Our Team
John Dienner
Position: Partner/CEO
About me:
I serve as Co-Owner and CEO at Site Prep, overseeing daily operations and helping our team deliver high-quality results for every customer. My brother Mike and I started the company in 2014, and it has been an exciting journey of growth and relationship-building ever since.
What I enjoy most about my role is working alongside a dedicated team and seeing our customers happy and excited about the work we do for them. Being born and raised on a dairy farm in Lancaster County, PA taught me the value of hard work and the importance of community—lessons that continue to shape the way I lead today.
Outside of work, my greatest joy is spending time with my wife and our five children. Whether we’re traveling on mission trips, experiencing new cultures, or just gathering in the backyard, those moments are what I treasure most. One of our favorite family traditions is sitting around the campfire and enjoying simple finger food together. Along with family time, I enjoy cycling, hunting, grilling, and experimenting with new cooking techniques.
One of my favorite mottos is simple: “We’ll figure it out.” I’m passionate about community and love creating spaces where people can connect, encourage each other, and grow in their God-given gifts.

Family is everything to me. I love spending time with my wife and children, whether that’s playing a ballgame together or sharing stories around the dinner table. I also enjoy playing sports like softball, pickleball, and basketball, as well as being outdoors hunting or raising horses. Some of my favorite moments are taking the horses out for a ride, heading to the mountains, or relaxing at the beach while taking in God’s beautiful creation.
Two of my favorite passages are from Matthew 7: “Every good tree bears good fruit… A good tree cannot produce bad fruit.” (verses 17–18) and “The wise man built his house on the rock, but the foolish man built his house on the sand.” (verses 24–27).

Two of my favorite scriptures are: “Do not let kindness and truth leave you; Bind them around your neck, write them on the tablet of your heart” (Proverbs 3:3), and “Where no oxen are, the manger is clean, but much revenue comes by the strength of the ox” (Proverbs 14:4). These verses remind me to speak the truth in love and that when life isn’t perfectly neat and clean, it usually means real progress is being made.
My motto: “Bring kindness, truth, and a little bit of grit into everything you do.”
