Four Diamonds in West Covina is a residential care home that centers its services on residents with complex medical needs. The staff is prepared to manage wandering behaviors at any time of day, stay with residents who remain awake through the night, oversee wound care, supply and monitor oxygen, and follow physician-ordered special diets. Team members also supervise diabetics on oral medications and are trained to work with advanced dementia conditions.

The community maintains a 24-hour nurse on call, runs background checks on all employees, and schedules both awake and asleep night-shift coverage. Security measures include staff on site around the clock, a fenced rear area, door alarms, and resident pull cords that alert caregivers. On-site podiatry visits limit the need for outside appointments. Caregivers provide full assistance with bathing, eating, dressing, and toileting, and can support transfers ranging from simple standby help to two-person or bed-bound moves using walkers or wheelchairs as needed.

Private rooms are available, and many come furnished, offer cable service, and permit residents to paint or otherwise personalize the space; however, not every accommodation includes all of these features. Some rooms have private bathrooms, while others share facilities depending on availability and resident preference.

Meals follow a set menu that meets general nutritional guidelines, and snacks are offered between meals. The kitchen can modify selections to comply with physician-ordered diets, and caregivers are available to give full assistance with eating when required.

Residents have access to outdoor smoking areas, barrier-free pathways for wheelchair users, community-wide internet, and maintained communal gardens for relaxation or informal gatherings.
