PHPA was founded in 1995, as a social nonprofit organization to promote the preservation of open spaces and the creation of horse facilities in Pasadena, Maryland.  It has also served to stimulate the interest in horses, horsemanship and horseback riding as a recreational activity to all local area families.  Since inception, the volunteer members have organized horse related activities such as clinics, trail rides, photo contests, fun horse shows, youth riding camps, fund raisers, and guest speakers at their monthly meetings.
