Our philosophy is to seek health and to assist each person in becoming their own healer. This is in line with osteopathic principles:

  • The body is a unit; the person is a unit of body, mind, and spirit.
  • The body is capable of self-regulation, self-healing, and health maintenance.
  • Structure and function are reciprocally interrelated.
  • Rational treatment is based upon an understanding of the basic principles of body unity, self-regulation, and the interrelationship of structure and function.
