Regional Food Service Manager

Robert “Zac” Hurst graduated from the Academy of Culinary Arts at Indiana University of Pennsylvania (IUP), December 2003.  Following graduation Zac worked for Chef Glenn Wright at the Ritz-Carlton on Amelia Island, Florida. Here he not only worked in the banquet kitchen preparing meals for as many as fifteen hundred guests, but he also learned plating techniques and center of the plate presentations at the hotels "Café 4750."

Zac moved back to Pennsylvania to take a position as Chef de Cuisine at the Pittsburgh Athletic Association, a private club in downtown Pittsburgh, where he mentored under Executive Chef Ed Nagy.  Later, this team moved on to the 713 room Pittsburgh Hilton Hotel where they successfully ran a twelve million dollar a year catering operation as well as the daily meal services for the guests.

After his time at the Hilton Zac again followed his mentor, Chef Nagy, back to IUP and handled Campus Dining preparing daily meals for some three to five thousand students.  Using this experience as a springboard, Chef Zac branched out on his own with jobs on several college campuses in Pennsylvania, Massachusetts, and Maryland.  Finally, turning in a new direction, Zac discovered his own niche environment with employment first at Holiday Retirement and later with Hawthorne Senior Living.  As Executive Chef he found a real love in serving these communities. Most recently he has continued to serve as Food Service Director for Inhouse Rehabilitation Facilities and Senior Living/Continuing Care Retirement Communities.

On a personal note, Chef Zac was born and raised in Lansdale, PA and attended North Penn High School.  Currently Zac resides in Sinking Spring, PA. When he is not working Zac enjoys riding his Harley Street Bob, golfing, and travel.
