“I’ve been around chiropractic medicine my whole life. My father started Cavallo Chiropractic Clinic in 1949 and I always knew I wanted to follow in his footsteps. My sister, brother, cousins and uncles are all chiropractors as well, so it’s a big part of my story. After all these years, I’m still so passionate about helping patients heal naturally and get in the best shape of their lives.”

--Dr. John Cavallo


For 25 years, Dr. John Cavallo has been diagnosing and treating patients with common chiropractic issues. He is the only Board Certified Diplomate of Rehabilitation in Lancaster County, and one of only 35 in the state of Pennsylvania.

Dr. Cavallo earned his DC and DACRB from Cleveland Chiropractic College, Kansas City, Missouri in 1994. Born into a family of chiropractors, Dr. Cavallo's uncle, John DeMatte, became the first chiropractor to join the staff of a medical hospital in Pennsylvania.

With that, Gnaden Huetten Hospital in Lehighton PA, became the first non-osteopathic hospital in Pennsylvania to admit chiropractors to its medical staff. Continuing that kind of revolutionary progress is what drives Dr. Cavallo to offer the highest level of care to his patients.

Dr. Cavallo lives in Lancaster County with his wife Ashley and their two young children. When he’s not helping patients, Dr. Cavallo loves archeology and megalithic architecture. He enjoys studying the fascinating history, cultures, and music of the world.


Dr. Joshua Rittenhouse, DC

“I was first introduced to chiropractic care as a child after suffering a sports injury while playing soccer. The treatment I received delivered amazing relief and I was once again able to play the sport I loved so much. It was an incredible feeling! I was so grateful and never took my health or my body for granted again. I continued receiving regular adjustments to keep myself healthy. The impact on my overall well-being was undeniable. That’s when I discovered a real passion for helping others through chiropractic care. I can’t wait to meet you!”

--Dr. Joshua Rittenhouse 

Dr. Rittenhouse utilizes a diverse set of chiropractic techniques, including RockTape Fascial Movement Taping and NIMMO Trigger Point Therapy, to help relieve pain and restore movement. He graduated Summa Cum Laude from New York Chiropractic College. While at NYCC, he was inducted into the Phi Chi Omega Honor Society, participated in intramural sports, and was a member of multiple clubs.

Prior to chiropractic school, Dr. Rittenhouse attended Messiah College in Mechanicsburg, PA, where he earned his Bachelor’s Degree in Biology. He was born and raised just outside of Philadelphia, PA, and currently lives in Ephrata, PA with his wife, Amy.

DR. Steven Zellers, DC

“I’ve always been passionate about helping others. I worked in Cardiac Rehab outside of Atlantic City, New Jersey for over six years before attending NYCC. I wanted to find a way to continue working in healthcare and be able to affect more lives in a positive way. I remember being inspired by a story I saw on T.V. about the impact of chiropractic on athletes. Not long after, I shadowed a chiropractic doctor for a day, and decided that’s what I wanted to do with my life.”

-- Dr. Steven Zellers, DC



Dr. Zellers earned his B.S. in Exercise and Sport Science from Penn State University in 1996 before graduating from New York Chiropractic College in 2007. He has been practicing for over 11 years. Although his primary focus has been diversified adjusting, his range of modalities include drop technique, instrument-assisted adjustment, myofascial release, trigger point therapy, and soft tissue manipulation. He also likes to incorporate low-tech rehab exercises and in-home stretching programs to facilitate patient recovery.

Alongside his wife, Mary, Steven enjoys hiking and biking with their two kids, Nathan and Alexandra, watching their sporting activities, and having family game and movie nights.
