WILTON – Samuel Schwanke is an unusual kind of businessman.

He’s 18 and a college student in Pensacola, Fla., working on a degree in business management, and he has owned his driveway sealing business for three years.

But while working to pay for his education, 20 percent of what he earns through Schwanke Sealing is donated to a faith-based addictions program in Manchester.

“I have been sealing driveways for three years,” he said in an email. “In the summer of 2014, my friend asked me to help him seal his driveway by hand. After he showed me, I did my neighbor’s, and then continued from there.”

Schwanke saved his money for two summers and bought a commercial-grade machine in summer 2016.

“I did over 60 driveways and two parking lots in the summer of 2016,” he said, “and my goal for 2017 is 200 driveways and 10 parking lots.”

After graduating, he said, “I might expand it into a paving business, as well. It just depends on where God leads me in my life.”

Schwanke said he chose driveway sealing because “it preserves the life of your driveway, just like you would stain your deck to protect the wood from rotting out. You want to do the same to your driveway so you don’t have the cost of repaving.”

He noted, “Our mission is ‘Save, Seal, Serve.’ Save money by sealing driveways and parking lots. Not only am I saving the money earned, but giving 20 percent earned to serve our community.”

His support goes to Reformers Unanimous, a faith-based addictions program in Manchester.

“They provide services to help those addicted to any addiction to be set free and start serving Christ,” Schwanke said.

Schwanke grew up on Abbott Hill and graduated from Dublin Christian Academy.

“I enjoyed growing up in Wilton,” he said, “spending summers at Goss Park, visiting the Wilton House of Pizza and Nelson’s Candies.”

Schwanke said he was thankful for his family.

“My family taught me to have a good work ethic and to serve and help others,” he said.

He also thanked his coaches in baseball, basketball and soccer “for all the time they invested in me.”

He credits his family for “teaching me at a young age the consequences of wrong choices so I don’t wind up in addiction. When I’m home, I work in the church on Sundays and work with the kids of those who are addicted. It amazes me how much joy I receive from helping and working with these kids. That’s why Schwanke Sealing is all about giving back to this ministry.”

He added, “As I approach every customer and future customer, I want to keep our mission in mind.”

His goal is to lower the addiction crisis in New Hampshire.
