Lisa Holan, Secretary

Lisa Holan grew up in Toronto, Canada, and moved to Truckee in 2000 after completing her Master’s degree in Ecology. Following graduate school, Lisa traveled around Asia for several months then settled in tiny Bear Valley, CA, working as a climbing instructor for the summer. Her (now) husband Jan (“Yan”) was determined to keep her here by instilling a love of the Sierra, and they climbed, skied, hiked, biked, swam and camped all over the Tahoe basin and east side of the Sierra. It worked: after teaching several semesters at Sierra Nevada College, Lisa now works as an aquatic ecologist at UNR, and is currently introducing their 9-year-old son to all the activities and places she loves in the Sierra. Her favorite place of all is a stretch of the Truckee River, a few minutes walk from the back of their house, that Lisa has visited almost daily in all seasons for the last decade with her husband, and dog and now her son.
She is pleased to join MAP and have a concrete way to help protect the cherished natural places in our community and promote smart development.
