About Marvin

Marvin Klein is the founder of PortionPac Chemical Corporation, headquartered in Chicago. In 1964, PortionPac pioneered high concentrate detergent formulations, portion control packaging and environmentally sustainable programs. Dozens of concepts from safer chemicals to color coded products and formal janitorial education were introduced to the cleaning industry through PortionPac. His goal has always been to improve the effectiveness of cleaning on health and productivity while reducing environmental impact.

Many of his business concepts were formed by outstanding high school teachers and professors at the University of Illinois. After graduation, he worked for the Ekco Products Company before military service as an Army Intelligence Officer. Since 1956, he has worked in the janitorial, food service and corrections industry to improve professionalism, safety, and recognition for maintenance workers.

He is proud of his contribution to many organizations including the Child Nutrition Foundation and the Chicago Manufacturing Center and is currently on the Boards of the Healthy Schools Campaign and the John Howard Association for Prisoner Rights and the Compression Institute.

He and his wife Bobbie have been married for 58 years and have three children plus five grandchildren.
