Our Story
After a wildfire, the rosebay willow herb, commonly known as fireweed, is one of the first plants to rejuvenate the scorched landscape. This resilient flora enriches the devastated earth, paving the way for the forest’s revival. At Rosebay Behavioral Health, we emulate the fireweed’s role, fostering growth and renewal for our people by nurturing a foundation where healing can flourish.

A Dream Realized by Our Founders

With extensive experience in mental health care, they recognized a significant need for a dedicated, long-term, high-acuity mental health treatment facility in Northern California. Confident in their vision and expertise, the founders began assembling the ideal team. Their collaboration with Kristina Wandzilak marked a pivotal moment, further solidified by joining forces with Charlie Litchfield to complete the founding team.
