Please note that members of the College of Registered Manual Osteopaths are covered by the Chamber of Commerce extended health plan that is managed by the Johnstone Group Inc. However registered manual osteopaths MUST mention that they have a DOMP or DO in each paid receipt they issue to Chamber of Commerce policy holders. This is required by the Johnston Group! Your treatment will not get reimbursed if you do not mention your DOMP or DO title clearly in the paid in full receipt.
