GMG Services

Commercial Cleaning

When we started our business in mid-2016 we quickly realized that our clients needed more than just a cleaning company. They needed a partner that they could trust to get the cleaning job done without being involved so that they could focus their time on what was important: “running their business”. Today GMG Services is the trusted partner of more than 40 businesses in Minnesota..

Walter and Lisete, the owners of the Gheller Management Group (GMG Services), bring over 70 years of global commercial experience to their business and to Minnesota. They have worked in many countries and have extensive experience in Business Administration, Business Process, Communication, Security, and Commercial Cleaning.

They quickly realized that most cleaning companies failed on 2 critical items: “Flexibility” and “Communication”. When they started GMG Services, they made a commitment to respond to their clients’ requests within an hour, and this is what they have been doing ever since. They also understood that their clients’ businesses would grow and that they needed grow with them. GMG Services changes and adapts according to the clients’ needs. Nothing is set in stone.

With GMG Services you have a great partner because we are always ready and capable to help you with any project that arises, so that you have more time look after your business. We provide a holistic service that is far superior to any other. In other words, you can relax while we do the work. GMG Services is committed to excellence.

What Our Clients
Say About Us

I have been nothing short of impressed by this company ever since they started cleaning for us. They are professional and thorough, and our place has never looked so good. Our last cleaners would come to clean, and then I would hear the complaints afterwards. What I hear now is, “This place has never looked so good!” Walter and his professional top quality cleaning crew have really made the difference in our day to day ops at Brunk. Best decision we’ve made to hire them!


Linda Bartlett

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!

Magdy Rabeaa

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!!!


Arthur Farber

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.


Sheila Przesmicki

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.
