Groco® (Gross Mechanical Laboratories, Inc.) was born in the basement of a Baltimore row house in (approximately) 1918, with a pair of workers trained personally by founder Angus Roy Gross, Sr. This was a time when the entrepreneurial spirit flourished in America and when the industrial boom stood on the shoulders of an expanding steel industry and quickly growing automotive and marine industries.
