"Burbank is a great community that pulls together," she said.
Organizers wanted to bring together the agencies that make Burbank a great place to live, Frommer spokeswoman Lissa Zanville said.
More than 50 booths ringed the open grassy area and it was the first time the block party included a health fair and rides and games for children, she said.
Hailey Heath, 7, was busy taking several laps on a small train ride as her grandmother, Donna Martyn, looked on.
"I mostly want to go to the booths and get free candy and stickers and pencils," said Hailey, who was wearing a sticker that looked like a Burbank Fire Department badge. "The train ride was good but there was dust flying in my eyes. The slide is the best."
Frommer mingled freely with the crowd, fielding questions and compliments from some and promising to help other constituents with their problems.
"It's a nice opportunity for people to come out and meet their neighbors and get some information about the agencies in their community," he said.
"A lot of people came here to ask me about an issue they want me to check into. I think it makes people more comfortable to talk to me now than when they come into my office."
While many politicians and celebrities avoid large crowds, Frommer believes this is a way to make himself more accessible.
"It's part of your job," he said.
"You represent 450,000 people in the district. This is how you maintain contact with your constituents."
The city of Burbank, NBC Universal, Kaiser Permanente, Woodbury University, Burbank Fire Fighters union and AT&T co-sponsored the event.
