Nathan TollettNathan Tollett
Director of Sales

Nathan Tollett began his hospitality career as an event manager at Houston’s George R. Brown Convention Center in 2002. He was the primary point of contact for the facility, assisting many major conventions in hosting and executing successful events. Following that, Tollett accepted a job as a national account executive with Visit Houston, where he booked a variety of meetings and conventions in the corporate and association market.

That experience as a hotel salesperson helped him round out the “hospitality trifecta”—giving Tollett the background from the facilities, destination and hotel perspective to better understand all of the aspects of the convention sales process. 

Tollett rejoined Visit Houston as Director of Sales in 2009 and now oversees the daily operations of the sales team while creating long term strategies relative to Houston as a premier meeting and convention destination. Most recognized for his creative client experiences, Nathan believes in providing targeted and customized solutions for all potential opportunities.

Meeting News honored Tollett in its 2009 issue of "Ones to Watch: 30 under 30” and he was also recognized in Connect Magazine as “Future Leaders of the Meeting Industry, 40 under 40” in 2011, and also received the 2015 Experient Supplier of the Year award.
