“We were very satisfied with the outcome of our recently designed multi-purpose room. It was better than we had imagined. We have had great reviews from the staff, administration, and residents. We have had good experiences working with HPS interior designers, and it was the right move to repeat our business. We encourage other HPS members to take advantage of the HPS design services.”

“In 2005 Ohio University made a significant change in our food purchasing bid process and became a prime vendor under the HPS college and university food purchasing program. Through negotiations with the manufacturers on firm pricing and through the prime vendor distribution program, we are able to maximize the rebate program with Gordon Food Service and save more than $100,000 annually.”
