Osterville baptist church Staff


Senior Pastor   Rob Wheeler

I am committed to Christ’s gospel (which I see as the central point of the Scriptures), Christ’s church and training men and women to be passionate followers of Christ, trusting Him with every area of their life. In short, I am committed to Jesus!

I am married to my lovely wife Katie, since 2006, and we have three children—Lexi, Zac and Isaac. Our ambition as a family is to use our spiritual gifts, passions, and natural abilities to participate in advancing Christ’s kingdom on this Earth. We are glad to do this work at Osterville Baptist Church.

If you are looking for a church home, look no further! Osterville Baptist truly is a place where people—babies to seniors—can find the Word preached, nurturing discipleship, a commitment to prayer, and, one of our big words, family. We are a bunch of changed lives who are being used by God to change lives in turn, all by the power of Jesus!


Pastor of Worship James 'Kimo' Baker 

I am so passionate about leading worship because it gives me an opportunity to share my love for our Savior Jesus Christ and help usher His children to His feet through: scripture, prayer, music, speech and giving. I believe that Worship is an expression of adoration of and to God. Our main priority in worship is to magnify the Lord through clear and specific expressions while exploring God’s greatness.

I was married in 2001 to my beautiful wife, and together we have two amazing children. I am a graduate of Trinity College of the Bible with a B.A. in Pastoral Study and a graduate of Trinity Seminary of the Bible with an M.A. in Pastoral Study. 

I look forward each Sunday to Worshiping the King of Kings with my Church Family and anticipate an outstanding time of Spiritual Growth in the coming years.


Pastor to Students and Families
James Trevillian

Student ministry changed the course of my life forever. God used student ministry to introduce me to a life of following Him. I have the great joy of continuing that tradition at Osterville Baptist Church. It is my desire to see students and their families place their faith and trust in Christ, grow deeper in their walk with Him, and experience the joy of ministering to others.

My wife, Miriam, was baptized here at OBC as a teenager and was discipled in the student ministry. We attended college together and were married in 2004, also here at OBC. In 2019, God brought us back here to the Cape after 15 years of serving churches in California and New Mexico. We have been blessed with two wonderful children, Lyndi and Nate.

If you are a student or parent who has found their way to this page, let me be one of the first to welcome you to Osterville Baptist Church! Know that this is a church family where you will be loved, encouraged, prayed for and discipled. Don’t hesitate to contact me if there is anything I can do to serve you and your family.


Director to Children and Families
Jessica 'Jecca' Mahler

I'm a passionate follower of Christ with a deep hope in His faithfulness to me and to His Church. Looking back on the legacy of gospel instruction and modeling of Christian faith surrounding me growing up, I am endlessly thankful for this gift and how it has shaped my identity and directed my life. It is my joy to use all God has gifted me with to inspire and equip others in family ministry.

Scripture commands we instruct children in the way they should go, and as OBC's motto says about "Changed lives, changing lives," I believe we are all called to be teachers - investing in the formation of faith from generation to generation as we are moved by our own transformation. 

As the mother of two precious girls, daily feeling the weight of this endeavor, I am thankful for a church that is committed to empowering families. Praise God that He always provides for that which He asks of us!  


Office Administrator Erica Corbiere

God has not only encouraged and guided me in discovering my spiritual gifting of administration and helps, but has provided a perfect outlet to use those gifts here at OBC. Though I'm new to the receptionist position, I am familiar with the church. I've been attending OBC since I was born, was dedicated here as an infant and baptized in front of my OBC family at the age of 12.

After five years away at college studying Spanish and Linguistics followed by a year of teaching English in Laos, Southeast Asia, I returned in 2017 to OBC. I love serving alongside this fantastic staff. I'm here for all your phone calls, emails, and office visits with any questions or assistance you may need.  


Treasurer Amanda Kleoppel

My joy and passion in life is helping from behind the scenes. I enjoy supporting and encouraging my team to succeed in their endeavors especially when it is furthering the kingdom!  During this season of life I am thankful to be currently working at home raising our three children. My degree in teaching mathematics has helped me in various capacities, and right now it is helping me as I help guide the church through its daily tasks of paying bills and keeping the staff stay on budget so that we may remain faithful to what the Lord has blessed us with.

Harry Fletcher

Missionary at Large  Harry Fletcher

It has been a great privilege to serve the Lord for 51 years along with my wife Muriel.  Throughout those years, we have been involved with Good News Jail & Prison Ministry, including serving 25 years in the pastorate and 7 years in academia.  The Lord has given us two daughters, both married with three sons each.

We fell in love with the people at OBC when I served as Interim Preaching Pastor in 2015.  We love the faithful exposition of the Holy Scriptures by Pastor Rob each Sunday and have a heart for evangelism, discipleship, and pastoral care.  OBC affords opportunities for people from all backgrounds and ages to grow to Christian maturity.  Here, you will be fed the Bread of God’s Holy Word that will lead you to the Bread of Life, our Lord Jesus Christ. 


Worship Assistant Josiah Estabrooks

My family moved to Cape Cod from Canada in 1999, and I have been part of the OBC worship team since 2009. Music is my passion and worshiping corporately has opened my eyes to a desire to lead and participate in our worship every week. I'm excited to learn from my position as Worship Intern, and learn from the people around me to grow and develop as both a worship team member and as a Christian. I hope to be a resource to the members of our church, and answer any questions that you have for me.
