Walnut Creek Campus


Welcome to our Cornerstone Fellowship Walnut Creek Campus! From the moment you join us, we hope you feel welcomed and at home. We want to do whatever we can to help you, your kids, your friends and your neighbors take their next steps with Jesus, whatever they might may be. Due to the “shelter in place” orders in effect, all of our locations are currently closed. However, church is STILL happening.



Church is still happening even though our buildings are closed. Our services stream LIVE online every Saturday at 5pm AND Sunday at 9am and 11am. Join us from wherever you are!


Unable to join us during our live streaming times?
Our weekend services are also available on our YouTube channel!

Every week, our CF Kids and CF Students team put together amazing ONLINE experiences for families (preschool, elementary, pre-teen) and students (middle school and high school) that you will not want to miss out! Check them out!



Due to the “shelter in place” orders in effect, all of our locations are currently closed. We will not be gathering in our buildings until further notice.


 We are HERE for one another! 

Our Care and Community Teams have and will continue to build resources and opportunities for you to stay connected during this time...all ONLINE! From prayer to connection with a pastor or lay counselor. From Crisis Support Groups to Online Community Groups, study guide and daily devotionals, we are here for one another.


CF Kids is a fun and engaging environment that your kids will want to come back to again and again. It's free, safe and secure, and offered during all weekend services for kids ages 6 weeks through 5th grade. Our goal is that we help your child take their next step with Jesus.

Adrian Tsingaris

I was born and raised here and love the San Francisco Bay Area. Tonya and I have two super fun kids. I used to love scuba, reading, travel, backpacking, motorcycles, and eating out. Now, I mostly love coffee. I’m one of those weird folks who loves school, and I wish I could go back to San Francisco State University, Western Seminary, and Bethel Seminary. But, just do not ask me to do math.

Enoch Chang

I grew up in Charlotte and Atlanta and moved to the East Bay in 2016. I’m a loyal Atlanta sports fan so I’m used to disappointment and heartache. I have a biomedical engineering degree from Georgia Tech and a Masters in Divinity from Columbia Theological Seminary. I played the purple ranger in the un-aired Guatemalan version of the Power Rangers, or, Guardabosques de la Energía. I love exploring the bay area and wondering what new food they will attempt to fuse with Asian food next.

Lauren Strom

I serve as the Administrative Team Lead, which is a fancy name for keeping the Walnut Creek office from catching on fire and helping other Ministry Leads get stuff done. I was born and raised in the suburbs of Chicago, Illinois and am a proud alumnus of the University of Illinois-Urbana Champaign. I am married to my techie husband, Matt and have one furry child, Benny the beagle.

Amber Kotowski

I grew up in Livermore and started attending Cornerstone Fellowship when I was in high school (wow, I feel old!). God has always called me to work with children, and I was an elementary school teacher for 9 years prior to starting at Cornerstone in 2016. It has been a whirlwind of fun since then! My family and I reside in Walnut Creek and love life with our two adorable little boys and wonderful dog.
