St. Timothy's is part of the Diocese of El Camino Real. Several members of the parish serve as elected or appointed officers within the diocese.

The Diocese of El Camino Real stretches from just south of San Francisco to just north of Santa Barbara. Once part of the Diocese of California, the congregations of El Camino Real, formed in 1980, are found in the five counties of San Benito, San Luis Obispo, Santa Clara, Santa Cruz and Monterey. Although the youngest diocese in California, ECR's Trinity Cathedral, in San Jose, is the oldest cathedral structure in the State of California.

El Camino Real, named not for a city or state but after the Spanish colonial road from Mexico City to Oregon, is a diocese of 56 congregations, one upper school (York) two K-8 schools and nine pre-schools (including St. Timothy's Preschool). The diocese worships in seven languages: Cantonese, English, Lakota, Laotian, Mandarin, Spanish, Tagalog and Vietnamese.
