L.L. (Butch) Weldy founded Weldy Associates in 1946. Weldy-Lamont Associates, Inc. was formed in 1971 when Dennis W. Lamont purchased Weldy Associates upon L.L. Weldy's retirement.  In 2004, Patrick J. Hennelly and William T. Heberer became the third generation of owners of the company.


In 2012 the company was divided into two separate business entities: Weldy Lamont Group, Inc. and Weldy-Lamont Associates, Inc. Weldy Lamont Group is the domestic manufacturers' representative side of the business. Weldy-Lamont Associates, Inc. is the international side of the business performing EPC projects in Africa. Each company operates independently from each other and operate in separate locations.

In January 2016, Weldy Lamont Group welcomed its fourth generation of owners as Joseph L. Bolsinger, and Kyle C. Johnson purchased Weldy Lamont Group shares from Patrick J. Hennelly and William T. Heberer. 

The company operated from the same Chicago address from 1947 to 1977, when Weldy Lamont Group, Inc. relocated to 1008 E. Northwest in Mount Prospect, Illinois. In 2012, after expanding through the years and outgrowing our existing building, Weldy Lamont Group moved to 1040 W. Northwest Highway, also in Mount Prospect.


In July 2020, Weldy Lamont Group moved to its present location at 3201 Tollview Drive, Rolling Meadows, IL 60008-3705.
