Paul Decker, president of the Valley Forge (Pennsylvania) Convention & Visitors Bureau, will retire in March 2013. Decker, whose career has spanned nearly 40 years, began marketing Montgomery County, Pennsylvania’s meeting, convention and leisure visitor products in 1992 and helped guide the then-county government agency through its transformation into a private, non-profit destination marketing organization. The bureau has begun an initial search for Decker’s replacement.
