Marc Croker has been a chiropractor since 1999. He has been the principal chiropractor of Parramatta Chiropractic & Health Centre since January 2003. His treatment style utilises standard chiropractic manipulative therapy along with massage and stretching techniques to improve mobility and flexibility of joints and soft tissues to reduce joint and muscle tension. He works on the premise that increased soft tissue tension increases the likelihood of sprain/strain injuries and that an increase in flexibility may reduce pain and stiffness and the likelihood of recurrence. Marc believes that the success of chiropractic is based on encouraging increased patient fitness and flexibility.
