Our team at TMJ Therapy is made up of kind, loving, caring people who have had first-hand experiences with TMJ disorders. Some of our staff members have suffered personally from the condition, and the others have worked closely with those who have. We understand the experience associated with the TMJ disorder, and we are here to help you in any way we can.
