Dr. Amanda Nichols

Chiropractic Intern

She decided to become a chiropractor because she was inspired by her mother who is a massage therapist that worked in many chiropractic practices. Her mother took her to get adjusted when she was young and it helped relieve her back pain, which inspired her to pursue a career in the chiropractic profession. She loved the idea of healing people naturally with chiropractic. Prior to attending Palmer, she acquired her associate’s degree from Rock Valley College in 2012.
