The late Marvin Zisman, whose motto was “Always take care of the customer,” started Ambassador Home Improvements as a wholesale home improvement products distributor. Son Joe (left) joined in 1971, becoming president in 1988. But through the early 1990s, he couldn’t breach $2 million, even adhering to his father’s maxim. Then an industry friend and supplier told Joe of a new, high-end, energy-efficient window and suggested he streamline his offerings. Dealer Newpro shared marketing, sales, and training methods. Soon Ambassador was selling Newpro’s Quantum windows. Ambassador’s volume last year topped $5 million, and the company now sells only windows and doors. Zisman, CEO, has a crackerjack management team, headed by president Bruce Butterfield (right), a Newpro alum, who leads day to day while Zisman develops vision.

Ambassador guarantees a 40 percent energy savings with its Quantum II replacement windows. The company has done so well, it’s expanding its central Pennsylvania territory to include the eastern portion of the commonwealth.

Custom software allows Ambassador to monitor sales, marketing, and financial stats, so it can pinpoint strengths and weaknesses, giving it a chance to tweak operations daily. Its installation team boasts a statistic few others match: Less than 1 percent of revenues goes toward servicing callbacks.
