Alliance, Ohio-based Robertson Heating Supply held a recent customer-vendor event at its 285,000-sq.-ft. facility as part of its 80th anniversary celebration.

The invitation-only expo attracted about 775 people, including employees, contractors and vendors with guests coming from Ohio and western Pennsylvania. Robertson has hosted similar events for its top customers every five years since the current facility opened in 2004.

About 240 contractors and 77 top vendor-suppliers attended the event. Vendor-suppliers offered special show anniversary deals. Similar expos are scheduled in August at the Cleveland Browns’ stadium and at Heinz Field in Pittsburgh, Pa.

Special guests included former Ohio State football coach and recently appointed president of Youngstown State University Jim Tressel and Rheem NASCAR driver James Bueschler, who appeared with his stock car.
