Building on her experience in purchasing, sales, and international sourcing, Susan Ondovic founded S.O. Sales in 1987. She recognized early that carefully selected manufacturing partners gave OEMs access to specialized capabilities, competitive costs, and reliable supply. 

Through the 1980s and 1990s, S.O. Sales built manufacturing relationships in the detection, fire suppression, and temperature control industries. As customers brought new requirements forward, the supplier base grew with them — matching custom components with manufacturers capable of meeting each program’s technical and quality requirements. 

Over time, that disciplined approach became the S.O. Sales model. Many of those customer and manufacturing relationships now span generations, with partnerships continuing since the 1980s. 

S.O. Sales combines the responsiveness and accountability of a focused U.S.-based organization with the capabilities of an established global manufacturing network. Rather than being limited to a single factory or process, we match each program with the right manufacturing capabilities, materials, and expertise.

Our responsibility extends beyond production. S.O. Sales coordinates supplier qualification, quality, inventory, logistics, and delivery as one managed process, helping customers maintain reliable supply, reduce complexity, and avoid carrying excess inventory.

Sue chose a dragon as the symbol of S.O. Sales when she founded the company in 1987. To her, the dragon represented protection, strength, wisdom, and good fortune — qualities that reflected the kind of company she wanted to build.

At the center of that idea was protecting what had been entrusted to S.O. Sales: customer relationships, manufacturing partnerships, and the responsibility that comes with supporting ongoing programs.

Four decades later, the dragon still stands as a reminder of that responsibility and the relationships built around it.
