Chiropractic Center in York, PA

About Us

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.”

Wendy has been in management/ownership of the Chiropractic Center since she was in her 30s. She has been the TEAM Leader at HCO since 2008.  She also does the bookkeeping, billing, front desk, therapy, consultations with new light clients, and chiropractic patients reviewing their insurance verifications and treatment plans.  She does whatever is needed to ensure excellent patient/client service.  She allows her TEAM to manage their time providing manuals, training tools, and hands-on education to ensure their success!  Over the years, she has been blessed to witness personal growth in her TEAM and, even though some of them moved on to pursue other dreams, careers and aspirations. She experiences heartfelt happiness to have a part in this process.  She manages with love and concern for their well-being at all times.  While expecting professional standards and excellent client/patient care from her TEAM, she realizes they have personal needs and, at times, need compassion and understanding as they navigate through their challenge.  

She feels extremely blessed with her current TEAM in these ever-changing and uncertain times.  Bella, Diana and Nicki came to the office post-COVID.  HCO added several services which created constant changes and they did whatever it takes to assist in the processes.  She feels they are phenomenal!  She is excited about their present situation and looks forward to a bright, successful future!

With the addition of the Red and Near Infrared light therapy, she was able to bring her daughter, Nicole, on board and pioneer this service at their Chiropractic Center in York, PA. She loves working side-by-side with her. Nicole has been integral in the process, and Wendy looks forward to what the future holds for them.

She is married to Dr. Gary Harcourt.  She is the mother of three beautiful ladies. Nicole, Jacqueline and Monica.  Together, she and Dr. Gary have 6 children and eight (8) grandchildren. She is a golden retriever Mom, and she does not take that role lightly.  Romeo and Rocky live a very loved life.  They are always happy to see her no matter the length of time she is away, even if it is only 10 minutes.  She enjoys playing ball with them as that is one of their favorite things.  She loves spending her off-duty time with family, exercising, reading, cooking and getting her hands dirty in the gardens as she appreciates the beauty of nature and being outdoors.  She also enjoys decorating and creating welcoming atmospheres at the office and in their home.

Chiropractic Assistant

Bella has been with our chiropractic center in York, PA for over a year now as a Chiropractic Assistant. Her favorite aspect about it is the smiles on patients’ faces when they leave pain free and are reaching their health goals. Her job is important to her because she’s helping her community and forming strong bonds with her co-workers. She’s excited about all the new treatments we now offer, such as our Softwave therapy, and for what the future hold for the office.

In her free time, Bella enjoys traveling to our nations national and state parks, hiking in the mountains, and cooking with her boyfriend. She has two of the best feline friends, an orange tabby named Oliver and a black and white tuxedo named Walter.


Chiropractic Assistant

Diana has been with the team as a chiropractic assistant since November 2020. She values our patients and their kindness. She recently moved to York from Maryland, but she grew up in a Mexican household where her family only spoke Spanish to her which provided her with bilingual skills. This has enabled our office to communicate with many of our Spanish speaking patients. She is very grateful to have the opportunity to help the community and is excited for the new year. We are glad to have her working at our chiropractic center.

Outside of work, Diana enjoys spending the weekend with her friends and family. and of course, her son Mosley, who is a mini–Australian Shepperd. Her mother is a Mexican cuisine expert and desires to pass this on to Diana one day (fingers crossed). She loves the outdoors including roller coasters, ziplining and snowtubing. Her favorite pastime is going to concerts with her husband.


Chiropractic Assistant

Shelly first joined our team as a Chiropractic Assistant in November 2014. She remained a CA as she took on the accounts receivable position in 2016. Since then, she earned her bachelor’s degree in psychology at York College while continuing to work here at the office. She temporarily moved to Delaware to work in a research position in 2020, and now she is back with us as she completes her master’s degree at Towson University. She works hard behind the scenes to ensure all billing needs are met and is passionate about contributing to a positive environment where patients can (and do!) reach their biggest health goals.

Outside of the office, Shelly is an avid bookworm. She spends a great amount of her free time curled up reading mysteries, thrillers, & memoirs. There is most likely a cat in her lap while she’s doing this because her two boys, Oscar & Peanut, rarely leave her side. She also enjoys going to concerts and spending time in nature with her family and the love of her life, Jeremiah.
