Phil has worked as an Interpretive Specialist for California State Parks, Development Manager with the Nevada Conservation Corps, and non-profit outdoor education centers.

Portrait of Mike
Mike Barbee (Gray Wolf)
Born in Coloma, Mike grew up in the small Michigan town exploring the surrounding woods and participating in “anything outdoors”. Mike’s curiosity of the natural world led him to study Education while minoring in Science and Mathematics at Western Michigan University. Mike has lived in almost every region of the United States coaching collegiate Cross Country and Track & Field, however the “Range of Light” or Sierra Nevada Mountain range drew him back to California’s Central Valley and the University of California, Merced. Mike views outdoor education as a “best of both worlds” when it comes to combining his love for the outdoors and scientific discovery.
