As a writer and actor originally from Chicago, Hayes began his career performing theater and comedy and has gone on to have a long and diversified career in film and television. Over the years, Hayes has worked closely with many charitable organizations, including Feeding America, Communities in Schools, and The Art of Elysium, a powerful organization that provides creative therapy for children facing end of life issues. He moved to Sun Valley in 2020 with his wife, Ali, and their two children Theodore and Vivienne.

He was initially drawn to Higher Ground because the organization provided an incredible experience for close family friends whose children experienced health difficulties, and his personal stance on supporting returning veterans. From family members to friends, he believes it’s our responsibility to care for those who served long after their time in the military is over.

He loves how Higher Ground helps participants confront struggles and transform them into skills to bring back into their daily life. He’s experienced the insight and energy that one can get from biking, skiing, rafting, and hiking and enjoys helping others overcome any obstacles to feel the same. The recreational therapy that Higher Ground provides stays with participants long after their visit is over.

For the past two years he has greatly enjoyed his time on Dollar Mountain with the Alpine Green Team. He’s excited to continue his volunteer work and explore new ways and opportunities for Higher Ground to grow and reach even more people.
