They have expanded that to now include an institutional division that supplies pharmacuticals to correctional facilities, long-term care facilities and other businesses. Gilbert and Joan are currently vice president and president of the corporation, respectively, while Mark Zilner serves as the company’s COO.
The honor was announced in the May 4th-10th edition of the Pittsburgh Business Times, and join 20 other family-owned businesses in the Pittsburgh Region in receiving the honors. The awards were handed out at a dinner May 1st in Pittsburgh.
