Ms. Clayburn worked with the community service board of Mr. Grecco's organization.
"But when layoffs came in manufacturing, construction, steel, electrical and the needle trades, we just couldn't keep up with the supply needed to help people," he said. "Brenda organized food drives, and when we had meetings, we were to bring canned food to them. "
Mr. Grecco said there were times when he and Ms. Clayburn didn't see eye to eye.
"But I valued her role. If she thought I was doing something wrong, she'd chew [me] out," he said, laughing. "She told it like it was. She never sugarcoated it."
He said that Ms. Clayburn could be a "tough negotiator."
"I'm sure she was a dynamite negotiator. She had confrontations at times, but they were never on a personal level," he said.
For her exceptional community service, Ms. Clayburn was awarded the United Way of Central Maryland's Philip H. Van Gelder Award in 2009.
"There is a lot of competition for that award, and only one person gets it," said Mr. Grecco, whose organization nominates recipients.
In addition to her work, Ms. Clayburn had been a longtime active member of the National Association for the Advancement of Colored People. As a young woman, she had participated in the historic 1963 March on Washington, where she heard the Rev. Martin Luther King's "I Have a Dream" speech.
A community advocate for mental health and substance abuse, Ms. Clayburn had been a member of the Bon Secours Community Institute of Behavioral Services Advisory Board and had served as its treasurer. She also had been president of her Druid Park community association.
Ms. Clayburn enjoyed traveling and visiting Maryland beaches, her daughter said.
"She also like spoiling my two daughters — her granddaughters — and collecting glasses with the names of places she had visited," said Ms. Cooper.
Ms. Clayburn was a member of Mount Olive Freewill Baptist Church.
Plans for services are incomplete.
She is survived by her daughter and her two granddaughters. Her marriage ended in divorce.
