Leadership

Pastors, Staff and Elders

Joe Yoshihara

Lead Pastor, Elder

I have the privilege of serving as lead pastor since the inception of Cornerstone. My wife, Rita, and I have four children (Matthew, Michelle, Kellie, and Kyle).  We also have a dog – Toby.  Each of the kids think they are my favorite but it’s really Toby.  He’s always happy to see me, he’s never in a bad mood, and he licks my nose.  I say it’s a sign of affection, but my kids say it’s his snack.  Enough said.  Rita and I enjoy serving together, especially walking alongside married couples.  Playing basketball and pool are fun ways I relax and connect with people, both inside the church and outside of it.

Anton Lee

Pastor, Worship & Compassion

I have lived in Seattle since early childhood, graduating from UW, and have worked in a variety of different industries, including: video games, coffee, cellular and jewelry!  At the age of 29, however, I felt called to vocational ministry and attended Fuller Seminary. After completing my Masters degree in Theology, I joined the Cornerstone staff in 2002 as the Worship Pastor, as well as overseeing our Compassion Ministries. I enjoy playing music & sports, movies & food!  I am blessed with my wife Karen, and our two sons, Caden and Jordan.

Daryl Siu

Pastor, Community Life, Hospitality, and Communications

I’ve been in the Seattle area for my whole life and love it here.  I graduated from Seattle Pacific University in 2007 and previously worked in IT at SPU and at Microsoft.  After coming to Cornerstone in 2013, I helped lead a few different community groups (CGs), eventually serving as the lead for young adult ministry.  In 2019, God called me to join Cornerstone staff as the Pastor of Community Life, where I get to help grow our CGs in discipleship and their love for God.  I met my wife Lisa on a Holy Land trip with Cornerstone in 2016, we got married two years later, and currently live in Bothell with our son Dylan.  I am a former competitive swimmer who loves board games, Marvel, UCLA, soundboards, Star Wars and Trek, biking and both real and fantasy football.     

Micah Clark

Pastor, Student Ministries

I grew up in Southern California, Moreno Valley to be exact. My parents were pastors so I had the privilege of seeing God’s handiwork up close. Prior to following the Lord’s heart into vocational ministry, I was a firefighter for 8 years in the Carolinas. In 2020, I joined Cornerstone as a pastor to oversee the youth ministry. My wife Taryn and I are high school sweethearts and we have 3 kids: Micah, Alexander, and Phoenix. When I’m not working, I enjoy listening to music and spending time with the fam, date nights with the wife, working out, playing basketball or soccer and watching the only basketball team that matters, the Los Angeles Lakers!

Takumi Gotanda

Pastor, Cornerstone Tokyo

I love to laugh, but I am not good at making people laugh while delivering sermons.  I would like to get better at it though!  I have a wife Mai and two daughters.  It has been 20 years since I have moved to Tokyo for my college.  I like the culture and food here, and living in Tokyo gives me a chance to meet with many new people.  Right after my college, I worked as a community liaison connecting children with local communities.  After that, I started serving in Cornerstone Tokyo.  I love to support the young generation like me as redeemers and passionate followers of Christ, and I have a passion for witnessing people change.  The life Jesus gives us is without limit, and it is the best gift. 

Derick Domae

Pastor, Cornerstone Tokyo

Originally from southern California, I moved to Tokyo, Japan as a missionary in 2009. I joined the Cornerstone Pastoral leadership in 2016,  where I help to disciple people to a deeper and intimate relationship with Jesus. My heart is to see Japan reached. I believe in stopping for the one. This means that discipleship is more than just teaching people from a distance, but investment into each person’s life. As people fall more in love with God, and begin to live out their freedom in Christ, they will share their faith with others in both speech and conduct. Though I graduated from CalState University Fullerton with a major in Illustration, I am currently studying at Eternity Bible College as a part-time student in Biblical Studies. For fun, I enjoy conversations and meals with people, playing board games, Disneyland, the gym, and studying Japanese. 

Emi Locke

Church Administrator

I’m originally from Vancouver, BC, Canada.  I worked as a legal secretary until I moved to Seattle in 1995 when I married my husband, Derek.  We are blessed to have 2 young adult children, Tyler and Melanie.  I accepted Jesus at a summer Bible Camp in grade 5, but by middle school, I walked away from the Lord.  By university, my anthropology and sociology classes made me question whether there was a God or whether we as humans just need to believe in something.  I have been attending Cornerstone for approximately 20 years now, the last 10 of which I’ve had the honor of serving as Cornerstone’s Church Administrator.  I am so very blessed to serve alongside our Pastors, Elders, staff and Cornerstone family.  Each day I am able to receive more of God’s love and grow in my identity in Christ as we study His word.  I love prayer ministry, listening to worship music, traveling, watching movies, dancing, hanging out with my family, friends and our dog, Russell!

Rita Yoshihara

Student Ministries Administrator

Growing up in Seattle, this is home.  I've had the blessing of living in the LA area twice in my life, where God used those experiences to strategically shape my faith. Starting Cornerstone with Joe was definitely faith building and stretching for me, especially because we started the church with a toddler and an infant (Matthew and Michelle).  Shortly after, we had 2 more kids (Kellie and Kyle). After 30 years of marriage, 4 kids, and almost 25 years of full time ministry, we've never looked back.  God has taught me so much along the way.  He is faithful, and truly amazing!  I enjoy meeting with and walking alongside younger women in their journey of faith and life, event planning, and listening to worship music!  

Duane Okamoto

Elder

Growing up and Encountering Jesus – I grew up in the land of sunshine and beaches, near Los Angeles in Orange County, CA, and first experienced the love and power of Christ a Christian camp during middle school – I didn’t know him personally yet, but prayed in my cabin for a brother of one of the guys who had stomach cancer, and received word of his complete healing by the end of that week!  Since there are no coincidences in God’s economy, I accepted Jesus Christ as my Savior and Lord, and have been growing and following Him ever since.  School, Work, and Family – After college at UCLA (Go Bruins!) and USC for law school (Go Trojans!), I met Linda (my wife) at a bible study at a home in LA rented by Pastor Joe at the time (again, no coincidences with the Lord!)  In 2007, after seeing myself as Peter stepping out of the boat when Jesus said “Come,” we decided to move to Washington.  As we were confirming our call to the PNW, prophecies prayed over us included being part of a revival fire occurring on the west coast up through the PNW, and that in my life here, I would be a “changer of culture.”  Linda and I moved here with 4 terrific children – Stephen (now living in LA), Michael, Sarah, and Allie.  Life with the Spirit – We have been blessed with Cornerstone as our home church since moving here, and through our community of passionate Christ followers I have experienced the joy of journeying and deepening my relationship with Holy Spirit, to live a life of love, power, and freedom bringing the aroma of Christ and good news to my family, church, neighborhood, workplace, and beyond.  Now I’m living in the land of His presence (and a lot of rain!), where mighty things are happening in His name.  God is awesome!

Mike Tam

Elder

I had a radical encounter with Jesus during my freshman year of college at UCLA (Go Bruins!), and my life has never been the same since. I have been in the Cornerstone family for the past 20 years, and, together with my wonderful wife, Patti, help out with the missions team, Cornerstone Tokyo, compassion ministry and international student ministries. Abba's love is the best, and I just want more and more people all over the world to go deeper into that trans-formative love with them by the power and presence of God's Spirit.

Robert Unoki

Elder

I grew up in a small plantation town on the Hamakua Coast of the Big Island of Hawaii and while I attended church my faith really grew in my early 20s alongside my life and ministry partner, Tracy. Tracy and I, along with our three children, Taylor, Elisa and Micah have called the Seattle Eastside area home since 1995. I love outdoor recreation, our Cornerstone family, and of course, my Lord and Savior Jesus Christ.  Serving in the prayer ministry and overseas has been an extra special blessing for both Tracy and I.  We love our Cornerstone family deeply and are so grateful to have a great church home.

Tim Ng

Elder

I grew up in Toronto, Canada and graduated from the University of Waterloo, where I met my wife, Joyce, while serving in a campus fellowship. We settled in the Seattle area after a brief stint in Asia and decided to make Cornerstone our home shortly afterward. My personal ministry has focused on encouraging people to have a deeper, closer, and more intimate relationship with Jesus - to know him more and to experience his love for us in a real, tangible, and amazing way. I enjoy reading, playing piano, playing hockey, snowboarding, and learning random things in general! Joyce and I have two kids - Lucia and Milo, who continuously help me grow in understanding how deep the Father's love is for us.
