Third generation members of the family include David Rosen as president and Adam Rosen as executive vice president. Winsupply is the majority owner, reflecting its shared-ownership business model in which local entrepreneurs have autonomy to decide how best to serve their customers, and to share in the financial risks and rewards of ownership.

“Rosen Supply has a stellar reputation in western Washington and has grown substantially with nearly 70 employees providing supplies for residential repair and replacement, and commercial plumbing, primarily new construction, and showroom business,” says Monte Salsman, president of Winsupply Acquisitions Group. “This is a well-managed company with an entrepreneurial spirit that matches perfectly with the Winsupply model that we call The Spirit of Opportunity.”

"We are very excited to be joining forces with Winsupply,” says David Rosen. “Winsupply is one of the top plumbing wholesale distributors in the nation. This new partnership will allow us to significantly increase our presence in the market."

Harvey Rosen decided to sell the company to Winsupply as an opportunity to keep some ownership in the family. “My sons and nephews have all been managers and earned their stripes. They’re all well rounded in the business and have great rapport with our customers.”

The company’s legal name becomes Winsupply of Seattle WA Co., but will continue to do business as Rosen Supply.
