Proper Healthcare operates a walk-in clinic at 5565 Grossmont Center Drive in La Mesa's Grossmont medical corridor, adjacent to Sharp Grossmont Hospital on the Grossmont Medical Center campus. The clinic's location within the multi-tenant medical complex places it alongside specialty and primary care practices, with on-campus laboratory and imaging services available through neighboring facilities like Grossmont Medical Plaza for diagnostic workups that exceed walk-in scope. Serving La Mesa, El Cajon, and surrounding East County communities, the practice treats non-emergency illness and minor injury on a walk-in basis from the same Grossmont Center Drive medical campus that houses orthopedic, ENT, and podiatric specialists. Post-visit follow-up for musculoskeletal complaints routes through the campus's physical therapy corridor, including Grossmont Orthopedic Physical Therapy in the adjacent building. The clinic's campus positioning provides direct access to Sharp Grossmont Hospital's emergency department for cases requiring escalation beyond walk-in-level acuity.
