Facility Manager
Nathan P. Griffin
Nathan first came to Dyer in 2009 as a remodeling subcontractor and fell in love with the place at first sight. He soon found a role at the observatory that utilized his multitudinous building and problem-solving skills as well as guest relations experience honed during his decade at Breckenridge Ski Resort in Colorado. Nathan is charged with maintaining Dyer’s magnificent grounds and buildings in addition to facilitating our public and private events.
With a lifelong passion for music, Nathan spends his free time composing, playing, and singing for enthusiastic crowds around the region. The success of Dyer’s Bluebird on the Mountain concert series is due in large part to his musical and technical expertise.
