ Adjustments

Dr. John Murray founded Murray Chiropractic in June 1980 after graduating from Palmer College of Chiropractic — the oldest chiropractic school in the United States. He has lived in Clinton since 1965 and has practiced from the current home office at 10 Anderson Road since December 1986. In the 46 years since graduating, he has personally performed over 1.1 million adjustments and built one of the busiest chiropractic practices in New Jersey, serving generations of Hunterdon County families.

Dr. John continues to see patients daily and anchors the practice's Aging with Grace program — chiropractic care designed for seniors who want to maintain mobility, reduce pain, and stay active. At 70, Dr. John takes no medications and remains active in his practice and his community. His certification in the NAS (Nautilus Advanced Strength) manual super-slow training protocol directly informs how he works with senior patients on strength preservation, functional capacity, and longevity.

Dr. John has been adjusting children for 45 years, including patients under one year of age. He is also Sacro-Occipital Technique (SOT) certified, which informs the practice's prenatal care approach for expectant mothers dealing with sacroiliac joint issues common during pregnancy.

During his time at Palmer, Dr. John was a member of the college's national championship rugby team in 1978. The athletic background continues to inform his clinical approach to active patients of all ages.

Chiropractic, through personally being adjusted at 17, changed my life. It gave me a cadence — and an innate feeling that it was just right for me. I had no plans for college or chiropractic, but it moved me emotionally to provide a vital, service-based approach to health and chiropractic healing.

— In Dr. John's own words, on becoming a chiropractor

Healing takes time and it won't be easy, but it will be worth it. Lifestyle modification is required to optimize your results. You will learn how to help yourself through understanding and practical application. Patient participation is required.

10 years at Murray Chiropractic · Moravian University women's basketball, 2008–2012

Prenatal & Postpartum Pediatric Cox Technic Activator Thompson KST/ArthroStim Blair Upper Cervical SOT

Dr. Hilary Schweitzer is a graduate of Palmer College of Chiropractic and the daughter of Dr. John Murray. Chiropractic has been part of her life since the day she was born — her father gave her her first adjustment hours after delivery. She is proud to have followed in his footsteps and joined the family practice after completing her training at Palmer.

A North Hunterdon High School graduate, Dr. Hilary was a four-year starting point guard for Moravian University's women's basketball team (2008–2012), where she ranks 11th all-time in career assists and helped lead her team to the 2010 Landmark Conference championship. She has been inducted into the North Hunterdon Athletic Hall of Fame as an individual athlete for excelling in soccer (goalie), basketball (point guard), and softball (outfield, leadoff batter), and is also part of two inducted teams — the 2006 New Jersey State Championship softball team and the 2006 Group 4 sectional championship soccer team. She now serves as Vice President of the North Hunterdon Athletic Hall of Fame committee.

Dr. Hilary works with patients of every age and stage of life, from newborns to patients in their nineties and beyond. She has particular focus on prenatal and postpartum care, women's musculoskeletal health, and sports injury recovery. As a mother of two young children (ages 3 and 1.5), she received chiropractic care from Dr. John and Dr. Zak throughout both of her pregnancies and the postpartum period — an experience that grounds her clinical work with expectant and new mothers.

Dr. Zak joined Murray Chiropractic in 2018 after graduating from Palmer College of Chiropractic, and has been part of the practice for eight years — both professionally and personally, as son-in-law to Dr. John.

A dedicated husband and dad, Dr. Zak values family and an active, healthy lifestyle, and that shows up in how he cares for patients. His philosophy centers on getting to the root cause, supporting the body's natural ability to heal, and empowering patients with the tools they need to stay well long-term.

He is trained in a range of chiropractic techniques including SOT, Cox, Thompson, Gonstead, and Diversified, allowing him to tailor care to each patient's needs.
