A $1 million donation from Bellevue, WA-based Aegis Living will help Seattle-based not-for-profit housing agency Plymouth Housing develop new permanent housing and enhance community support and services for adults experiencing chronic homelessness.

Aegis Living on Tuesday said the donation is the largest in its history.

Along with the monetary contribution, Aegis Living will help enhance training and support for Plymouth Housing residents, caregivers and volunteer staff members. The company will host regular workshops covering topics such as health and safety best practices for an aging population and caring for those living with mental and/or physical challenges. The senior living operator also will work with Plymouth Housing to develop activities for residents to create a sense of community and belonging. Many Plymouth Housing residents are older adults or veterans who may have dementia, disabilities, mental health challenges or substance-use conditions.

“The first step to a happy, healthy life is achieving the stability and security of long-term housing and care, but our work can’t stop there,” Aegis Living founder and CEO said Dwayne Clark said in a statement. “We must give people the opportunity to come alive and thrive through a sense of community and empowerment. We have done this at Aegis Living and hope to do the same for those at Plymouth Housing.”
