Torrenga Engineering, Inc. was founded in 1960 by Alfred P. Torrenga. The firm grew in a short period of time to be one of the most comprehensive engineering and surveying firms in Northwest Indiana. Mr. Torrenga's background included a BSCE from Purdue University, assistant Lake County Highway Engineer, Highland Town Engineer and Griffith Town Engineer, a post he held for 18 years until his death in 1982. A veteran of World War II, serving as a Captain of Engineers in the Pacific Theater, Mr. Torrenga subsequently served in the Indiana National Guard and rose to the position of Lieutenant Colonel in the Army Corps of Engineers. Torrenga Engineering is now operated under the direction of his two sons Gary P. Torrenga, and Donald C. Torrenga.
