Woman owned, two generations strong.

Woman owned, two generations strong

In 1974, Lynne Colker, a business graduate from Carnegie Mellon University, purchased a small distribution company specializing in sea sponges. In just a few short years, L.M. Colker Co. grew to selling ladders and cleaning supplies. Lynne’s son Greg and daughter Sandy grew up in the business, helping dry and pack sponges, working summers while in school.

Sandy took over the helm, in 1999, becoming President, joined by Greg, who runs the retail side and Bill Hanberry, Sandys husband. The team has expanded the family business, still at the original location in Pittsburgh’s Strip District by adding a storefront, repair department, hosting Lunch n’ Learns, and more.
