Rosario Assisted Living’s history begins more than four decades ago when it first opened its doors as Anacortes Convalescent Center. Built in 1973, the facility at the time was a 119-bed Skilled Nursing Facility.

The original building received a complete retrofit in 2000, which downsized the facility to 44 beds, but with a brand new, adjacent 84-apartment Assisted Living complex. Upon completion of this construction, the campus was renamed Alliance Living Community.

Rosario Assisted Living is now operated by Hyatt Family Facilities, based out of Yakima, WA
