Board of Directors & Staff

The Board

The Washington State Horse park is governed by an eleven member board comprised of individuals representing the horse community from various disciplines and geographic regions. The Board positions are filled by those who are passionate about realizing the Park's mission and who are willing to serve using his or her skills to improve Park operations.

State Charter and Leadership

In 1995 the Legislature authorized the Washington State Horse Park legislation which states, in part: "Establishing a first-class Horse Park facility in Washington would meet important needs of the state's horse industry, attract investment, enhance recreational opportunities, and bring new exhibitors and tourists to the state from throughout the region and beyond. A unique opportunity exists to form a partnership between state, county, and private interests to create a major horse park facility that will provide public recreational opportunities and statewide economic and employment benefits."

The complete legislation is in the State Charter document; its key provisions for leadership and direction are outlined below.


The legislation established the Washington State Horse Park Authority (“the Authority”), with an eleven member volunteer board of directors. The Authority is responsible for developing, promoting, operating, managing and maintaining the Horse Park. The legislation provides that the governor appoint board members from across the state experienced in different horse disciplines, activities and professions that compliment the development and operational needs of the Horse Park. Also included are a representative from the Washington State Parks Commission and a director who represents the local interests of the community where the Horse Park is located.

The Authority Board is supported by an Executive Director, Leslie Thurston, who provides day-to-day guidance, coordination and administration for their activities. See Staff

The Horse Park is currently supported by a small paid staff consisting of a full-time Executive Director, full-time Marketing Coordinator, and part-time Administrator/Membership Coordinator. While the Park is open, we also employ grounds staff.

We rely on a network of valuable volunteers who provide their services in various ways – from Board membership to licking envelopes. The Horse Park will always be reliant on volunteers to help keep costs down and to obtain needed skills when and where needed. Please visit the Volunteering page to see what opportunities are most critical.
