Special Report

Guy MingoThe Case for Vendor Consolidation, by Guy Mingo, CEO

“With Marsden Holding, customers get a national presence with local dedication,” says Guy Mingo, CEO of the St. Paul-based commercial cleaning powerhouse. That statement seems to be the unofficial motto of the company as the phrase is reiterated by not only Mingo, but several of the presidents of the companies Marsden Holding has acquired.

Comprised of 23 companies operating in 46 states, it’s easy to see what Mingo means about national strength. However, to understand the other part — being a local player — one simply has to look at a few of Marsden Holding’s larger acquisitions: SCIOTO Services of Columbus, OH; Aztec Facility Services of Houston, TX; or CleanPower of Milwaukee, WI. None are known as Marsden Holding, but rather they maintain their vitally important regional identity. Complete story here.
