Welcome to Cornerstone Fellowship! Serving the Diablo Valley, we hope you feel welcome and at home. We want to do whatever we can to help you, your family, friends, and community experience Jesus and live a life on mission with each other. The way forward is together! 


10 am - Indoor Gatherings*
*Note: Every other month, we meet in Neighborhood Churches. 

535 Walnut Avenue, Walnut Creek, CA

Or, if you are unable to join us in person, you can connect with CF Church Online every Saturday and Sunday. 


Neighborhood Church

Mark your calendars!
Sunday, December 4th we’ll be hosting Neighborhood Church in homes near you! Instead of gathering in our building, we will be meeting in homes spread out all around the valley. We do this regularly because it's a great way to connect with people in our church community who live near us. As we build friendships within our neighborhood, it becomes easier to include and invite other neighbors who don't know Jesus yet. And it's a much more effective way to hear and understand what's going on in each other's lives so we can actively care for one another. We'd love for you to join us for Neighborhood Church on Sunday, December 4th.

Kids and Youth

If you have (or are connected to) a family with young kids, lower or upper elementary-aged kids, or even Middle school and High School students, we want to partner with you!


Mental health is in the headlines daily, and as a church, we need to be in the conversation. Jesus cared for many who struggled with mental health, and His example of caring, supporting, and healing is one we can and should follow. In a recent sermon series, we started the conversation about: addiction, grief, co-dependency, anxiety, and depression.

Our hope and prayers are that anyone who is or knows someone who is struggling with mental health, including mental illness, can find the support and resources they need to obtain hope, health, and healing. A list of resources has been compiled to help this journey. 


Meet the Staff

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.

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.
