Michael Massari
Vice President of Meeting Sales & Operations

I have been in events my entire life, starting with a private catering facility in suburban Philadelphia. From there, I began working with meeting planners for Wyndham Hotels.

In 1998, I moved to Las Vegas to work as a National Sales Manager for the Venetian. At the end of 2000, opportunity knocked at the Rio, and I joined the team as the Executive Director of Sales & Operations. Together with my team, we created great results by having all departments that directly affect meetings report to one person. In keeping with the tradition of a streamlined reporting structure, I accepted the position of Vice President of Hotel Operations.

Caesars Entertainment presented me with an even greater opportunity. As Vice President of Meeting Sales & Operations - Las Vegas, I have been able to expand my vision across eight properties in the growing Las Vegas region. The meetings and conventions market is very valuable to the company, and our goal is to ensure that everyone has a successful event and a memorable experience. We want you to return, year after year, and enjoy the relationship that you have built with a team that knows you well.

Jordan D. Clark
Vice President of Sales - Caesars Entertainment

I began my career in the hospitality industry with a European hotelier whose philosophy on service was “Treat every guest as if they were a guest in your own home.” This adage impacts my decisions on a daily basis and fuels my desire to provide outstanding service to every customer. Since 1988, I have continued to strive toward this goal.

In 2000, I brought my dedication and enthusiasm to the best meeting destination in the world: Las Vegas. I chose the number one city in the world for meetings, so it only seemed natural to choose the number one meeting hotel within that city. I joined the Rio in 2004 after serving as Director of Sales East Coast for the Venetian and Director of Sales for Four Seasons Hotel.

The shared vision of all departments contributing to the success of a meeting is the perfect fit for me. With Caesars Entertainment, our success is not measured by how many new customers we attract, but by the number of customers who return. Delivering exceptional meeting experiences is my passion, and I look forward to serving you now— and in the future.

Don Ross
Vice President of Catering, Conventions & Events - Las Vegas

I have more than 26 years of experience in hotel, resort and casino management and was part of the Paris Las Vegas opening team. Before joining Caesars Entertainment, I held various positions in food and beverage at other esteemed hospitality companies, including Amfac, Hilton Hotels and the Hyatt Regency Atlanta.

As Vice President of Catering, Conventions & Events, I oversee the catering, conference services, banquets and meeting services departments for all eight Las Vegas Meetings by Caesars Entertainment properties. I serve as the primary agent of our one-stop, multiple-locale strategy, and work to make it easy for meeting planners to utilize multiple properties and venues within our Las Vegas family. Like the rest of the Las Vegas Meetings by Caesars Entertainment team, my goal is to create flawless, seamless, flexible meetings and events.
