Delta Sigma Pi hosts open house St. Thomas Newsroom September 28, 2009 Delta Sigma Pi, a professional, co-ed business fraternity open to students of business and economics, will host an open house this evening. Informational sessions were held last week, but the fraternity still welcomes and invites interested students to attend the open house from 6 to 8 p.m. Monday, Sept. 28, in McNeely Hall. The open house will include speakers and a chance to ask questions of fraternity members. Business professional dress is encouraged; refreshments will be served. “Delta Sigma Pi is a great way to get involved and to develop professionally throughout your college career,” remarked Kristin Seifert, a Delta Sigma Pi member.
