Chiropractic Center in York, PA

About Us

Harcourt Chiropractic offers a legacy of care

Our Chiropractic Center In York, PA has been providing chiropractic care for three generations. Our grandfather, J. Alfred Harcourt, D.C. was one of the most prominent pioneering chiropractors in the state of Indiana in the 1920′s, 30′s & 40′s. He graduated from the National College of Chiropractic in 1923 and his practice was located in Hagerstown, Indiana.

Our father, Robert J. Harcourt, D.C. also pursued a career as a Doctor of Chiropractic and practiced in Hanover PA, after graduating from National College of Chiropractic in 1952. He moved his practice to York in 1956 where he established and maintained a successful chiropractic center for over 30 years.

Three of his four sons chose to follow in his footsteps and earned their degrees as Doctors of Chiropractic. At this time Gary E. Harcourt, D.C. practices in West York serving York County residents with state-of-the-art natural health care.

Chiropractic is not medical care. It is a system of health care that heals without the use of drugs or surgery. Chiropractic health care helps retrain your body to take care of itself. If your bodily structure is not straight and true, you may feel pain, become ill or tire more easily.

People all over the world have found chiropractic centers extremely successful with pain management and relief. What is less known is that chiropractic care can also help your nervous and immune systems. Chiropractic health care focuses on your spine and body structure. Since this structure is the foundation of your body, it profoundly affects your whole health. A balanced, aligned body allows the natural healing systems you were born with to function normally, giving you back the health and vitality you have lost.

Health is the natural state of your body.

Put Three Generations Of Pain Relief Behind You!

“The practice of the future will give no medicine, but will interest his patients in the care of the human frame, in diet, and in the cause and prevention of disease.”
