Dr. Carter W. Campbell
BSc., DC

Dr. Campbell earned early acceptance into the Doctor of Chiropractic program at the University of Western States while enrolled in a Bachelor of Kinesiology program at the University of Alberta. He completed his clinical residency at the Radix Pain & Rehabilitation Centre under the supervision of Dr. Farrell and is accepting new patients and happy to serve Dr. Farrell's patients if and when needed.

With a background in human movement and a degree in human biology, you will see Dr. Campbell putting his skills to work on patients in the full training facilities available at the Radix Pain & Rehabilitation Centre. Dr. Campbell is a passionate people person and equally invested in helping patients accomplish their personal health goals. Having undergone a personal health transformation himself some years ago, Dr. Campbell understands firsthand how difficult getting started can be and how frustrating injuries can be when they get in the way of training progress.


The Radix gym facilities allow patients to work with their doctor and literally demonstrate when and where their pain presents in their training routine. It also allows patients keen to get into the gym to ensure their form is mechanically sound to prevent injury. Highly trained in human movement and the diagnosis and management of musculoskeletal conditions, Dr. Campbell looks forward to helping you reach your health and fitness goals. 


Throughout his education, Dr. Campbell has visited various countries and hopes to have completed 50 countries before turning 50. Dr. Campbell now balances any of his (alleged) spare time between the art of cooking, exercising, golfing, and various winter sports.
