LYNN — When Bruce Silverlieb, 61, was a 15-year-old growing up in Swampscott, he took a babysitting job to make extra spending money. That job set the trajectory of the rest of his life.

He started making dinner as part of his babysitting duties. Parents hired him whenever they entertained, and word spread. At 16, he printed his first business cards. The Party Specialist was born.

In April 1982, Silverlieb rented the space at 530 Chestnut St. in Lynn and The Party Specialist has called it home ever since.

A lot has changed in the event planning industry over 40 years, Silverlieb said. Small plates and passed hors d’oeuvres have replaced formal sit-down dinners. Production Manager Tammy Choquette of Lynn, Head Chef Richard “Richie” Mintzer of Swampscott, and Silverlieb are all certified in Food Allergy Awareness to accommodate a dramatic increase in special diet requests. Choquette joined the business in 1983 and Mintzer one year later.

Although The Party Specialist is primarily a catering service, clients sometimes request that the team organize the entire event. They have handled events for 3,000 people and tented affairs with a field kitchen lacking access to water or electricity. “Our adaptability allows us to create very special parties even in the most difficult situations,” Silverlieb said.

Silverlieb also works with clients to accommodate unusual requests, such as orchestrating a performance by silk trapeze artists over the guest table in a Boston castle or arranging fireworks displays as a bride and groom depart in a helicopter. “I like being the guy who says ‘yes,’” Silverlieb said with a smile.

He attributes his four decades’ longevity to three things: this “say yes” philosophy, his insistence on quality, and the loyalty and experience of his staff.

“In an industry known for high turnover, we boast an amazing team,” Silverlieb said with pride about the people who feel like family as much as employees. “It’s not unusual to have three generations of staff at a party,” he added.

SIlverlieb, who lives in Marblehead with his husband Dr. Mark Korson, admits that surviving COVID as a small business was the hardest challenge of his career, but is optimistic. “I just want to keep doing exactly what I am doing now,” he said.
