Rhonda Shank, Office Manager

Rhonda Shank

Rhonda has been the “Director of First Impressions” for over 17 years at Denver Audubon. She manages all office operations, including database management, bookkeeping, program registration, assisting with special events, and customer service. If you’ve called the Denver Audubon offices, you’ve likely heard her friendly voice on the other end of the line. She hails from the beautiful Amish country in Pennsylvania. She enjoys cooking, gardening, genealogy, and searching for unique finds at local thrift stores and estate sales. Although Rhonda has been an outdoor enthusiast all of her life, she has gained a new appreciation for birds and other wildlife since she began working at Denver Audubon. She currently lives with Charles, two cats, and two dogs.

Kate Hogan,  Community Outreach Coordinator

kate-hogan-225x300Kate 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 Denver Audubon 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.

Andy Carstens, Communications & Marketing Coordinator

Andy moved from Chicago to Denver in 2017 to be near the mountains and to have more time in nature. Before relocating to Denver, he worked in and managed an environmental group at an engineering company, where he focused on air and water quality issues. Early on, his engineering career took him overseas for several years, living in Egypt, Turkey, and Spain. This international experience opened his eyes to different cultures and perspectives, and he and his partner continue to cultivate a shared love for travel to anywhere they’ve never been. For the last year, Andy wrote and edited for a consulting firm, mostly covering environmental topics. He’s also pursuing a master’s degree in science writing from Johns Hopkins University. It was a nature writing school assignment that first brought him to Denver Audubon, where he inadvertently landed in a birding insights class that enlightened him on many levels, including teaching him that a “bufflehead” is not a synonym for a dullard. Andy enjoys many things, but road cycling, hiking, skiing, reading, and writing are high on the list as are eating and drinking with friends.
