Construction of the first church began in January 1956 on a 2,000 sq. m lot donated by Philamlife Insurance Company, with a starting cash fund of PhP 30,000.
Additional funding came from Rufino Cardinal Santos, homeowners, raffle proceeds led by Mrs. Amelia V. Borromeo, Sunday collections, and donations.
Sta. Rita de Cascia parish was canonically established on May 31, 1957,
becoming territorially independent from its mother parish, San Pedro Bautista parish in San Francisco Del Monte.
