Rich Sellhorst
Founder
2006
SELLHORST has been delivering custom home solutions since 2006—but our story began much earlier. In 1982, Rich Sellhorst, father of current president Steve Sellhorst, began his career in the low-voltage industry. That early foundation set the stage for what would become a trusted, family-owned business built on generations of expertise and dedication.
When Rich officially founded SELLHORST in 2006, his focus was clear: to provide dependable home security solutions for local families. With a strong work ethic and a deep commitment to protecting what matters most, he grew the business from the ground up—earning a reputation for quality, trust, and personal service.
As technology advanced, so did the SELLHORST vision gradually expanding beyond home security to offer full-service solutions in audio/video, smart-home automation, and more. Yet through every phase of growth, at SELLHORST we remain grounded in the values that started it all: integrity, craftsmanship, and genuine care for the client.
Today, that legacy is proudly carried forward by his son Steve and the entire SELLHORST team. With family at its core and innovation as our guide, SELLHORST continues to evolve—building smart, connected homes for the future while staying true to the values that shaped our past.
Steve Sellhorst
Owner
2006
As the owner of SELLHORST since 2006, Steve continues the legacy of excellence that began with his father, Rich. With a commitment to preserving the family-oriented culture at SELLHORST, Steve blends decades of expertise with a fresh vision for smart-home innovation.
Driven by a passion for cutting-edge technology, he collaborates directly with each client to craft personalized systems that align with their lifestyle. From security to automation, his goal is to simplify the home-building process—making it both seamless and enjoyable.
Under Steve’s leadership, SELLHORST remains rooted in quality, reliability, and innovation—ensuring every client feels safe, connected, and truly at home.
