Gabby & Mateo Alzate, YWAM San Francisco

Mateo and Gabby Alzate have been with YWAM since 2010.

Ever since they were serving in different YWAM Disciple Training Schools in different locations, God had been working in their hearts to root them both in San Francisco as long-term missionaries. They got married in April 2017.

Gabby joined staff with Because Justice Matters (an extension ministry of YWAM San Francisco) in 2012, launching programs for young girls in the Tenderloin. When Mateo came to YWAM San Francisco in 2017, he began a complementary ministry working with young boys in the families which Gabby and BJM had been ministering to for years.

Together, Gabby and Mateo work to help prevent cycles of violence and challenges many children and youth face while growing up in urban communities. They believe God is reviving hope and bringing lasting transformation in the lives of the next generation.

We asked them a few questions about their work, and here’s how they responded:

What do you love about this work?
“I would say both of our greatest joys is being able to see kids find life in Christ and have hope for the future. We love seeing God revive dreams in the lives of kids and their families, and to see them believe again for the good plans that He has for them. We believe that new life is being breathed into the lives of the next generation of influencers and world changers, and we are excited to be part of it!”

Describe something God has shown you during your time as missionaries.
“We are learning all the time what it means to completely trust in God. He is constantly showing us deeper places where we can trust Him more and surrender new places in our hearts. Whether it’s trusting Him for the healing of people’s hearts, our finances, or anything in between, He is showing us His faithfulness and goodness.”

What has been your most memorable experience  so far?
“Every summer, we get to take a group of teenagers from the Tenderloin out on a week-long houseboat trip. This past June was particularly memorable. It was such a powerful week where there was salvation, freedom from bondage, genuine, pure worship, and so much joy! We could go on and on about how brave each kid was in choosing life, forgiveness, and courage!”
