Whole Arts Auxiliary


Here at the Joshua Tree Retreat Center (JTRC), also known as The Institute of Mentalphysics (IOM), we meet many amazing people who resonate with this place and are interested in engaging with us. To connect with these allies, we have formed the Whole Arts Auxiliary. Launched earlier this year with an inaugural working board of design professionals who are volunteering their time and expertise, we now invite you to become a part of this exciting new group.

What drives the Whole Arts Auxiliary is the preservation and protection of the Joshua Tree Retreat Center with the active participation of community. Our Mission is to steward the Lloyd Wright Buildings and the spiritual philosophy of Organic Architecture that is affiliated with the IOM.

Whole Arts Auxiliary Membership is a way to get people like you involved in arts and social happenings that are unique to our desert community. These events and activities will raise much needed funds for the restoration and preservation of the architectural masterpieces, the rich natural environment and the restorative spiritual energy found at the Joshua Tree Retreat Center.

The Whole Arts Auxiliary’s philosophy is fun with a purpose. We hope that you will consider joining us!
