About The Doctor

Dustan J. Mattingly, D.C.

He graduated from Palmer College of Chiropractic in Davenport, Iowa in 1993. Upon graduation he setup his first practice in Chillicothe, Illinois which is close to his home town so he could improve the health of his family, friends and the residents of the town he grew up in.
