Special Events Services — Est. 1996 · Saint-Laurent, Montréal
S.E.S is Special Events Services. A family-run AV company built on trust, service, and 30 years of turnkey productions.
From a music store rental desk to a full-service, turnkey production house.
S.E.S stands for Special Events Services. Founded in 1996 by Valerio Zeffiro, the company was built on a straightforward idea: give customers great service, and handle the entire technical side so they never have to worry about it.
With a background in music and hands-on experience managing the rental department at Italmelodie — one of Montréal’s best-known music stores — Valerio saw that clients didn’t just need equipment. They needed a partner who would show up, solve problems, and deliver a finished experience. That meant turnkey solutions from the very beginning: sound, lighting, video, staging, and the crew to run it all.
He started S.E.S in a small warehouse in Saint-Laurent with a simple belief: the right equipment, delivered with the right expertise and genuine care, can make any event unforgettable. That belief took hold quickly. What began as a modest operation outgrew its walls, and over the next three decades S.E.S quadrupled in size.
As the industry evolved, so did we. S.E.S has always adapted to follow industry trends through the years — from live streaming and video walls to LED technology, hybrid events, and the latest in audio and lighting innovation. Whatever the format demands, we make sure our clients have the tools, the expertise, and the service they need.
Today, Valerio works alongside his son, Anthony Zeffiro, who is next in line to lead the company. They are currently working together, combining decades of experience with a fresh perspective, until Valerio retires.
What makes us who we are is simple: we are a trusted partner, we deliver great customer service, and we invest in state-of-the-art equipment. We do what we promise, and when a customer is in a pickle, we are always there to help them through it.
