About William & Lily
Our names are William and Lily Silverthorn. We’ve been married 31 years (as of November 2026). We moved to San Diego in 2005 with the birth of our oldest grandson, Nico Waning. We have been members of the Branch Church (& “Pocohontas”) since living here. We have 12 grandkids ages 5 to 31. 5 of our 6 children (and all grandchildren) are in LA, Orange, Riverside, and San Diego counties.
We’ve both been very active with our faith before we found each other. For the last nearly three decades together we have been very active both in LA as well as San Diego leading bible studies, hosting home fellowships, promise keeper ambassador work, intercessory prayer, 5 years working in elder care ministry with Tony, and more. We have been active with Branch church and its origins for 22+ years in San Diego.
Lily retired from working with the State of California primarily working in architecture and contractor licensing, but also received a Juris Doctorate in Law in her spare time. William retired from 35 years in the computer industry, with much experience in technology systems, sales, management and marketing, with the bulk of those years being with IBM. With Chuck Allers’ encouragement, William most recently (2025) received a Master in Biblical Studies & Biblical Counseling from CCU (Calvary Chapel University).
With retirement, we turned to the missionary field, planting a church and youth ministry that opened its doors in 2013, later adding Youth with a Mission (YWAM) in 2018, a teaching school of University of Nations (UofN) graduating students from Discipleship School in 2019, 2021, 2023, 2024 & 2025.
Our 17 years working in Peru has stretched us greatly to serve more every year. We have added facilities, ministries, lodging, staff, farming, and many relationships. We have stretched our outreach often beyond our immediate focused villages to Bolivia, Brazil, Ecuador, Mexico and USA. We have attracted missionaries from around the world, greatly via our YWAM affiliation and teaching. Much is left to do with current plans to plant more churches and even a school.
It is time we turn over the reins to the next generation to continue to grow this ministry. Help us to recruit the right people, short term or long term. Thank you all for partnering with us.
Today (2026) they have an active Mission, 2 building campus, with a 3rd building for marital staff housing. Also a small farm close by and two expansion properties praying to add 2 more churches AND a school.
They are engaged in 6 unique villages helping a large number of needy families with a volunteer staff of 10+ individuals. 8 years ago, in 2018, they added a Discipleship school in partnership with University of the Nations (YWAM) and have been attracting young missionaries to assist. All of the above is to focus on the great Commission in this area of need, prayerfully to turn these needy people into disciples of Jesus.
