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! As guidelines continue to shift, so do our Kids and Youth experiences. Stay tuned for campus-specific details as we begin to regather indoors.

Online Experiences: Every week, our CF Kids and CF Youth teams put together amazing ONLINE experiences for families (preschool, elementary, pre-teen) and youth (middle school and high school) that you will not want to miss!


 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 Care Support and Recovery Groups to Online Community Groups, study guides, and daily devotionals, we are here for one another.

Watch On-Demand

Unable to join us in person or online during a live service time? That's okay!
Our Church Online weekend services and sermons are also available on-demand.

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.

Griffin Smith

I grew up in the Bay Area and have been on staff with Cornerstone at the start of 2020! Working with CF Youth is a passion of mine and I'm thankful to be working with such a great team and a GREAT group of students. Music is a huge part of who I am; You'll often find me with a guitar or behind a piano or with a microphone. I love a good pesto pasta and definitely avoid anything with curry in it.
