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

Administrative Coordinator


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.

Michelle Rienstra

Administrative Assistant


Michelle first caught Servant’s Heart’s vision for serving the community when our team stepped in to do a project for a friend of hers, who was going through a devastating situation. Five years later, after graduating Nyack College with a bachelor’s degree in social work and working five years in the school system, Michelle joined our full-time staff as an administrative assistant. Although she never expected to work for a construction organization, she’s wanted to serve in ministry since high school. Now she’s living out her passion for supporting people emotionally and spiritually to help them find freedom, as she helps our team stay organized, respond efficiently, and communicate well.

When she’s not in the office, you can find Michelle hiking with friends, drinking coffee, and watching Brooklyn Nine-Nine.

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.

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.

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.

Nathan Breckenridge

Project Assistant


In 2018, Nate started volunteering with us on Saturdays, but soon after left his job at a hardwood floor company to intern with Servant’s Heart full time. Nate was drawn to serve on our team by his desire to pursue a career in construction, but stayed for the comradery and empowering atmosphere. Since August 2018, he has been a huge help on our sites, working alongside our project managers and jobsite leaders.

On a project site, you’ll find Nate most in his element when he’s framing, and in his freetime you’ll find him hiking with friends.
