Staff & Board
Karl has been involved in non-profit management, program development, and fundraising for twenty years. He began his career as the Environmental Programs Coordinator at The New York Botanical Garden in the Bronx where he worked with inner city teens, created an intern program, and managed a variety of public programs. He then was the Education Director at the Theodore Roosevelt Sanctuary and Audubon Center on Long Island. The programs he managed generated over $250,000 in revenue. While at the Sanctuary, he banded birds at a MAPS bird banding station and handled live birds of prey. From there, he moved to Seattle, where he led family nature hikes for a local hiking club, assisted with planning a regional wilderness conference, and taught children how to kayak. He also worked for a season at Mount Rainier National Park creating ecology programs for school groups, editing and field testing a geology curriculum for teachers, and leading old growth forest and alpine ecology interpretive hikes for all ages. Next, he went to Los Angeles to work in documentary film production, including work on the Disneynature film, Wings of Life. While in L.A., he also volunteered on projects for the protection of California condors, stream habitat restoration, and songbird banding in Zuma Canyon in Malibu. Currently, Karl is the Executive Director of the Audubon Society of Greater Denver. He is a member of the Nonprofit and Business Partnership at the South Metro Denver Chamber and a board member of the Colorado Environmental Film Festival. Karl is a Colorado native, and an avid hiker, mountain biker, snowboarder, cross-country skier, cook, gardener, and birder/naturalist. He also climbs a new 14er every now and then, and it is a fairly well-known fact he loves snow. Karl has been to 43 states – just seven more to go!! – as well as Canada, Mexico, Jamaica, Grand Cayman, Trinidad, New Zealand, and Iceland.
Emily B. Hertz, School Programs Coordinator
Emily moved to Colorado from Seattle where she graduated from the University of Washington with a Master’s of Education. In addition, she received a certification in Environment, Education and Community from IslandWood, a graduate environmental education program on Bainbridge Island, WA. Previously, she worked as a resource management and conservation project coordinator for the Tucson Bureau of Land Management/Student Conservation Association. She was also involved with the Tucson Audubon Society, where she took naturalist classes and created interactive education booths for their annual Ironwood Festival. Emily enjoys rock climbing, photography, trail running, camping, gardening, eating chips & salsa, and hiking with her fluffy tuxedo cat Murphy and her husband Steven.
Kate Hogan, Community Outreach Coordinator
Kate is a native of Tulsa, Oklahoma, where her love for the ocean took her to the University of Puget Sound in Tacoma, Washington. She studied abroad at James Cook University in Townsville, Australia where she went searching for the elusive cassowary (which she unfortunately did not find), but she did encounter the not-so-elusive kookaburras, wallabies, and possums throughout campus. Upon her return, Kate interned with the beautiful marine mammals and birds at Point Defiance Zoo & Aquarium in Washington. “You haven’t lived until you’ve bleached an ENTIRE puffin exhibit and shoveled polar bear poop!” She graduated with a Bachelor’s degree in Natural Science/Biology in 2005 and ironically could not find a job near the ocean, but the Denver Zoo hired her for a seasonal position with their Summer Safari camp. She was then hired as an educator for the Downtown Aquarium in 2006, a family programs specialist with the Denver Zoo in 2007, and as the education and group sales coordinator at the Downtown Aquarium in 2010. In 2012, she graduated from Regis University with a Master’s in Nonprofit Business Management, and although she will miss the sharks and mermaids dearly, Kate was so excited to once again be joining a nonprofit like ASGD that values environmental education and strives to teach the community about the beauty of Colorado wildlife. She currently lives in Parker with her husband Bryan, daughter Caitlyn, and son Luke.
Alex Collopy, Naturalist Educator

Rhonda Shank, Office Manager
Director of First Impressions for 15 years. She enjoys cooking, gardening, and searching for unique finds at local thrift stores and estate sales. If you’ve called the ASGD offices you’ve likely heard her friendly voice on the end of the line.
