Michelle Kokolis
Watershed Restoration Project Manager

Michelle has spent all of her life in and around water. She grew up in a small town just north of Pittsburgh, PA, along the shores of the Allegheny River. If you ask her mother, she will tell you that it has always been nearly impossible to keep her out of the water! Annual family vacations were spent camping and bass fishing in Canada, which is where her love of nature photography began. In college and graduate school Michelle studied phytoplankton and she continues to be fascinated by the microscopic things in the water that we can’t see. One of Michelle’s favorite pastimes continues to be nature photography. Whether she is on the water or on the shore, you will always find her with her camera!

Prior to joining the staff at JRA Gabe was leading wilderness trips and activities at a school for troubled teenage boys. He earned a bachelor's degree in Environmental Thought and Practice from the University of Virginia, while working as a field instructor for fly fishing programs and directing a volunteer program dedicated to affordable housing. He grew up past the headwaters of the Rivanna, up the Mechums River, where he fell in love early on with the rivers and woods and later developed what was for a time an unhealthy obsession with fly fishing for trout. He is very grateful to be working alongside other people who are so passionate about protecting and restoring the James River.

Judith Warrington
Communications Coordinator

jwarrington@jrava.org
Judith grew up in a river town on the Eastern Shore and would never consider living anywhere that wasn't on a river. Today she lives within a few short blocks the James. Originally an archaeologist, her career path has taken her from magazine editor, to freelance writer, to fundraiser. That meandering path probably has something to do with her love of hiking, backpacking and wandering in general. At JRA she is responsible for grant writing, publications and membership. She holds a BS in Anthropology from The American University in Washington, DC, and would have completed an advanced degree at Eastern New Mexico University if there had been a river anywhere nearby.
