I proofread it and have made a couple of small alterations. Some typos corrected, some wordings changed. But overall a great mission statement...

Recognizing this fact, we have taken the opportunity of combining advanced technology with time-honored values of courtesy and responsibility, and have come up with a highly efficient yet refreshingly personal service.
Our drive for excellence and personal care makes us responsive and sensitive to the quality of service we provide our business partners. Our professional service team continually develop new techniques and methodologies in cleaning maintenance. Our objective and pride is a client satisfied.
