Mary Ann Dalgleish, ISCO VP (Membership) writes – “The President and creator of ISCO had a major birthday on December 29th. He turned 90 years young. David was also instrumental in the creation of SCAA and is still active at his company, Marine Pollution Control located in Detroit, Michigan. As most of you know, David was one of the first contractors active in pollution cleanup and a true pioneer in the development of the industry. Anyone wishing to send David a greeting can do so at his email: [email protected] Happy belated Birthday David Usher from all of us at ISCO”.
