SMG client - Connecticut Science Center
“I just want to let you know how appreciative we are of SMG’s custodial services here at the Connecticut Science Center. The service is excellent and the personnel you selected to work with us are great. No request is out of the question and usually can be accommodated within the current budget and in a reasonable timeframe.

SMG has a very responsive team and is an easy company to work with. I’ve enjoyed our partnership since SMG joined us back in June 2009 when we opened to the public. Our patrons, staff and visitors frequently comment on the very noticeable cleanliness of the facility. SMG’s customer support at all levels is first rate.

Being a fairly new facility we have high expectations for our cleaning service partner to keep the facility looking new. Whenever challenging situations occurred SMG’s response was always a calm willingness to analyze and meet each challenge. Thanks again for all of your help making the Connecticut Science Center a premier center for learning science while having fun in a clean and healthy facility.”
