Kristy Williams, Project Management Specialist

Kristy Williams, Project Management Specialist

Kristy has lived in Mammoth since 1992, when she moved from Southern California “just for the season.”  She fell in love with the Eastern Sierra and eventually made Mammoth Lakes her permanent home – raising her family here.  Kristy graduated from the University of the Pacific with a BS in Business Administration, and since that time has fine-tuned her skills as an event and project manager.  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.

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.

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 self-published his first novel, a high-fantasy epic entitled "The Gräzland Tales", largely inspired by the grandeur and beauty of the Eastern Sierra.
