A Multi-disciplinary Team

Since 2002, Accountable Aging has provided professional care management services to address the unique needs of older adults and those living with disabilities. Our interdisciplinary team relies on experienced professionals from diverse backgrounds including gerontology, social work, nursing, mental health, home care, facility administration, home health, hospice, and government benefits programs. Although we work as a team, we provide a single point of contact for each client, their family, and service providers.

At Accountable Aging, our vision is to positively influence the way our community ages. In order to provide our clients with a one-stop-solution for private care as they age, we work closely with our sister company Family Tree In-Home Care to provide professional caregiving and private nursing services.
