A place for healing, stewardship, and connection.


Greystone Estate
Jefferson County, Colorado

Mycelia is proposing a small residential behavioral health treatment center at the historic Greystone Estate in Evergreen. The plan is centered on the adaptive reuse of Greystone's existing buildings and developed areas — creating a structured setting for extended-stay treatment while preserving and investing in the property for the long term.

Greystone has been part of the Upper Bear Creek landscape for more than a century. Mycelia sees an opportunity to give this remarkable property a purposeful next chapter — as an intentional place of healing built around a promising, highly integrated model of residential behavioral health treatment.

Mycelia brings together evidence-based clinical treatment, trauma-informed care, experiential therapies, sustained personal practice, integration, aftercare and continued community support within one extended residential experience. The idea is not simply to help people make progress while they are at Greystone, but to help them understand the underlying sources of their struggles, build practices that support lasting change, and carry that work back into their families, relationships and communities. 

Greystone is unusually well suited to that vision. Its existing residences, gathering spaces, privacy, natural setting and surrounding land allow treatment, reflection, community, recreation and connection with nature to happen together in one place. Rather than replace what is here, Mycelia proposes to steward it — reinvesting in Greystone's historic buildings, preserving its mountain character, caring for its land and forests, and keeping this extraordinary Estate intact and contributing to the Evergreen community for generations to come.
