About Us

Mack Industries, Inc. was established in 1962 by John L McNulty. At that time there were three employees. John, his wife Liz and a mechanic. Liz McNulty operated the wholesale store, selling only a few of the basic controls needed back then for a boiler to operate. John and a mechanic would be bidding and completing jobs. In 1975 John L. McNulty III purchased the company, now nearly half a century later we have grown to twenty employees, still a small company but what is lacking in size is made up for in expertise and hardwork.
