Our Story

Locally owned senior living, led by people who know your name

Arcadia Senior Living was built on a simple conviction: that growing care needs should never force someone to give up community, comfort, or dignity. That belief shapes everything we do.

Meet Tammy

Tammy Thwaite is Principal & CEO of Avant Senior Housing Managers and Consultants, LLC, the company that operates Arcadia. She has dedicated her career to senior housing since 1994, with hands-on experience across dining, life enrichment, the business office, sales and marketing, and executive leadership. Before founding Avant, she served as Co-President of LifeStyles Senior Housing Managers, overseeing 11 communities and more than 1,300 units across the full continuum of senior living. More than three decades in, Tammy is driven by a belief that senior living should feel like home, never institutional.

“Senior living should never feel institutional. Every resident deserves dignity, purpose, happiness, and the opportunity to continue living a meaningful life surrounded by people who genuinely care.”
– Tammy Thwaite, Principal & CEO, Avant Senior Housing Managers and Consultants, LLC

Why Tammy Built Arcadia

For Tammy, this work is personal. When her own father needed more care, she searched for a community that could meet his higher medical needs without stripping away the friendships, activities, and sense of belonging that kept him thriving. She could not find one that did both well. Rather than accept that gap, she set out to build it. That search became the blueprint for Arcadia: a community where growing care needs and a full, connected life are never an either-or, and where no one has to leave the people and place they love simply because their needs change.

Locally Owned, Personally Run

Because Arcadia is locally owned and operated rather than run by a distant national chain, decisions are made by people who know our residents by name. There is no corporate bureaucracy between a resident’s need and the person who can say yes. That closeness is what makes Arcadia feel less like a facility and more like family, and it lets us respond quickly and personally when it matters most. Hear what our residents and families say.

The Arcadia Difference

  • Locally owned and operated, with leadership personally involved
  • An average care ratio of one caregiver to seven residents, compared with a 1:12 industry standard
  • Care staffed by need, so residents can age in place rather than move as their needs change
  • Month-to-month leases, with no long-term contract and no buy-in fee
  • Two welcoming communities in Portland, Oregon and Washougal, Washington
