Concerts by the Orange County Philharmonic Orchestra were free to the public, funded entirely by donations from sponsors and memberships. The orchestral musicians agreed to donate their time for rehearsals free of charge with the permission of their union local stewards, while receiving a fee for the performances as Belinfante herself did. Belinfante insisted on this arrangement with sponsors, and that all concerts remain free of charge for all future attendees. The founding board of directors adopted Belinfante's suggestions as their business plan with the stated mission of maintaining a resident professional orchestra in the county.
