Grossmont Gardens Senior Living operates a 425-bed campus at 5480 Marengo Avenue in La Mesa under RCFE License 374602548 and HCAI ID 206374041, combining independent living, assisted living, and skilled nursing under one Sinceri Senior Living management structure. On-campus skilled nursing holds a separate Long Term Care Facility license, enabling cardiac-event recovery and post-surgical rehabilitation with specialist follow-up coordinated through Cardiovascular Institute of San Diego for residents requiring ongoing electrophysiology monitoring. The multi-tier model allows residents to transition from independent apartments to assisted care to skilled nursing without relocating off campus, preserving social connections and care-team continuity. Resident dental care for the assisted living and skilled nursing populations routes to Gentle Dental Grossmont for prosthetic, restorative, and preventive oral health services adapted to geriatric patients. The sister community Grossmont Gardens Memory Care on Mills Street absorbs dementia-progression transitions when cognitive decline exceeds assisted living thresholds. Highest-acuity services include ventilator-weaning protocols and IV-antibiotic administration within the skilled nursing wing's acute-care-capable licensed beds.
