The OneLife Team


Our Team


Peter Sullivan

Founder & CEO

My wife Debbie and I have five children. We have lived most of our adult lives in Greenville, SC where I spent 27 years working for and eventually owning Genesis Marketing. During my time at Genesis, I had the opportunity to join my kids on several mission trips. This ignited a growing desire to influence the next-generation to live for something bigger than themselves. OneLife grew out of that desire and I love being a part of what God is doing in the lives of students

Josh Beers


I have spent my entire life since college investing into the next generation in both high school and college settings. My passion for OneLife is to see life on life transformation take place that leads students to make a lifelong impact on others for the glory of God. My wife, Anna, has faithfully served alongside me the past 26 years, and we are blessed with 4 children. I love students, but in my free time, I enjoy coaching my kids’ club soccer teams and an occasional round of golf.

Charity Smith

Enrollment Director

I grew up in Northeastern Pennsylvania. Ever since I can remember I loved being around people. God has continued to ignite my passion to serve people through working in admissions for the past decade; first as a college student worker, then as a full-time admissions counselor and now as a director. I am eager to connect with students and their families to encourage them in their walk with Jesus and see if God could be leading them to OneLife! I love everything about the OneLife program specifically our mission and values! I really can’t think of a better way for young adults to spend 9 months as they enter into adulthood!

Joel Hughes

VP of Operations

My name is Joel Hughes and I was homeschooled in South Jersey with my three brothers. I enjoy playing soccer, golf, guitar, and taking road trips. I now live in Lancaster with my wife Janelle and bunny Johnny (Piper). I am a OneLife alum and I am passionate about the work of OneLife since I have experienced it myself! OneLife changed my life and I’m excited about helping build a OneLife that will disciple students and change lives for years to come!

Dawson Loh

I was born and raised in beautiful Lancaster, PA. I like to stay active and enjoy playing racquetball with my dad whenever we get the chance. I am a OneLife and OLX alum, and I love the heart of this program and the people that make it happen. I am passionate about my work with OneLife because it enables others to positively impact the hearts and minds of students for generations.

Derek Melleby

Site Director & VP of Academics

I have lived in Mount Joy, PA my entire life. I married my high school sweetheart Heidi, also a life-long Mount Joy native, and together we have three sons. I love basketball, reading, writing, but not arithmetic. My passion for OneLife stems from my life-long passion to see students learn and grow as disciples of Jesus. (Invite Derek to speak to your students.)

Jessica Egan

Assistant Site Director

I was born in Wisconsin but currently claim Pennsylvania as my home. You can usually find me either laughing, reading a book, or drinking coffee/tea. As a OL alum and now staff, I have absolutely loved walking alongside students as God does a transformational work through each one of them. It is truly a blessing to love going to work each day knowing it’s not just a job, but an opportunity to make an impact in young people’s lives as they ask hard questions and learn to live in intentional community.

Myranda Shymansky

Resident Leader

My name is Myranda Shymansky and I am from Southern Maryland. I moved to Western Pennsylvania to attend Geneva College for my undergrad and grad degree. As I have seen in my own life, freshman year of college is one of the most pivotal for a lot of people, and I feel so blessed to be able to walk alongside students of this age as they discern their calling and grow in their character. The mentors in my life who decided to disciple me and point me to Christ made a huge impact on my life, and I hope to be able to do the same for these amazing OneLifers!

Logan Stoner

Resident Leader

I was born and raised in Chambersburg, PA where I graduated from Chambersburg Area Senior High School. Upon graduating high school, I attended OneLife Institute as a student at Three Springs Ministries and then continued and finished my undergrad at Lancaster Bible College. I could not be more ecstatic to pour back into the ministry that has quite literally transformed my life and join Jesus in the redemptive work He is accomplishing in the lives of so many students through this program.

Matt Hunter

Site Director

I grew up on a horse farm in upstate New York and I’ve been a Christian for as long as I can remember; although there have been (and continue to be) profound moments of God’s transforming work in my life. I majored in Christian ministries in college and worked in Urban and Suburban Youth and College Ministry for 5 years before I started my PhD in Religious Studies – completed in 2010.

Gavin Potter

Assistant Site Director

I am from Central, South Carolina, graduated from Southern Wesleyan University (SWU) in 2015 with a degree in religion and started working at OneLife in the fall of 2015. I love my job because I am passionate about knowing and experiencing life with Jesus while inviting others to do the same.

Anna Campagna

Resident Leader

Hi, y’all! My name is Ana Campagna (like Lasagna)! I am originally from GA but coming from the sunny state of Florida where I earned myBachelors’s degree in Communications at Southeastern University and worked at a small business home staging company for 1 year as a marketing coordinator. Some of my passions include: trying new healthy foods, nature walks, listening to podcasts, running, walking the farmers market with friends, and game nights with family. I am so excited to be a part of OneLife this year as a Resident Leader and I am so expectant to see how God is going to move in and through the students!

Lydia Dice

Resident Leader

My name is Lydia Dice, and I am from Ocean City, New Jersey. I attended OneLife as a student from 2016-2017, and God used it in my life to grow me in incredible ways, show me more of what biblical community looked like, and reveal more of His love for me. I work at OneLife to pour out the love that has been given to me from the Lord and His people. I love being part of an organization that is rooted in the gospel and seeks to preach it and live it out every day in every area of life.

Collin Kauffman

Resident Leader

Hey! My name is Collin Kauffman and I’m from Lancaster, Pennsylvania. I graduated from Kutztown University in May 2021 with a Criminal Justice degree.

Timothy Cote

Site Director

I am a native of Lancaster, PA, and a graduate of Lancaster Mennonite High School, Millersville University, and Evangelical Seminary. God has blessed me with a precious family, including my wife, Christa, and our four rambunctious children. And I am grateful to serve with OneLife, because I see the people here doing things Jesus did constantly: loving people where they are and calling them to greater purpose, meaning, significance, and hope.

Julie Martin

Assistant Site Director

After spending the last 3 years of high school in Liberty, PA, I participated in a Christian Gap-Year Program run by Three Springs Ministries called True North. From there I attended Cairn University and eventually went on to teach 3rd graders at an elementary school in Southeast Asia. I have a heart for mentoring students of all ages, and I am so excited to work with OneLife students! True North had such a huge impact on my life and I am so grateful to return to a place where I can invest deeply in the lives of students!

Joel Davis

Resident Leader

I graduated with a degree in Youth Ministry from Messiah College in 2013. Since then, I have been pursuing my passion to develop student leaders in various ministries around the States. I am a proud uncle to 5 nieces and nephews, I enjoy creating art, and I once lived a year without shoes. I’m excited about OneLife because I get to use fun as a tool that leads to depth in relationships and growth in the knowledge of Jesus’ plan for the world at large, and specifically the lives of each student.

Community & Discipleship

God designed us to grow in character and calling in deep community. The people you surround yourself with is one of the most important things you will ever do.
