About the Board of Directors
The San Mateo County Horsemen's Association Board of Directors consists of interested people from our equestrian community and beyond.
The Board volunteers its time in providing educational training/events, horse shows for all levels of riders, trail rides and trail maintenance, and social events to San Mateo County and surrounding communities.
Members are elected to the Board at the club's Annual Meeting in November, and their term in office begins at our Installation/Gala held each January of the following year.
