Terwilliger Plaza offers Assisted Living, Independent Living, and Memory Care, allowing residents to select the level of day-to-day support that best meets their health status and lifestyle preferences. The Assisted Living program provides help with activities of daily living, Independent Living residents maintain autonomy while still having access to on-site resources, and Memory Care is structured to meet the needs of individuals with cognitive impairment through secured environments and specialized staffing.

Residents have access to medical support that includes routine Diabetes Care, scheduled visits with an on-staff or visiting doctor, and therapy sessions with a Speech Therapist. Additional on-site clinical services cover Incontinence Care, Ambulatory Care for mobility challenges, and rehabilitation therapies delivered by Occupational and Physical Therapists. A Podiatrist is also available to address foot health, reducing the need for external appointments and supporting residents who may have complex care plans.

Accommodations include private or semiprivate apartments with access to maintained outdoor areas that encourage safe fresh-air activities; parking is available for residents and visiting family members. Not all rooms or units have every feature, so prospective residents should verify specific layouts and options during a tour.

The dining program provides three daily meals prepared by the culinary staff, with attention to dietary requirements and physician-ordered restrictions. Menus rotate regularly to support balanced nutrition, and meals are served in a communal setting that encourages social interaction.

An activity center hosts daily programs ranging from exercise sessions to hobby groups, and scheduled social outings allow residents to engage with the greater Portland community. These services aim to support physical health and social engagement without requiring residents to arrange transportation or logistics on their own.
