The Brookline Community Foundation finds itself suddenly starting a search for new leadership following Monday’s departure of Richard Ward as executive director. Judith Kidd, chairwoman of the nonprofit foundation’s board, has stepped up as interim director. In an interview Wednesday, Kidd said she expects to be at the foundation “practically full time” to “ensure the continuation of all our programs.” The most critical, Kidd said, are the foundation’s grant program, which will be accepting applications this spring, and the annual Spring Appeal, which raises funds to support the Brookline Safety Net operation at the Brookline Community Mental Health Center. Ward was hired to lead the foundation in May 2010, and oversaw the launch of its Youth Philanthropy Initiative as well as successful fund-raising campaigns. Kidd said he left to pursue other opportunities. Calls and e-mails to Ward were not returned. Kidd said the board will be looking for a new executive director with strong ties to the town who will share the foundation’s values and vision for a better Brookline. - Andreae Downs
