Shared Client Experiences
“We had the good fortune of engaging Gillis after years of managing our sales effort in-house. They came highly recommended through brand leadership and seasoned sales professionals, and they haven’t disappointed. Despite only a few months into our relationship, they have had an immediate impact on our hotels and key account relationships. The Gillis team has already established themselves as one of our most valued and trusted advisors and partners. They have always displayed the professionalism, passion and accountability demanded by their profession.”
– Perry Batke, CHA, General Manager, Denham Hospitality Organization
“The sales pros at Gillis have been instrumental in building occupancy at Motel 6 and Studio 6 hotels in Canada over the past several years. Working collaboratively with owners and managers, Gillis takes the time required to find and convert prospects to guests. Gillis provides a best-in-class solution for hotels that don’t have a dedicated, well-trained sales team.”
– Irwin M. Prince, President & COO, Realstar Hospitality
"As a management company with 4 smaller hotels in busy transient markets, we have struggled to keep our sales and marketing costs relative to the size of our hotel. The cost and time invested in attracting, training, and retaining good salespeople with the current job climate can be not only daunting but frustrating with turnover. With varying demand in the market, a sales manager needs to recognize when to take the business, and when to say no to it. The right rate, at the right time!
We have solved all these problems through turning this demanding role in 3 of our hotels over to Gillis Sales.
Gillis is a trusted, credible partner who has supplied me with experienced professionals who know the fastest route to the business I need. This has become our most effective resource, and I 100% recommend the Gillis solution to my colleagues."
– Patti Barker, Vice President of Hospitality, Metropolitan Hospitality Management
“We have a diverse portfolio of hotels, both full-service and limited-service. Having a company that can expertly do both is important. Gillis serves as a stand-alone effort for some hotels and, in others, is integrated with our on-site sales team to maximize revenue and efforts. This helps in responsiveness when opportunities present themselves and fosters a hands-on tailored effort for each location.
Their above-property team is also there for the more complex, non-routine issues, giving us confidence no matter what comes up. That kind of expertise and attentiveness has made all the difference. Another benefit is that the RDOS teams have hotel experience and understand the day-to-day nuances that our team faces and can adapt. This helps avoid delays or the sacrifice of customer experience as situations arise.”
