CEO

Heidi Anderson

Heidi brings 30 years of experience in non-profits to TTC – ranging from education, arts and for the past 8 years protecting green space and building additional trails for Central Texans. She and her family regularly enjoy the Trail for its urban access to nature and connectivity to the community. Heidi’s commitment to the Trail lies in the belief that this treasured asset, within Austin’s core, is at the heart of what makes our city great and our people healthy.

Chief Operating Officer

Hanna Cofer

Hanna brings 20 years of experience in nonprofits ranging from local conservation to international social enterprises, giving her a strong history of driving program expansion and sustainable growth. She has a strong passion for the Austin community and believes that nothing embodies Austin like the Butler Trail which she grew up alongside. When not on the Trail or working with TTC, she volunteers with various animal welfare and musician support organizations and can be found in the Hill Country with her dogs or at a local concert.

Executive Projects Director

Charlotte Tonsor

Charlotte is a native Texan with over 19 years of experience in landscape architecture and project management in Austin and across Texas. She has led and designed projects ranging from parks to corporate campuses and sports venues to children’s gardens. A country girl at heart, she is passionate about outdoor spaces in the city for everyone to use and enjoy. She believes that The Trail and Lady Bird Lake are the crown jewels of our city and that experiencing nature can change people’s lives, as it did hers when she started walking The Trail in 2000. She spends her free time pretending to be a Food Network Star, singing in her car, searching for perfect plant combinations, and road-tripping with her husband and two kids across the country (lots of times in a travel trailer).

Communications and Engagement Director

Mandi Thomas

Mandi brings over 25 years of marketing and event experience to The Trail Conservancy, having worked in both corporate and non-profit sectors. She has extensive experience in building and promoting brands and curating experiences through creative placemaking, programming, and events. Mandi is passionate about bringing the community together and believes that the Trail is one of Austin’s most important (and loved) public spaces – a place everyone uses for either emotional reprieve, to recharge through activity, or as a shortcut for getting from one place to the next. When she isn’t enjoying the Trail with her dogs, Mandi is most likely on the lake paddle boarding with her husband, singing and dancing with friends at a concert, or cheering on her teenage daughter.

Courtney loves to try new restaurants, read, travel, and watch live music when she’s not outside.
