Four alumni of the University of Rochester with expertise in business and finance will begin serving on the University Board of Trustees this month.

"A great university deserves a strong and committed Board of Trustees," said G. Robert Witmer Jr., chairman of the board. "We are delighted to welcome these four very accomplished and loyal alumni, and we look forward to having them join us and President Joel Seligman in setting and achieving the exciting goals worthy of our alma mater."

He earned his doctoral degree in optical engineering from the University in 1969, and is the 2002 recipient of the highest alumni honor given by the School of Engineering and Applied Sciences.
