David V. Brotman

Executive Director

A Virginia native, and graduate of Virginia Tech, David has broad experience in environmental field work, business, conflict resolution, and education.  Times spent in the Shenandoah Valley as a boy and young man — camping, hiking, fishing, and canoeing — are the very roots of his environmental interests, and his love of nature.

David is a natural public educator, and has taught all age groups in a variety of indoor and outdoor settings.  Subjects have included Chesapeake Bay ecology, Wild Edibles, and many more.  In Yellowstone NP, he trained citizen scientists in field data collection.

During a long stint in California, David logged more than 2000 hours volunteering on both public and private habitat conservation projects.  While on the west coast he also trained in conflict resolution where he practiced with Centinela Youth Services, and with the international mediation group, Mediators Beyond Borders.  Since his return to Virginia, he has been active with the Woodstock Tree Board, Front Royal/Warren County Tree Stewards, Coming to The Table workgroup on race relations, and has helped at both Seven Bends and Shenandoah River State Parks.

David continues to be an avid hiker, camper, outdoor educator, and hunter of wild edible plants.  He finds great joy in studying our woods, wildlife, and landscapes, including the unique and historic, cultural heritage sites still scattered throughout the Valley.

Kathleen Fish

Education/Science Program Lead

Kathleen began sharing her love for the environment in high school and went on to earn a Bachelor’s degree in Environmental Science from George Mason University and a Master’s in Environmental Studies and Communication from Prescott College. She has worked as an environmental educator and outreach specialist across the country, though her efforts have been focused on bringing people together in their love for nature. Kathleen enjoys hiking, kayaking, camping, and creating art while out on the trail.

Daisy Blakely

Education Support Specialist/ BMIM Program Lead

Daisy started at Friends in May 2019 as a summer intern after graduating from Shenandoah University with a B.S in Environmental Studies. She currently works as our education support specialist helping with a variety of programs. 

Her interest in the environment grew from a young age experiencing the outdoors on family outings while camping, kayaking, and hiking, which she still enjoys doing whenever given the chance. She is interested more specifically on enhancing water quality, learning more about benthic macroinvertebrates and what they can tell us about rivers, and educating others about the river and environment. 

Sheila Orndorff

Administrative Assistant

Sheila was born in Shenandoah County and raised in the Martinsburg/Winchester area. After moving
back to Woodstock, she met and married her now late husband of 25 years and raised two daughters here.
Before entering the nonprofit world, Sheila spent 12 years in a corporate office working as a
Transportation Coordinator. In September of 2000, she was hired as the Services Coordinator at
Shenandoah Alliance for Shelter (SAS). Five years in, Sheila was promoted to Executive Director at SAS where she maintained that role until her retirement in September of 2021. A very short time later
though, in Spring of 2022, Sheila began working with FNFSR as our office administrator.
Sheila volunteers for the Shenandoah County Chamber of Commerce as Chair of its Nonprofit Council.
She is very committed and involved in helping our community, and she often takes on other volunteer work to help. Sheila enjoys traveling and spending time with her family and friends; working part-time with FNFSR has allowed her to keep family as a top priority.


Friends of the North Fork engages the enthusiasm of scores of volunteers who provide hundreds of hours of support to our mission — and the health of our river — every year.  We could not do it all without them!

Our volunteers do the dirty work and have a lot of fun in service to the river.
