Wingspan — a center that serves lesbian, gay, bisexual and transgender communities — will close its doors July 31 because of financial difficulties.

The nonprofit organization at 430 E. Seventh St. has served LGBT clients for 26 years and has experienced financial difficulties since 2009, said Paul Guerrero, president of Wingspan’s board of directors.

“The board voted to begin collaborations with the Southern Arizona AIDS Foundation to discuss a transition that will allow for Wingspan’s programs and mission to continue,” said Guerrero, noting that discussions with other nonprofits are also underway.

Wingspan’s current budget is $665,000, and half of the money is covered by grants and contracts, said Guerrero. He said the remainder is raised through donations and fundraising.

“After the recession, we got hit hard,” Guerrero said. “All of our major donors suffered from the recession. It has been downhill since 2009.”

The organization released its executive director, Carol Grimsby, last week. Her annual salary was $70,000, plus benefits, Guerrero said. He said overhead expenses also increased over the years, and he expects this fiscal year Wingspan will end owing about $25,000.
