Great Events Of Colorado
Established in 2008, GEC is a dedicated team of events services managers who carefully prepare pre-show and put our boots on the ground during operations to plan, integrate and deliver robust staffing solutions for wide-ranging programs and clients.

Team GEC partners with organizers and promoters of Denver Metro sport, entertainment, corporate and civic events - and citywide accommodation and parking venues - in the planning and delivery of guest services, secure venue access controls, licensed security patrol and certified traffic mitigation.
Services
Great Events was started in 2008 out of necessity. While managing concerts and other large events at Fat City Entertainment Greg Tomasello developed the need for temporary staffing. The service from these contracted temporary staffing companies was not up to the standards set within our operation, thus jeopardizing our image and therefore our business.
We are committed to providing our customers with superior level of service and expertise in our industry. To do this we have implemented a wide range of services and products that are considered to be industry standards in business across the nation. We aim to transfer this expertise to you the customer giving you the necessary skills and resources to manage your business and market it successfully.
Our experienced staff, and expert coordinators have serviced events and venues of all types in Colorado area for over 10 years. We hire only the best local professionals who have a track record of excellence and service. Choose us to handle all your event staffing needs. Having the right people and event staff in place assures that you can focus on keeping your production on track, and providing the attendees with best possible experience.
Greg Tomasello is an operations specialist with more than 25 years of experience in large venue management. He has directed major theme parks across the US and Africa, IE Raging Waters Water Park (San Jose, CA), White Water Canyon (San Diego, CA), Morey's Piers (Wildwood, New Jersey), Boomers Fun Parks-San Diego, & Vista locations (San Diego, CA) and Wave House (South Africa) are to name a few.
GEC's extensive experience in providing security and other services for Fairgrounds events makes us uniquely qualified to fulfill the requirements for multiple event types. The "inside information" our veteran staff members have acquired from working previous events will be invaluable in enabling them to provide exemplary service.

Greg and his team have been a huge asset to our production company over the years and always go above and beyond in terms of filling gaps and problem solving. When it comes to parking, his team will always find a way to increase your parking capacity safely and effectively.

By far the best and most personable Special Event Parking & Security company i've worked with. Great Events was able to maximize our event parking to accommodate another 20% of participants and make both the inflow and outflow run smoothly. I use them on all my events!

We have used Great Events of Colorado to handle parking and traffic flow at many of our running events over the last decade. Greg and his team do an amazing job. They are professional, easy to work with and highly skilled. I would recommend them to anyone in need of a parking and traffic flow solution.

Management needs a change of attitude, Tyra is amazing.... however Greg (the owner) is disorganized and easily disrespected by his staff due to his lack of leadership.
The company has good potential and is easy to work for however some of the supervisors are power hungry and are bringing the overall performance of the company down.

A group of hard-working, good hearted people that do an excellent job at keeping people safe. A security company with a quality for that gentle but firm touch, so people enjoy the events but still feel safe.
