Dr. Swanson is the resident Doctor of Chiropractic for Holistic Veterinary House Calls.   Dr. Swanson treats both animals and people to keep the whole team feeling great.

Needless to say, but becoming a Chiropractic Physician was exactly where his life was headed.  Helping others achieve greater health and happiness has been Dr. Swanson's main focus.
