The Catholic Diocese of Maine has hired Michael Magalski as its director of the Office of Professional Responsibility. Magalski replaces John Brennan, who is retiring after serving as the director since 2002.

The Office of Professional Responsibility investigates complaints that have been filed against members of the clergy, employees and volunteers of the diocese.

Magalski was previously the resident agent in charge for Maine for the U.S. Secret Service. He retired from that job in January after 17 years. During his time with the Secret Service, he handled investigations including fraud, high-tech computer crime and missing and exploited children.

Brennan was ordained as a deacon in 1998 and was previously the Portland Police Department’s deputy police chief.
