Who We Are

Our Staff & Elders


Staff

Cornerstone's staff is comprised of our pastors, ministry directors and administrators. They serve together with lay directors to oversee major ministry areas to fulfill the overall mission of the church.


Joe Yoshihara

Lead Pastor

I was blessed to grow up in a Christian home and because of this I've always believed that God existed and cared about me. I made my initial commitment to Christ at the age of 14 at a Billy Graham crusade at the Kingdome. After drifting aimlessly in my faith for several years I recommitted myself to Christ as a senior in high school. The Lord used Rita, my future wife, during this time to get me back on track spiritually and I was baptized in 1980.

After graduating from UW in 1985 I lived in Southern California where I attended Cerritos Baptist Church, became their director of college ministries, and had the initial seeds of starting a church planted in my heart. In 1990 I returned to Seattle to marry my high school sweetheart, Rita Locke, and after spending seven years in the business world I felt led by the Lord to pursue Christian ministry so I enrolled in Western Seminary in 1992. In 1996 we planted Cornerstone and the Lord has blessed us with a wonderful church family and four beautiful children, Matthew, Michelle, Kellie, and Kyle. I love being a husband and a dad and when I’m not with my family I enjoy playing hoops.

Warren Eng (on sabbatical until 9/2/17)

Pastor, Equipping, Family & Growth Groups

The first big step in my journey with the Lord came in the 8th grade when I started attending Chinese Baptist Church in Seattle to find answers in life. I knew little about Christianity so I sat week after week learning more about our triune God. I eventually agreed that Jesus was who he said he was and received him as my Savior in my senior year in high school. It has been a great ride ever since!

My journey into full-time ministry was a longer one, with a few twists and turns. I first went to seminary in Vancouver, B.C. (Regent College) in 1997, received my diploma in Christian Studies, and then returned to the Seattle area. After getting married, I felt God leading me to return to seminary part-time (while working full-time as an engineer), this time at Fuller Theological Seminary’s Northwest extension in Seattle. Early on there I felt a clear call to full-time ministry, I completed my studies in July 2007, and was blessed to be called to be Cornerstone's first youth pastor! I changed roles to Discipleship pastor in 2012, and enjoy discerning how we can best grow passionate followers of Christ.

Anton Lee

Pastor, Worship & Community Life

I began attending church at the age of seven for two simple reasons; to hang out with my church friends and to eat the free church lunches! I kept that carefree attitude over the next several years until some traumatic events occurred in my life, including my father’s sudden passing. I then went through an extended time of isolation, desolation and desperation until the day God’s abundant love and mercy overwhelmed me and I accepted Jesus Christ as my personal Lord and Savior. Ever since then, He has continually been my fortress of strength, the Rock of my salvation and the Faithful One in every aspect of my life.

In 1999, the Lord called me into full-time ministry and I decided to go back to school again (ugh!). However, His grace remained prevalent upon me, as I was able to graduate from Fuller Seminary with a passion for worship ministry. It is my desire to seek after God’s heart in the hope that He would be able to continually transform my own heart into one of worship.

DeWayne Strange

Pastor, Student Ministries

I grew up in a Christian home in rural Washington, accepted Christ and was baptized in 1990. I was the typical “church kid.” I knew just enough about God to float by without anyone noticing that I had no real relationship with Him. During my senior of high school, I encountered Him in such an unmistakable way that I surrendered my whole life to Him as well as the call to ministry. I attended Saint Martin’s University where I began serving with Young Life, and in 2004 became a full-time children’s pastor and enrolled in the M. Div program at Golden Gate Seminary. In 2007, I moved to San Francisco to finish my studies, where the Lord led me to serve as the pastor of a Korean-American congregation in Richmond, CA. In 2008, I met my wife Jessica, who had been serving as a missionary in inner-city Oakland. We were married less than a year later and life has been amazing ever since! In 2012, though an amazing journey in faith, God called my family and me back to the Northwest where we found a home here with our awesome brothers and sisters at Cornerstone!

When I’m not telling teens about Jesus or making them do crazy games involving eggs, baseball bats and shaving cream, I’m probably out hanging with my beautiful wife Jessica, our three sons, Connor, Tristan and Declan.

Emi Locke

Church Administrator

I was born and raised in a non-Christian home in Vancouver, Canada. When I was in Grade 5, I accepted Christ at a summer Bible camp with a school friend, but I have walked away from God many times. When I went to university, I studied anthropology and sociology and it made me question whether there really is a God or whether man believes in God because he needs something to believe in (since all societies believe in some sort of religion.) This was a major roadblock for me in truly believing in Christ as an adult.

I married Derek in 1995 and moved to Seattle, WA where I continued my career as a legal secretary until we gave birth to our first child, Tyler. My husband and I were invited to Cornerstone by Derek's cousin, Joey Locke. After attending church for a while, I attended various Discovery and small groups. During Pastor Joe's Discovery Group, we talked about the fact that it's difficult to prove God exists with physical evidence, because God is an all-powerful entity and He is not of this world.

Around this same time, I heard some amazing testimonies during church services and many sermons spoke to me. I would cry during service and not really understand why. Also around this time, the movie “The Passion of The Christ” came out. I decided to go see it on my own. What we did to Jesus was horrific, but after all we did to him, Jesus still prayed to God and asked Him to forgive us, because we didn't know what we were doing. I knew Jesus was not an ordinary man and He was not of this world. He is the son of God.

I re-dedicated my life to Christ with my friend Susanna Hui shortly after that. It wasn't a movie that made me believe; rather, it was seeing what Jesus went through to save us that made me truly believe that Jesus is the son of God.

Elders

Elders are the overall spiritual shepherds of the church. These appointed men strive to exemplify a Christ-centered life as they lead, feed, care for, and protect the church. They ensure that our church is led by the Holy Spirit to apply and fulfill its mission, is biblically sound in our teaching, and guard against spiritual assault and division. The elder team is led by Pastor Joe Yoshihara and has final authority in all matters of the church.

Duane Okamoto

Elder

I grew up mainly in Southern California and was in junior high school when I attended my first Christian camp retreat. I was not a Christian, but witnessed the power of God when we prayed for healing of someone too sick to attend because he was diagnosed with stomach cancer. By the end of the retreat, we learned that he had been miraculously healed, and he was released from the hospital. Shortly afterwards, I accepted Jesus Christ as Lord and Savior of my life. From that time, I have been growing in my faith and knowledge of the Lord through His Word.

Once I completed grad school and was working for a few years, I met and married my wonderful wife Linda. We have raised four terrific kids together – Stephen, Michael, Sarah, and Allie. After residing in Orange County, California for several years, we believed that God was calling us to be in the Seattle area, so in 2008, we moved to Washington, and now call Issaquah, WA our home. The word we received from God is that we are called to “change the culture.” Since we have been here, we have seen this word become truth in the workplace, at church, and in our community. Praise God! And, we know there is immeasurably more to come!

God has been gracious to us by allowing us to become a part of the Cornerstone family. We feel blessed to be at Cornerstone, where we see and feel God’s love towards others, we are living out the Lord’s command in Matthew 28 to make disciples of all nations, and we are growing in our relationship with God and Holy Spirit.

Patrick Yamashita

Elder

I graduated from Washington State University in 1987 with a degree in civil engineering after living several years of college fraternity life. In 1991, I made my faith commitment to the Lord while attending a church service in an old theater in Honolulu where God started a lifelong transformation of my life. He made himself real in the days that followed when he removed my uncontrollable desire to drink. I met my wife Laura a year later. We married after three years and now have two boys, Ethan and Noah, who can warm even the saddest heart with their laughter and smiles. Laura is my greatest supporter and the joy of my life. I enjoy gardening, cooking, woodworking, and being a father.
