Ryan Collister

Having worked in various positions at the Science Mill since 2019, Ryan Collister is currently the Living Exhibit Manager, responsible for overseeing all of the creatures you see on display or in our educational programs. With a particular focus in herpetology (the study of reptiles and amphibians), Ryan has held a keen interest in the natural world since a young age. After graduating with a Bachelor's degree in Organismal Biology in 2014, Ryan has worked in several educational roles, but most prominently as an Animal Care Specialist within the Herpetology Department at San Antonio Zoo for several years. The natural history of Texas is Ryan's favorite subject to share with our guests, and he can often be found outdoors in search of wildlife to document and photograph - especially rattlesnakes!
