Olin B. “Buddy” Campbell Jr., an official of the YMCA of Greater Rochester, has been named chief executive officer of YMCA Buffalo Niagara, it was announced Monday. He will succeed John Murray, who is retiring in February after 25 years as CEO.

Campbell, a native of Batavia, has been senior vice president for association advancement at the YMCA of Greater Rochester for the past 11 years, helping to increase membership by 165 percent and increase revenues by 108 percent. The Rochester YMCA is roughly twice as big as the Buffalo Niagara Y.

Campbell joined the YMCA in 1973 while still a student at Brockport State College. He worked for the Genesee Area Y in Batavia until 1982, then joined the Rochester Y. From 1988 to 1999, he was chief operating officer for the Buffalo Niagara Y, working with Murray to greatly expand the child-care program, open a new branch in Lancaster and create financial surpluses for nine straight years.

“We are thrilled to have secured Buddy Campbell as our next CEO,” said Anthony Spada, chairman of the Buffalo Niagara Y’s board of directors. “He knows Buffalo, he knows our Y and he will hit the ground running in February.”
