Walter is a man of his word! He prides himself in doing the tough jobs and doing them right. He and his team responded to our needs in a timely manner with great professionalism. When expectations were not met with the initial work, Walter made it right. You can trust this guy to do what he says he is going to do! Thank you, Gheller Management Group!

We have been using GMG Cleaning Services for two years now. The difference between Walter’s team and our previous cleaning company is tremendous and we were able to notice the change day 1. His team is punctual, very thorough, and they continue to go above and beyond our expectations. During this pandemic, GMG makes sure that we have all the necessary supplies and that all high traffic areas receives extra attention to ensure the safety of our working areas. Thank you, Walter and GMG Services for everything you do!!!

Walter and Liset are in regular contact with us about the status of cleaning, and what is/not being done. They respond quickly, and although we have some challenges, they continue to try to improve through communication and by working directly with their crew and our staff.

I have been using Walter and his crew for a few years now and he has always provided great customer service. He has been so easy to work with and is always quick to respond to any concerns or questions you have. The job is well done and any time we have had special requests or changes in schedule they are always so accommodating.
