Staff
John Oostdyk
Executive Director
Hard work and serving others are no stranger to John, growing up in West Milford, NJ. His father instilled a passion for meeting needs in the community at a young age, waking him up every Saturday morning to do community service projects since he was 11 years old. After 6 years of flipping houses, 12 years serving as a youth pastor at Cornerstone Christian Church, and graduating college with an organizational management degree, John transitioned to a part-time pastoral role in order to step into a full-time position as Executive Director of Servant’s Heart Ministry. Since then, John’s been living out his passion for working with his hands, loving people, and seeing lives changed through the gospel.
On his off hours you can find him ATVing or hiking with his wife, Tara, and four boys, Colby, Shane, Hunter, and Chase, or working on one of his many projects in his basement workshop.
Christina Mendez
Director of Operations & Marketing
Christina initially started volunteering on Saturdays with Servant’s Heart to spend more time with her dad, learn some new hands-on skills, and serve people in a tangible way. She never expected in 2018 she would be leaving her job as a designer in the fashion industry to work full time for a construction organization, but her passion for serving the community, empowering people, and newfound love for trades work made leaving her job an easy decision.
When Christina’s not running social media, organizing an event, or tiling a wall, she’s eating food with friends, watching Parks and Recreation, and imagining renovating her own fixer upper one day.
Darren Ojeda
Director of Projects & Pastoral Care
Darren has worked bi-vocationally for the last 15 years, pastoring and working in the trades show industry. As he began volunteering consistently with Servant Heart over 2020, it became clear his gifts for discipleship, serving, and project management would be an incredible asset to our staff. Now Darren is serving full-time, assisting John with development and project management, while dedicating himself to growing Servant’s Heart’s ability to evangelize and build up more servants.
When he’s not making cut lists and striking up faith conversation with volunteers, you can find Darren biking with his son, Jesse, or spending time with his wife, Caryn.
David Justnes
Construction Manager
After one year at Northeastern Bible College, David felt the Lord leading him to work in construction full-time. Early in his career, David owned his own construction company and continued the next 30 years working for companies in commercial, industrial and railroad construction. David is passionate about teaching construction to those who are eager to learn and employing the spirit of service. When volunteering as an instructor for our Workmanship Program, the Lord tugged David’s heart to join the Servant’s Heart team full-time. He believes that the Lord has prepared him through his diverse work experiences to carry out his new role as Construction Manager with excellence.
When David isn’t sharing his wealth of knowledge about construction, you can find him hunting, fishing, spending time with his family and telling dad jokes.
Tim Braunlin
Project Manager
Tim found Servant’s Heart while working in maintenance at a camp in Ulster Park, NY. Wondering who else was ordering lumber in the area when he saw a truck drive by, Tim was led next door where the Servant’s Heart crew was working on a project. It didn’t take long after bumping into the team again on a project they were doing for one of his friends that Tim signed up to volunteer with Servant’s Heart.
In October 2016, Tim joined our team full time, bringing his diverse background and set of skills with him. Years of working in facilities maintenance at a church, camp, and missions organization has brought him unique problem solving experience, which he uses daily on our projects. Tim’s favorite jobs involve applying his diverse experience to solve simple problems that have great impact on a homeowner.
Stan Hankinson
Project Manager
After 40 years working as a plumber and eight years volunteering with us, Stan decided to join Servant’s Heart’s staff full time in 2019. He’s an incredible asset to our team with his diverse experience in construction, including roofing, siding, cabinetry, and mechanics, as well as his awesome heart for serving people. If you get the opportunity to work alongside Stan on a Saturday, you will be blessed by his mentorship, passion for using his gifts to serve others, and maybe even a little singing.
In his freetime, Stan enjoys golfing, fishing, watching baseball, eating perogies, and spending time with his four sons and wife of 30 years, LaDonna.

Nate Dorka
Development Coordinator
After graduating from Ramapo College with a degree in business management, Nate has been serving in church ministry for the last 10+ years: building out a church youth program, serving as campus pastor for a new campus, and finishing as pastor of community engagement, which lies closest to his gifts and passions. It was in that role, connecting the church to local non-profits and helping people serve with their gifts, that Nate first got connect with Servant’s Heart. Now Nate will be using his gifts for people and passion for serving, to help our team connect with new groups of people, and help individuals get plugged into serving at Servant’s Heart.
When he’s not networking with new churches or listening to volunteers share their story, you can find Nate enjoying craft coffee with his wife Kait, or building a playroom for his 4 kids.
Daina Ommundsen
Creative Designer
Daina never expected to find herself working in ministry, because although she’s always desired to use her creative passions to serve others, she didn’t know how. Now that she’s landed a spot on Servant’s Heart’s staff, she’s excited to use her 4 years work experience in design, marketing, and communication to help us grow. In addition, her recent interest in interior design makes Servant’s Heart the perfect place to learn about the walls behind the design.
When she’s not designing creative content for Servant’s Heart, you can find Daina doing outdoor activities with friends, thrifting for unique finds, or curled up with her dog.
Andy Tyler
Program Coordinator
Andy spent the majority of his career in sales, 15 of those years working for the wholesale division of Wayne Tile. Although he loved his job and the company, he felt God had another plan, which lead him to launch an agriculture start-up with a partner in Haiti. Unfortunately, Covid derailed the launch, leading to an unexpected year of homeschooling, leading youth, and working at a local farm. Little did he know, his previous boss at Wayne tile would connect him to what he’s doing now at SHM: spearheading Workmanship’s tile course. We believe the Lord’s timing was perfect for Andy to come on board and help get this new program running.
In Andy’s spare time he loves mountain biking and fishing with his kids and getting out on the water in any way possible.
Yvonne Zuidema
Grant Coordinator
Yvonne has 30 years of experience in the nonprofit sector, including 20 years as an executive director of a nonprofit in Paterson. She retired in 2022 and is now consulting to nonprofits in New Jersey having a focus on creating programs that address poverty and specializing in program development, program evaluation and grant writing.
Yvonne has been faithfully volunteering by serving meals to our Workmanship students since September of 2021. We are so excited to have her on our staff, bringing her expertise in grant writing.
In Yvonne’s spare time she loves hiking, kayaking, enjoying the outdoors and spending time with her 3 children.
FAVORITE TOOL
It’s a 3-way tie between a laser cutter, 3D printer and a router. The possibilities of what I can make with these are endless!
Jessica Sledge
Operations Coordinator
Jessica, “J”, graduated with a degree in Industrial Design in June 2022 from CUNY LaGuardia and studied 3 years of architecture. This led her to her 13 years working as an after-school Art & Design Instructor with experience in administrative work. Although she enjoyed learning the technical part of design, she enjoys being hands-on, which led her to enroll in our Workmanship Program’s CPM course. After graduating from both CPM and our Fine Woodworking course, Servant’s Heart asked J to join the Operations team to help with our Workmanship Program’s needs behind the scenes.
In J’s spare time, you can find her being creative with art, modelmaking, working on furniture designs, sewing, and cooking. She also loves cartoons, video games and spending lots of time with her friends, family, and her cat, Jax.
