Why the Name JNJ Matters
The name JNJ Plumbing was chosen in honor of someone who has had a lasting impact on our lives; someone whose strength, resilience, courage, humility, and unwavering spirit helped shape the foundation of what we’re building today.
He believed in us when it mattered most. He saw something in us before we fully saw it in ourselves, gave us opportunities that changed the course of our lives, and showed us what it means to lead with heart, character, and quiet strength.
The lessons we learned through those experiences continue to guide us today. They shaped the kind of company we wanted to build. Genuine care for others.
We believe that adversity reveals character. The challenges we’ve faced have reinforced the importance of perseverance, humility, integrity, and treating others with kindness and respect.
Those values are at the heart of everything we do at JNJ Plumbing. We are committed to providing honest service, fair pricing, quality workmanship, and a customer experience built on trust. Every day, we strive to be the kind of company people feel confident calling when they need help most.
Built on Second Chances
Both of us have walked our own recovery journeys, and those experience have deeply shaped who we are, both personally and professionally. As co-owners of JNJ Plumbing, Bo Schmidt and Dana Gissal have built their business on the values of accountability, consistency, gratitude, humility, and perseverance. Our journeys taught us how to keep showing up, how to rebuild, and how to create something better than what came before. Those lessons remain at the heart of JNJ Plumbing and our commitment to providing honest, dependable service to our local communities.
