Overview

Mission

The Friends of Peirce Mill, in partnership with the National Park Service and the wider community, work to preserve, restore, and interpret the last working gristmill in Washington, DC for the enjoyment, education, and inspiration of all generations.

What it reported doing in 2025

In cooperation with the National Park Service, recruit, train, schedule, and supervise volunteers to conduct tours of Peirce Mill on weekends. Support monthly milling operations by offering miller training for NPS staff, part-time contractors, and volunteers. Retain consultants to liase with the National Park Service.

Operating model

Revenue model
Mixed. Its operating money came from several sources; no one source provided a clear majority.
Distribution model
Direct operator. The filing allocates 100% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.

The verdict

STRONG - A large share of available resources goes toward mission work and the filed numbers largely add up. Some filing-based governance responses are negative or unanswered and liabilities are high compared with assets.
