Occupational therapist Clarissa Cowan, OTRL, specializes in neurorehabilitation at Kaiser Permanente Zion Medical Center in Allied Gardens, San Diego, practicing from the rehabilitation department at 4647 Zion Ave in the 92120 ZIP. Her OTRL credential designates her as an occupational therapist who is both nationally certified through the NBCOT and holds an active California OT registration, and her neurorehabilitation focus concentrates on stroke recovery, traumatic brain injury adaptation, and neurological condition management. Neurorehabilitation OT at Kaiser Zion operates alongside the facility's CARF-accredited inpatient rehabilitation unit, and Cowan's caseload intersects with physical therapy providers such as Louis Rosen, DO within the Kaiser physical therapy network on the same campus. The occupational therapy scope at this level covers upper-extremity retraining, cognitive rehabilitation, ADL adaptation for self-care tasks, splinting and orthotics fabrication, and home-safety evaluation for patients transitioning from inpatient to outpatient status. Allied Gardens' position between the I-8 freeway and Waring Road means the Zion campus serves a residential catchment that includes older housing stock with stairs, narrow doorways, and bathroom configurations that frequently require OT-driven modification recommendations for post-stroke patients. Behavioral and cognitive dimensions of neurological recovery sometimes involve parallel care with counseling providers, and community-based practitioners such as Michael Nelson in the College Area mental health network address the psychological adjustment component. Kaiser's integrated electronic health record gives Cowan's rehabilitation notes direct visibility to the referring neurologist, the primary care physician, and the discharge planning team within a single shared system.
