Dr Hall

Kipp Hall, DC


I was raised in Newcomerstown Ohio which is a small town about an hour and a half east of Johnstown. I graduated from Ohio State with my degree in Engineering in 1980. My decision to become a chiropractor occurred while I was working as a Quality Assurance Engineer at a nuclear power plant in Illinois.

After attending a friend’s wedding, I began to experience severe low back pain. I was confused because I hadn’t done anything to hurt my back. A friend suggested I see a chiropractor. As they say, the rest is history. The chiropractor performed an evaluation, explained the problem and began treatment. The treatment was effective and I was soon back to normal. During my treatment, my chiropractor explained the relationship among the spine, the nervous system, and the healing power of the body. Not only was chiropractic effective for pain relief, it was also a natural system of healthcare that improves the function of the body. It made sense to me!

The short story is I left my job and was off to Palmer College of Chiropractic in Davenport, Iowa. I graduated cum laude from Palmer College in 1983. Over the next several years, I worked in practices in suburban Chicago and San Diego. Finally, we decided it was time to return to Ohio. I opened Johnstown Chiropractic in July of 1995 and have been happily treating residents of Johnstown, Alexandria, Croton, Granville, Utica, Sunbury, Galena, Westerville, Newark, Pataskala and the rest of northwest Licking and northeast Franklin counties since then.
