AUGUSTA, Maine — Robert A. Williams of Vassalboro was nominated Monday to be the next chief of the Maine State Police.

Williams is a 27-year veteran of the state police and has served for the past four years as the deputy chief of the department, holding the rank of lieutenant colonel.

If confirmed by the state Senate, Williams will succeed Col. Patrick Fleming, who has served as chief for the past four years.

Public Safety Commissioner John Morris recommended the 47-year-old Williams to Gov. Paul LePage, who nominated the lieutenant colonel for the post.

“Lt. Col. Williams has the experience, vision and qualifications to serve as state police chief,” Morris said in a statement issued Monday. “In the past eleven years, he has overseen every aspect of the department, from the troopers on patrol, the dispatchers who answer the calls, the technology essential in today’s law enforcement world and the department’s budget and funding sources.”

Williams’ nomination will go before the Legislature’s public safety and criminal justice committee, which will hold a public hearing on his selection sometime in the next few weeks.

Williams joined the state police in 1984 after serving as a police officer in Pittsfield for a year. He patrolled in Somerset and Kennebec counties as a trooper and later as a patrol sergeant. He was promoted to lieutenant in 1998 to oversee the state police communications division and the four regional communications centers in Gray, Augusta, Orono and Houlton. In 2000, Williams was promoted as one of the department’s two majors, overseeing, at different times, operations and support services. He has served as deputy chief since 2007.

Williams is a graduate of the University of Maine at Augusta and holds a master’s degree in administration from Husson University. He is also a graduate of the FBI’s National Academy in Quantico, Va. In addition to his state police career, Williams is a volunteer firefighter in Vassalboro and previously served as a volunteer firefighter in Pittsfield.

Williams grew up in Pittsfield and is a 1982 graduate of Maine Central Institute. He lives with his wife, Joyce, in Vassalboro and they are the parents of two daughters — Courtney, 17, a senior at Waterville High School, and Ashley, 20, a junior at the University of Vermont.
