Leadership

Pastors & Staff

Billy Claudio

Lead  Pastor

I was born in Chandler, Arizona to an Air Force pilot father which was the beginning of my adventures in life. I spent my early years in Europe until we planted in Long Island, New York where my dad was born.  This is the place my relationship with God began, at a little Bible study my mom and I attended.  This decision revolutionized how I viewed life and my purpose. After graduation, I attended New Life Bible College in Tennessee where I help establish the traveling theater group known as The New Life Drama Company (1983).  I traveled around the country and world sharing the hope found in Jesus. I met my wife while traveling and have been blessed to share 29 years of marriage with two boys and now a beautiful granddaughter and daughter-in-law.
I am an avid golfer and love spending time with my family especially when we are out back grilling steaks and just hanging out.  My wife and I love the beach and anywhere warm.
Dawn and I planted Oasis in 2001 and have been so blessed seeing all that God has done.  We are thankful and believe that the best is yet to come.

Dawn Claudio

Worship & Women's Pastor

I was raised in Martinsville, VA in a Christian home with two loving parents and three older siblings. I experienced God at a very young age and accepted Jesus then. I was involved in music from a young age, as well. Singing and playing the piano to this day are things I love to do.   I even had the opportunity to preach my first sermon at the age of 10 in two different churches.  I began in full-time ministry while still in high school. Ministry training was developed in Cleveland, TN. at New Life Bible College & the New Life Drama Company. (A ministry I traveled with full time for 3 years.) After marrying the love of my life in 1989, we traveled extensively across the United States doing ministry through music, drama and teaching the Bible in local churches. It was during this time that I had my two sons, Billy & Nick.

After 10 years on the road, we settled in Greenville, SC where my pastoral leadership was developed.   In 2001, my husband and I felt the call to plant OCC, where I currently oversee the Worship Ministry, Women’s Ministry, and Freedom Ministry. I feel so blessed to serve with so many great people in our leadership and church body.

I also enjoy the opportunities where I get to travel to speak at other churches and conferences. I also love to spend time with my two sons, daughter in law, Tawny and my granddaughter, Presley.

Andrew Milich

Executive Pastor

I grew up in Chicago as a devout catholic and became a believer in high school while attending Willow Creek Community Church.  Having been in ministry for over 20 years in many different positions, I can truly say God has called me to this.  I have a B.A. in Liberal Arts  with an emphasis on Psychology, and Ministry from Trinity International University in Deerfield, Illinois. After graduation I attended Trinity Evangelical Divinity Seminary while pursuing an M.A. in Christian Education. While at school I met my wife Elisabeth who is incredibly beautiful.  It was easy for her to convince me to move to Arizona where she is from. After years of full-time ministry I decided to enter the marketplace and became the Vice President of Operations for a technology company headquartered in Arizona. About 7 years ago, I felt the call back into full-time ministry. I have been an elder and volunteer at Oasis for over 11 years.  We love this place.  I have been married for over 22 years and have 3 kids and 1 son-in-law.  Macie 22 & Brandon,  Noah 19, and Kate 14.  In my free-time I am an avid hunter and enjoy fishing.  I played baseball in college and have a deep love for the Chicago Cubs. If you want to hang out for lunch nothing beats a good hot dog or Vienna beef.

Marquavious Walker

First Impressions/Young Adult Pastor

I was born and raised in Atlanta, Georgia. It wasn't until bible college that I truly gave my heart to the Lord in 2012. I attended Valor Christian College for three years and went on to pursue my bachelor's in Business Management at Ohio Christian University. Most of my career has been spent in the corporate world. In my free time, I dedicated it all to serving in God's house in various capacities on different ministry teams. While completing my second year in a Church Planting Residency, I met the most beautiful woman in the world who happens to be my wife, Hope. We got married in 2019, relocated to Arizona, and had our son, Jude in 2021. I am honored to have the opportunity to lead our assimilation process and our volunteer core (The CREW). I also have the amazing honor of shepherding our young adults, which I believe is the future of Oasis. My motto is simple, "Make much of Jesus on the earth, until all have heard"!

Brian Neary

Student Ministries & Group Life Pastor

I was raised in a Catholic home but did not truly accept Jesus as my Lord and Savior until my mid-30’s.   In my early 20’s, I achieved tremendous levels of success by the time I was 25, but still felt an enormous amount of emptiness and lack of direction.  That all changed when I asked God to give me purpose, so He decided to bless me with my wife, Andrea.  We got married and started raising our family back in Minnesota.  We were missing just 1 major thing, God.  After we moved to Arizona, our kids were the ones that actually led me back to church and ultimately, Jesus!  After many years of wandering, I ironically found my way to the desert to reunite with God.  For the last 9 years, Jesus has been my inspiration on how to live with peace, joy and true happiness!  I’m thankful every day for my relationship with Him and look forward to spending the rest of my life getting to know Him better each day.

Andrea Neary

Children's Director

I was born and raised in Minnesota. I grew up appreciating the small towns, lakes, and an amazing fall season. To my surprise,   God moved my family and I to Phoenix in 2010 where we found Oasis and more importantly the Lord.   My kids were the first to attend and become involved at church.  Eventually, it was their faithfulness that helped lead me to the Lord.  I am a direct result of how God can use children's ministry an a life transforming way. I am thankful God has given me a passion for reaching and teaching the future leaders of tomorrow for the sake of Jesus.  

Mary Halter

Creative Director

I was born and raised in a small town in South Jersey. I can honestly say, there isn't a moment in my life where I don't remember having a relationship with the Lord. From a young age, I loved going to church and would volunteer whenever possible. In 2015, a graduated with a BFA in Film Production/Editing. I committed to the Lord that my talents were His to do whatever He wanted. In 2017, I joined the ministry, New Life Drama Company, where my gifting and passion for the Lord grew. Over these past years the Lord has radically transformed my life! I am so honored use my talents as the Creative Director here at Oasis. Everything we do has impact, and I am blessed to be a part of sowing seeds for the Kingdom through the arts!

Maria Cornell

Accounting

I was raised in Chicago with roots in the Catholic church, but also was raised with the influence of the occult and spiritualism. We moved to Arizona and I was saved at the only Billy Graham Crusade that came to Phoenix. College and Careers took paths of International Marketing and owning several businesses. In college, I majored in Business and minored in Accounting. I was on the Board of Directors of Athletes International Ministry, working with athletes, golf tournaments, and benefits, all helping youth at risk. As well as numerous other organizations. I joined Oasis at the second service 17 years ago, and there is not much I did not do during all these years.  Family is special to me. I met Jack in college, but married 14 years later. We just celebrated our 25th anniversary. We have a daughter Nika who is married.  Life has not been easy thus my passion to help people see life from an eternal perspective and trust the Holy Spirit to be there.  He is the One true constant to get them through anything. I love serving ’til the King returns.
