Colleen DeLong

Habitat Stewardship Biologist

Colleen Delong helps coordinate the Riparian Conservation Program, works with Growing Native and Native Garden volunteers and assists with other conservation initiatives.

Colleen grew up in Lehigh County, Pa., swimming and canoeing in the Lehigh River and hiking on the Blue Mountain. She was first inspired to pursue a career in the natural sciences during an environmental science class in 11th grade. She earned a B.S. in Environmental Biology from Juniata College and an M.S. from Penn State University’s Ecology Program.

Most of Colleen’s work over the past 20 years has been in habitat establishment and conservation, along with education and outreach. Colleen comes to us from the PA Game Commission (PGC), where she was the statewide coordinator for the Wild Pheasant Recovery Program.

While working at the Cornell Lab of Ornithology, Colleen was the education coordinator for the Cornell Nest Box Network, a citizen-science program that taught people from all walks of life how to conduct wildlife research by collecting data on the success of cavity-nesting birds that use nest boxes across North America. She worked with the West Virginia DNR, assisting homeowners in the West Virginia Wild Yards Program to create backyard habitats for wildlife (and people too) and the Outdoor Learning Sites Programs, where she helped schools create wildlife habitat and outdoor classrooms on school property.

Outside of work, Colleen spends most of her time outdoors, gardening and hiking with her golden retriever and border collie.

Suzy joined Clearwater in July 2017 as the Conservation Projects Coordinator.

Suzy develops, manages and advances conservation projects in ClearWater’s land and water resources programs in collaboration with the Habitat Stewardship Biologist and Land Conservation Manager.

As an aquatic ecologist, Suzy spent the last 20 years studying riverine benthic macroinvertebrate ecology, conducting natural resource and water quality assessments and managing research projects for Riparia at Penn State University where she earned her B.A. in Wildlife and Fisheries Science and her M.S. in Ecology.

Suzy grew up and currently lives near Lewisburg at the foot of Buffalo Mountain in Central Pennsylvania along with her husband, Rick and sons, Caleb and Ethan. Outside of work, you’ll usually find her behind her microscope, tending her garden, hiking in the woods, or splashing around in the water.

Dan Trew

Americorps Adventure Coordinator

An aerospace engineer turned nature nerd, Dan graduated from Penn State and decided to stay local to be a part of the growing State College community—taking a tack of following his passions and not frowning at a computer all day.

Dan is an avid proponent of all things fun outside; hiking in the encircling state forests, canoeing on world-class streams, and rolling around in the snow pretending to cross country ski are some of the many activities he can be found doing. Equipped with a breadth of local outdoor knowledge and a life spent out-of-doors, Dan is the steward for growing the appreciation for and engagement in the local population for the natural resources ClearWater helps protect.
