Dr. Comrie’s clinical experience includes work at a number of outpatient physical therapy clinics as well as at Good Samaritan Hospital in Los Angeles, Kaiser Permanente Woodland Hills and Arcadia Methodist Hospital.

Currently serving as a Clinical Instructor at Cal State Northridge, Dr. Comrie has been a teaching assistant at Mount Saint Mary’s College of Physical Therapy as well as Clinical Instructor at Azusa Pacific University. He volunteers with the Los Angeles Christian Health Centers, which works to provide free-of-charge services to the underserved in the area.
