Marian Coleman Retires after 34 Years of Service, Terrence Mann Promoted to DEO

After 34 years of service to South Coast AQMD, Marian Coleman retired in May 2020 as Deputy Executive Officer (DEO) for the Office of Compliance & Enforcement (OCE). Marian joined the agency as an Air Quality Inspector in 1986 and progressed up through the supervisory and managerial ranks until becoming DEO in 2018. Marian’s career is highlighted by her development of a robust inspection program to implement the state’s Portable Equipment Registration Program. She also demonstrated a tremendous commitment to the agency’s clean air mission and, through her leadership, made significant improvements to OCE by embracing the use of technology and promoting excellent customer service from all members of her team.

Terrence Mann, previously OCE’s Assistant Deputy Executive Officer, has been promoted to DEO. Terrence joined South Coast AQMD in 2018. Before that he worked for over a decade as a federal prosecutor with the U.S. Attorney’s Office for the Central District of California. Terrence prosecuted many cases involving criminal street gangs, fraudulent organized crime groups, and online child predators. Prior to his federal service, Terrence was a litigation partner in the Los Angeles office of the law firm McDermott Will & Emery, where he worked on complex civil matters and supervised internal corporate investigations. He has an undergraduate degree, magna cum laude, in history from Harvard University and a law degree from the UCLA School of Law.
