State Treasurer Tim Cahill will be the next speaker in the 2010 Gubernatorial Speaker Series presented by the Rappaport Center for Law and Public Service at Suffolk University Law School.

Cahill, who left the Democratic Party and will run for governor as an independent, will meet with a roundtable of senior policymakers, nonprofit leaders, representatives from the business community, lobbyists, lawyers, faculty, and students. He will speak and take questions from noon to 1:30 p.m. Monday, March 22, at Suffolk University Law School 120 Tremont St., Boston.

The series will continue April 7 with Republican businessman Christy Mihos.

Democratic candidate Gov. Deval Patrick will take part on May 24.

Republican Charles Baker, former CEO of Harvard Pilgrim Health Care, kicked off the Gubernatorial Speaker Series on Feb. 4.

The Rappaport Center’s Speaker Series affords the gubernatorial candidates a forum to discuss policy issues they think are important to Massachusetts voters and to identify their priorities.

The event is open to the Suffolk University Law School community and invited guests.
