Early life and family

Denn was born in Wilmington to Morton Denn, a Distinguished Professor of chemical engineering at the City College of New York, and Marilyn Denn. He grew up in suburban Hockessin and moved to Berkeley, California during high school. A graduate with honors and student body president at the University of California, Berkeley, he received his law degree from Yale Law School in 1991. He now lives with his wife, Michele, and twin children, Zachary and Adam.

Professional career

Returning to Delaware in 1991, Denn worked for two years with Delaware Volunteer Legal Services and then went into private practice, becoming a partner with the law firm of Young, Conaway, Stargatt & Taylor in 2000. He was awarded the Distinguished Service Award from the Young Lawyers Section of the Delaware State Bar Association. In 1998, he was appointed chairman of Delaware's new Child Protection Accountability Commission, a commission set up in the aftermath of the deaths of several children in state care.

Political career

As Governor Ruth Ann Minner's legal counsel from 2001 through 2003, writing legislation including the Patient's Bill of Rights and the Emergency Health Powers Act.[1]

Denn first ran for a seat in the State Senate in 1998 against incumbent State Senator Bob Conner. He lost that race but was elected State Insurance Commissioner in 2004, defeating Karen Weldin Stewart in the Democratic primary race, and later defeating Republican Party candidate, Dave Ennis, a member of Delaware General Assembly, in the general election. Denn served as Insurance Commissioner from January 4, 2005 until January 4, 2009.

Lieutenant governor

Denn announced in March 2007 that he was a candidate for Lieutenant Governor of Delaware in the election of 2008. Another Democratic candidate, Wilmington City Council President Ted Blunt, ended his campaign in spring 2008, avoiding a primary. Denn took more than 61 percent of the vote, defeating Republican candidate Charlie Copeland in a statewide Democratic landslide. He took office in a ceremony just after midnight on January 20, 2009.[2] As Lieutenant Governor, Denn has focused on issues affecting children.[3]


Elections are held the first Tuesday after November 1. The Lieutenant Governor takes office the third Tuesday of January and has a four-year term.[4] The Insurance Commissioner takes office the first Tuesday in January and has a four-year term.[5]
