Amos Groenendyk

teaching pastor (lead)


Amos and Alison share almost all their passions and hobbies: we love talking about “church,” watching football, hiking and doing home renovation projects together. They have a beautiful, fiery daughter, Aisla Josephine. Life, marriage and ministry has never been the same since her birth in 2019! 


Amos graduated from Calvin University and then Calvin Seminary with a semester abroad at Jerusalem University College and internships in Uganda, Montana, and Ohio He has served as a kids director, youth pastor and in 2011 God called he and Alison to be the planting pastors of Revive Vineyard Church in Grand Rapids, MI. In 2016 we moved to Pennsylvania to become the “second generation” pastors at the Vineyard in Chester Springs after Bob and Marilyn Palumbo’s retirement.  


Amos values spiritual depth, emotional health, and an engaged mind. He would love to connect with you over beer, coffee or a bowl of ice cream. He is a student of the Bible and his favorite authors/thinkers are NT Wright, John Mark Comer, St Augustine, Brene Brown and JRR Tolkien. He frequently recommends the ESV Study Bible as his favorite resource.

Alison Groenendyk

pastor of spiritual formation (lead)


Alison loves learning about communication, relationships, psychology, and the human body, and she found a career in medical speech pathology to be the perfect blend of these passions! Alison worked as a brain injury specialist for 8 years across many hospital and rehab settings, and was a clinical instructor at her alma mater, the University of Northern Iowa!


Alison has been a part of the Vineyard movement since 2004, when she began searching for a church that valued equally the Bible and God’s Spirit! Her first time in a Vineyard church, she knew she was “home”. She loves the authenticity and radical welcome of the Vineyard, and that we get to live life together in response to simply being loved perfectly by Jesus! Alison has served in many leadership roles in adult groups, youth ministry, worship, outreach, and young adult ministry. Amos and Alison planted and pastored a Vineyard Church in Grand Rapids, Michigan soon after they were married in 2010.


A trained spiritual director through Sustainable Faith, Alison is at her best when helping individuals and small groups experience the healing and wholeness Jesus offers. Her pastoral roles include overseeing Life Group leadership, Sunday Serve Teams, Care and Financial Assistance Systems and Events planning. She also helps to set the strategic vision of the church and staff, and to grow our culture of spiritual formation and emotional health!  


Alison loves to geek out about neuroscience and new medical procedures, and still reads medical journals for fun! ;) In her free time, you’ll find her painting landscapes, listening to good music-all kinds, hiking mountains, cheering (loudly) for the Green Bay Packers, perfecting her homemade coffee syrups and lattes, and cuddling her sweet Ragdoll cats, Mika and Ruki!

Emily Nefos

pastor of vineyardkids

Emily grew up in Ohio, but moved to Pennsylvania as a teenager. After attending Eastern University, she was a missionary for a few years in the Congo and eventually returned to Pennsylvania where she married her longtime friend, Frank Nefos. Together, they visited VCC and never looked further! After teaching for 5 years, Emily and Frank had Zachary and two years later, Maggie. 


Emily has served at the Vineyard for nine years in children’s ministry, outreach, homegroup leading, and other areas. She was thrilled to come on board to handle the finances four years ago and even more thrilled to be asked to come on as an assistant pastor this year.


Emily loves the outdoors, swimming, spending time with family, reading, traveling, learning, praying for people and just talking, in general!

Tyler Stellmack

Pastor of Youth and Worship

Tyler & Courtney.png

Tyler was born and raised in Syracuse, NY where he was invited to come to the Vineyard as a youth and he loved it! The sense of "home" at the Vineyard along with the kindness and realness of the people really felt right to him.  

As a youth growing up in the Vineyard, Tyler found a love for worshipping God through music and creativity along with community. Tyler found his way through youth group at the Vineyard and started serving at the Syracuse Vineyard in ways like tech/sound teams, worship teams and youth leadership. It was in youth group at the church that Tyler met Courtney, now his wife!


As Tyler went to college at SUNY Oswego in Syracuse, studying Graphic Design and Audio Design and Production, it became clear that while he loved all different types of creativity in art and music, Tyler's true passion was for people and God was calling him to work in ministry. Tyler felt a strong love for worship, design and for youth, especially since the reason he is here today is for the people that invested in him and the relationship with God he built as a teenager and young adult. 

During college, Tyler underwent internships at the Vineyard for his 4 years in school to follow God's call to learn more about the church and serve in new areas. After graduation in 2018, Tyler and Courtney (and their cat Benji!) moved to Pennsylvania to pursue a call that God has to come and be a part of His plans in PA! 

Tyler loves football and baseball (Go Phillies!) and pretty much anything that has to do with people getting together and just enjoying one another's company. He also loves the shows Mad Men, Peeky Blinders, Any cooking shows and pretty much anything that has to do with Marvel, Star Wars and/or Lord of the Rings. Tyler also loves trying new food, hiking and biking outdoors!
