John P. "Rocky" Rockstroh Sr., a retired Bethlehem Steel Corp. supervisor and a senior partner in a firm that specialized in helping businesses reorganize, died Tuesday of lung cancer at Gilchrist Hospice Care. The Sparks resident was 69.
Mr. Rockstroh was born in Baltimore and raised on Foster Avenue in Highlandtown.

Mr. Rockstroh studied sociotechnical system designs at McGill University and at Goldratt Institute in New Haven, Conn.
He later became a partner in Beyond The Box Inc., a company that assists businesses in reorganizing their operations, family members said.
