TheKey in Encinitas's Cardiff-by-the-Sea district maintains a San Elijo Avenue office serving the Cardiff and greater North County senior community through its proprietary Balanced Care Method, a framework that structures caregiver routines around cognitive engagement, physical activity, nutrition, and social connection. Client Care Managers match caregivers to clients based on medical requirements, personality compatibility, and shared interests, a precision-matching system that supports the mobility-maintenance protocols prescribed by chiropractors at Leucadia Chiropractic Wellness Clinic. The national network spans 110-plus regions across 32 states, with the Cardiff location offering live-in caregiver placement and specialized Alzheimer's, Parkinson's, cancer, and stroke recovery programs staffed by experienced RNs and LPNs. Skilled nursing is available through the California operation, and neurocognitive assessments integrate with the brain-health monitoring at Braincare Performance Center – Cardiff. Highest-complexity engagements involve 24-hour live-in care for clients with advanced neurodegenerative conditions requiring multi-domain behavioral tracking and real-time family reporting through TheKey's digital care platform.
