Let's meet some of the staff who make Crabtree Nature Center great, starting with our current director. Jeff Rapp has been the director of Crabtree Nature Center since June 2008. He joined the Forest Preserves in May of 1990 with an internship at River Trail Nature Center. Throughout his years of service, Jeff has been instrumental in sharing his passion for natural history with the public. He is a "jack-of-all trades" with knowledge that spans both flora and fauna, and in the summer, he loves sharing his knowledge of cicadas and bats. Jeff is here most days, so don't forget to say hi, and feel free to inquire about any subject related to Crabtree or the Forest Preserves.
