Holding a Doctor of Physical Therapy degree from the University of St. Augustine for Health Sciences, Erwin Caalaman practices in La Mesa at the Rehab United Sports Medicine & Physical Therapy clinic on Fletcher Parkway near Sharp Grossmont Hospital. Post-surgical rehabilitation protocols originating from the fellowship-trained orthopedic surgeons at Grossmont Orthopaedic Medical Group constitute a core referral stream, with Caalaman designing progressive loading programs for total knee and total hip arthroplasty patients within the first 72 hours post-discharge. California's direct-access law permits evaluation and treatment for the first 45 calendar days without a physician referral, a pathway that routes acute soft-tissue injuries directly from the field to the clinic. Caalaman's background in competitive fitness—including ownership of a CrossFit affiliate—informs his return-to-sport programming for athletes transitioning from rehabilitation to performance training at facilities like CrossFit La Mesa on University Avenue. Treatment protocols utilize instrument-assisted soft tissue mobilization (IASTM) with Graston-technique stainless-steel tools to break down fascial adhesions in post-operative scar tissue along surgical incision planes.
