For the 1st 39 years, the independent San Gorgonio Pass Memorial Healthcare District operated the hospital through a 5-member, elected district board. In 1990, the hospital operations were assumed by the newly formed San Gorgonio Memorial Hospital Corporation, a nonprofit public benefits entity. The corporate board of 13 members, including the 5-member district board, was formed. The San Gorgonio Memorial Healthcare District remained as the owner of facilities leased to the nonprofit operating corporation.
