The Pastors & Staff that make everything at the hill possible


"We will tell the next generation the praiseworthy deeds of the Lord, his power, and the wonders he has done."
— Psalm 78:4

Karin Mazzeo

Next Gen Pastor

Hi, I'm Karin. I’m the Next Generation Pastor here at Church on The Hill. I started here 15 years ago as the Children’s Pastor and have been serving ever since. I'm a transplant from the Chicagoland area who made Southern California home when I married my husband, Alex. He and I live in Riverside with our dog, Watson. I went to school in Illinois, obtained my BA in Sociology and then worked in the social services/nonprofit arena for several years while volunteering at my local church. God then called me to vocational ministry and I went to seminary at Dallas Theological Seminary, graduating in 2003 with a MaCE. I was ordained in 2018. In 2017, I became the Next Generation Pastor here and now have the opportunity to work with a great staff and awesome volunteers, overseeing our ministry from birth through to young adults. I also get to lead a women’s bible study every Friday. When I’m not working, I love music, art, reading books and drinking coffee with friends.
