Our Clinic

Drs. Ryan and Allyson Kathalynas formed their business, Kathalynas Spine, Sport, and Rehabilitation, in 2010 after graduating with a Doctorate of Chiropractic degree from Logan University in Chesterfield, MO. The husband and wife team established and grew their practice for the next ten years in Dr. Ryan’s hometown of West Frankfort, IL. During this time, the doctors treated patients in three separate locations trying to fulfill the demands of their growing practice. With their patients’ best interests in mind, the doctors were prompted to build their dream practice. Construction of the new facility began at the end of 2019 and was completed at the beginning of 2020. Drs. Ryan and Allyson Kathalynas now proudly serve their patients at their new location, which is just six miles away in Dr. Allyson’s hometown of Benton, IL.
