The Management Team
Living Well's management team members have held top leadership positions in major senior and health-focused businesses. The team has solid skills in health care programming, creating innovative solutions to eldercare, and executing complex business operations. Our founders are two compassionate gero-psychologists who are experts in working with adults with memory loss, movement disorders and other chronic conditions associated with the aging and disorders of the central nervous system. Steeped with decades of experience in two different models of elder and assisted care, throughout the course of their careers Doris and Tessa saw gaps in these approaches while noticing the benefits to adults receiving care at home, inspiring them to create Living Well.
