Andrew Mulford, GIS Manager

Andrew Mulford, GIS Manager

Andrew grew up in the countryside of Virginia where he spent his childhood rambling around in a hundred acre forest and kayaking about on the Western Branch Reservoir. With his wonderful mother Jan as a teacher and guide he learned to love the outdoors. Andrew studied Geography at Virginia Polytechnic Institute and used his newfound skills to navigate his way to the opposite side of the continent. He is happy as a clam here on the east side and really enjoys contributing to our recreational landscape through his employment with MLTPA. Andrew’s official title is GIS manager, but he sneaks out of the office on occasion to groom the Nordic trails at Shady Rest (snow permitting) and design and build multi-use singletrack trails.

She has managed events ranging from major, nationally televised events to smaller, local events and everything in between. Kristy has managed projects for MLTPA off and on since 2007. She has now re-joined the MLTPA team on a part-time basis and is excited to work with this talented crew.

Trevor Van Winkle, Photo & Digital Asset Manager

Trevor Van Winkle, Photo & Digital Asset Manager

Trevor moved to Mammoth after graduating from Biola University with a degree in Film Production & Editing. Falling in love with the area while visiting family and exploring the backcountry, he chose to remain in town rather than return to Los Angeles – a decision he's yet to regret. First coming into contact with MLTPA staff through the Mammoth Lakes Film Festival, he has since worked as a field photographer, photo librarian, and digital assets manager. He also works as a freelance photographer/videographer, post-production media specialist, and as a stage manager and lighting technician for Mammoth Lakes Repertory Theatre. In his free time, he can often be found running the MLTS (particularly the Town Loop), and has just self-published his first novel, a high-fantasy epic entitled "The Gräzland Tales", largely inspired by the grandeur and beauty of the Eastern Sierra.

Matt Angioli, Field Data Technician

Matt Angioli, Field Data Technician

Matt grew up in a southern California beach town, but always knew the mountains were home. As soon as he finished high school he moved to Mammoth and attended Cerro Coso Community College. After finishing community college he moved to Salt Lake City where he received a Bachelor of Science in Geography and a Bachelor of Science in Environmental Studies from the University of Utah. After finishing school in Utah, his first priority was to move back to the eastside of the Sierra. He loves living in Mammoth and spends his free time rock climbing and mountaineering. Matt works for MLTPA as a Data Technician and is psyched to be a part of such an awesome local organization.
