South Charleston Mayor Frank Mullens is scheduled to participate in a ribbon-cutting ceremony Friday at Pulmonary Associates of Charleston's new office building across from Thomas Memorial Hospital in South Charleston. The ceremony will be at 11 a.m. at the two-story building, which is just off MacCorkle Avenue, directly behind Long John Silver's.

The doctors are Tom Takubo, Kevin Eggleston, Rob Keith, Alex Wade and Ed Gray. Chris Long is the operations manager. Tammy Flowers is the office manager. Pray Construction of Scott Depot was the project general contractor.
