“I just want to share with you more positive feedback from our tenant Jill in 3A09. Jenny did an amazing job cleaning their classroom last week on very short notice. Great job Jenny, keep it up!”

“I wanted to take a moment and express to you the tremendous job that Judith has been doing for us. Hardly a day has gone by without a positive comment from one of our staff members who have observed Judith’s thorough commitment to a job well done. Judith always arrives to work in a timely fasion, keeps me informed of her lunch schedule, and leaves when the work is complete. She is always professional and courteous in the interactions that I have witnessed with staff and visitors alike. Often in the service industry you do not get the full credit due if no one takes the time to express it. I did not want her impeccable work ethic to go unsung. It is an absolute pleasure to have her here with us.”

“Jamie Navas is dependable and maintains a positive attitude when performing his duties. He is self-motivated, well organized and able to prioritize in order to meet deadlines while working with minimal supervision. He takes the initiative to get the job done. No job is too small or too big. Jamie is an outstanding asset of the Mister Kleen team.”

“During our transition from one building to another there has been constant support from Tasha. She notices small things and takes care of them without us asking. She is so proactive about things in our office. I wanted to ensure you were aware of her efforts.”

“I really want to let everyone know you have a great group at our building. One Friday the cafeteria drains stopped up and it was a mess. I asked Shannon for help cleaning and as always she jumped in with no questions or excuses. Shannon and her staff Steven & Tori are a big help when there are emergencies like this.”

“It is with great appreciation that we pass along a huge thank you for the excellent service Mr. Kleen’s Team, headed by Yolanda Rathbone, preforms on a daily base for our business. We have occupied the same space for over 15 years and our tile floors barely look passed just a couple years old. Time after time, we receive great compliments on how fantastic our print shop looks!”

“Professionalism and going the extra mile are everyday common happenings for Yolanda and her crew. No task asked goes without immediate resolution. We appreciate their hard work and service to us individually, and the building. Thank you, Yolanda!”

“WE WOULD LIKE TO TAKE THIS OPPORTUNITY TO THANK YOU and your staff for your assistance as we were preparing 5301 Wisconsin Avenue for the BOMA Building of the Year Awards. An exercise of this kind requires an enormous amount of teamwork from the employees, tenants and vendors serving the property, and we would not have been successful without your efforts. You and your team worked tireless hours to complete all of the projects at hand, which is a testament to your dedication to servicing CBRE.”

“DAY-TO-DAY OPERATIONS AT A 160,000-Square-foot STATE-OF-THE-ART FACILITY such as Eckington Place is a wonderfully demanding adventure in itself—from the latest in floor coverings to miles of exposed cable trays and polished conduits, to the over 450 employees with a common ambition to share our exciting new product with the nation. We depend on a level of cleanliness that amplifies our facility to be enjoyed by all. Mister Kleen has provided XM with this kind of care and personal attention since the day we first occupied the third floor here. While completing construction of our state-of-the-art, on-site live studios, and finishing the lower levels, Ernie and Dianna have been consistent in providing the quality care we expect here at XM. As a facilities manager, it is a pleasure to work with a company who strives to meet our specific needs.”

“MISTER KLEEN RESPONDED QUICKLY AND PROFESSIONALLY to a water extraction and mold prevention job.  Their quick response prevented thousands of dollars of damage.  We will call them in the future.”
