HARTFORD -- Former Lt. Gov. Kevin Sullivan is making a return to the state scene. Gov.-elect Dan Malloy has tapped him to lead the Department of Revenue Services as its commissioner.

Malloy made the announcement on Wednesday at the Legislative Office Building. The revenue services department is the state's tax collection agency.

Sullivan, a Democrat who served as the state's second-in-command from 2004 until 2007, when he was replaced by Michael Fedele, will take over the revenue services position from Richard Nicholson.

"I've known Kevin for years, and while he's no longer a public official, that's never stopped his commitment to public service," said Malloy in a statement. "As commissioner, Kevin will draw upon his experiences and relationships borne out of his time in the Legislature to help Connecticut find new and innovative ways in which to collect the money it is due. I look forward to working with Kevin again."

"I'm honored that governor-elect Malloy believes my skills and experience will be of use to him in his administration," said Sullivan in a statement. "I'm looking forward to stepping back into public service on behalf of the people of the state of Connecticut."

A West Hartford native, Sullivan was elected to the state Senate in 1986 and served as its president pro tem from 1997 to 2004. Sullivan moved up to replace then-Lt. Gov. M. Jodi Rell in 2004 when former Gov. John G. Rowland resigned amidst a corruption scandal.

Sullivan, an attorney, did not run for re-election in 2006 and has served as the president of the Children's Museum in West Hartford since.

Sullivan graduated from Trinity College in Hartford and UConn Law School.

He is the second West Hartford politician added to Malloy's administration. State Rep. David McCluskey was previously picked to join the Board of Pardons and Paroles.

Former Department of Revenue Services Commissioner Tim Bannon, who served in that role under Gov. William A. O'Neill, is co-chairing Malloy's transition team.

Nicholson, the current commissioner, was chosen by Rell to replace Pamela Law, who retired in 2009 after seven years as the state's tax chief. Nicholson has worked at the department for more than 15 years and was previously its deputy commissioner and general counsel.
