Midwest Roots. Manufacturer Results.
GSO Sales & Marketing is a group of seasoned industry professionals with extensive market experience, along with extensive product knowledge, industry relationships, and a robust, well-balanced work ethic.
Built on Relationships, Driven by Results
GSO Sales & Marketing was founded on a simple belief: manufacturers deserve sales representation that actually knows their customers. Too many companies were sending products into the midwest with no local presence, no relationships, and no real accountability.
We built GSO to fill that gap. Starting with a handful of manufacturer lines and a commitment to showing up — in person, consistently, with expertise — we grew into one of the most respected independent rep firms in the region.
Today we represent manufacturers across a 10-state territory, covering industrial, commercial, and specialty markets with the same hands-on approach that defined us from day one.
Two decades of building the relationships, market knowledge, and manufacturer trust that define a great rep firm.
The GSO Difference
Local Knowledge
We live and work in the territory we serve. Our reps know the buyers, the distributors, and the competitive landscape in every market we cover.
Manufacturer Partnership
We don't just carry your line — we invest in understanding your products, your goals, and your customers so we can represent you with authority.
Accountability
Regular reporting, transparent communication, and measurable results. You always know what we're doing and what it's producing.
Long-Term Thinking
We build relationships that last. Our average manufacturer partnership is over seven years — because we deliver results that keep everyone coming back.
