Modest Beginnings. BIG Dreams.

RES History

Respect the past. Work hard to ensure a future.

Early Years
For 30 years Vince Leonardo managed the in house tradeshow department at Rochester, New York based, Bausch & Lomb, one of the world’s largest suppliers of eye health products, including contact lenses, lens care products, medicines and implants for eye diseases. When the company decided to out-source the department, Vince started RES (Rochester Exhibit Services) and his first major client was Bausch & Lomb. Vince also opened an event company, LT Rentals, to serve both consumer and trade event business.

Both businesses prospered and after 20 years, Vince turned the company reins over to his son, James Leonardo, who has led the growth of RES, becoming one of the nation’s top 50 tradeshow and event organizations – named by EVENT MARKETER magazine in their annual profile of top industry performers.

Given our heritage, RES has one foot in the corporate world and one foot in the service world. This combination provides the RES team with visibility into the needs, wants and expectations of our corporate clientele AND insights into the services and resources needed to drive tradeshow and event program performance, today and tomorrow. The end-result: YOU COMMAND THE FLOOR in a hyper competitive tradeshow filled with competing stimuli and the noise of business.
