Maxximus Murray

Office Manager

My name is Maxx Murray. I joined the Institute at the beginning of August 2026 as the Office Manager / Clinic & Events Coordinator. If you make it out to visit us in Colorado, you’ll see me at the front desk when you come in. I’m a native of the Washington D.C. area and am excited to be closer to the mountains – my younger siblings and I snowboard together, and the East Coast doesn’t cut it anymore! I’m looking forward to contributing to the Rolf Institute and community, as well as connecting with you, our members.
