OUR TEAM

OneLife Corporate 

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.

  Derek Melleby: Executive Director  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.)

  Zac Northern: LBC Site Director  I am originally from Pittsburgh, PA and have the blessing of being the husband to Jessica and father to our daughters Naomi and Lucia. After graduating from Geneva College with a BS in Psychology and an MA in Higher Education, I was a campus minister with the CCO (Coalition for Christian Outreach) working at Waynesburg University and Grove City College. I love my job because I get to lead students in the wise way of Jesus and prepare them to follow Him in every area of life as we taste and see that He is truly good.
