Meet Our Doctors
Gary R. Mruz, D.C.
As a graduate of Sherman College of Chiropractic, I’ve been a dedicated healthcare professional in Upper Township since 1989. For over three decades, I've been committed to providing compassionate and effective chiropractic care to the community I proudly call home.
My practice is built on a passion for promoting overall wellness. I combine my expertise in traditional Chiropractic Care with Corrective Exercises, Custom-Fitted Foot Orthotics, and Nutritional Supplements and Counseling. I'm especially experienced in caring for some of our most vulnerable patients, with a focus on pediatrics and prenatal treatment, and shoulder and knee stabilization.
My goal is to help patients of all ages live healthier, more comfortable lives.
I offer a comprehensive approach to treatment, utilizing a variety of hands-on techniques to meet the unique needs of each patient. To stay current with the latest research and treatment protocols, I regularly attend post-education training.
I am especially proud of my long-standing experience in helping patients with challenging health issues. Throughout my career, many patients have come to me after seeking help from other providers with little success, often being told they simply have to live with their problems. My approach is to examine each patient for mechanical and structural issues that are frequently overlooked. When spinal function is impaired by injury or stress, optimal healing is impossible. By restoring balance to the mechanics of the body and spine, I can help enable my patients to heal and live a more active, healthier lifestyle.
My favorite moments away from the office are spent with my family. I love traveling with Donna, my wonderful wife of 40 years, and making memories with our three grown children, Joseph, Andrew, and Jessica, and our son-in-law, Zach. We're all big fans of the outdoors, and you can often find me kayaking, biking, or simply relaxing on the beach.
At South Shore Chiropractic, we listen, we care, and our whole staff has a desire to help.
