Gail Glasser, president and chief executive officer of the YMCA of Central Kentucky, resigned Thursday.
Tom Harris, vice chairman of the YMCA board, said the voluntary resignation "caught a lot of people by surprise."
The resignation was announced to the YMCA's staff Thursday.
"It has been my sincere honor and privilege to serve the Fayette, Scott and Jessamine County area through my 31/2 years with the YMCA of Central Kentucky," Glasser said in a statement. "The Y's commitment to youth development, healthy living and social responsibility through the work of staff, board and volunteers is vital to the health and well-being of our community. My family and I have enjoyed our time here and look forward to watching all the great work to come." She gave no indication of her future plans.
YMCA board chairwoman Christie Hockensmith said YMCA chief operating officer Tom Blackman would serve in Glasser's capacity while a national search for her successor was launched.
Glasser came to Lexington in September 2008 from Houston, where she was senior vice president of association advancement for the YMCA there. She also had been a vice president for financial development at the YMCA of Greater St. Louis and had worked for the Washington University Campus YMCA-YWCA.
The YMCA of Central Kentucky has centers in Lexington at Beaumont Centre, on High Street and in North Lexington, and in Scott and Jessamine counties.
