Mel Florczak retired Friday, ending a 20-year career as director of the Buffalo Convention Center.
Paul Murphy, the assistant director, will assume the position of acting director of the downtown Buffalo facility with 35 employees. He takes over Monday.
Murphy left his position as general manager of the Beaver Hollow Conference Center in Wyoming County to join the Buffalo Convention Center last month.
The Buffalo Niagara Convention and Visitors Bureau, which operates the center, announced Florczak's retirement Friday.
"We are grateful for Mel's many years of dedicated service and wish him and his family well in his retirement," said Buffalo Niagara CVB President Richard Geiger.
The convention center hosted 229 functions, including conventions, meetings, trade shows and parties, with more than 420,000 attendees in 2000.
Murphy was director of convention sales for the Buffalo Convention Center from 1993 until 1997. He is also a former director of convention sales for the Niagara Falls Convention and Visitors Bureau.
A search will be conducted to select a permanent replacement for Florczak, according to the Buffalo Niagara CVB.
