Meet The Team

Our goal is to treat as many patients as possible in their quest for health and wellness, and to educate them about chiropractic so that they may, in turn, educate others.

We’re committed to educating all our patients about the spine and its influence on the body’s overall health. Therefore, we provide information about our tools and services as well as other natural and non-invasive solutions to ailments. We also deliver free seminars regularly to help you and the general public make educated choices in restoring and maintaining your health and that of those you care about.

Dr. Karen Callaghan and Dr. Tony Holvick – met in chiropractic school. They got married after graduation and opened Atlantic County Family Spine and Rehabilitation in 1993. They’ve enjoyed watching patients they first treated as children grow. They're thrilled when they return from college to get adjusted and love when they start their own families and continue to come to us for care.

We pride ourselves on delivering the best care we can to help you live your best life. Our team of doctors and administrative professionals is committed to friendly, attentive service. If there’s anything we can do to help you please don’t hesitate to let us know.

Our office has grown due to the many patients who have recommended us to their friends, families, neighbors, and coworkers. We hope you’ll be just as satisfied with the care and treatment you receive and will also refer those you know and love to us.
