She moved to Mammoth in 1971 and worked at Mammoth Mountain for 29 years, mostly in the Sports School and running the Children’s Sports School. She is certified by the Professional Ski Instructors of America; Alpine Level III, Adaptive Level II and Snowboard Level II. Kathy was also an examiner for Alpine Certification.

In 2001, Kathy “retired” from the mountain and pursued other interests. Her main ‘other interest’ was launching Disabled Sports Eastern Sierra! This is her passion and with all her dedication and energy, this program is a winner.

Finance Director

Laurel Martin moved to Mammoth in 2006 and has been loving it ever since. Being a beach girl at heart rather than a snow bunny, she has helped to develop and expand our summer offerings and helped to create a year-round adaptive program. But she has also discovered a love for winter sports … skiing, dog-sledding, skijoring and camping. After growing up in suburban Connecticut, Laurel headed west to attend college at the University of California-Berkeley. After graduating with a degree in Environmental Sciences with an emphasis on Biological Sciences, she headed back east to spend some time with her family and boyfriend. Following some pretty extensive travel and temporary employment opportunities, she found her dream job. Working at Connecticut’s Beardsley Zoo as a Zoo Educator gave her the opportunity to educate and excite children about nature and the environment. Unfortunately her dream job did not include big mountains, something her other half quickly became addicted to, once he knew they were out there. So the time came for Laurel to pack her things and head west again. This time she landed in Mammoth where she happily divides her time between exploring, climbing, hiking, and spending time with her 40 best friends, the Mammoth Dog Teams sled dogs. Volunteering with Mammoth Dog Teams has allowed Laurel to still get to work with animals and see the difference they can make in peoples’ lives. Laurel is happy to be a part of the Disabled Sports Eastern Sierra team and excited to see what the future holds as this great organization grows.

Emily spent four years working at a children’s science museum in Southern California. “It really brought a love and need to teach children, but not in a classroom environment,” she said. “I have to be actively doing something and moving around, it is impossible for me to sit still for more than 20 minutes.” Emily loves the cold weather and said that being on a mountain is her paradise. Emily is a skier, but also recently started learning how to snowboard.
