Message from Founder

With more than a decade of development, CaSO has accomplished an extraordinary milestone, which we are extremely proud of.

We were a small firm back in 2004, and now we are harvesting the fruits of our labour. We are glad to see what we have built up in terms of social and professional recognition in the industry over the last decade. However, our ambitious mission "to transform our building environment from harm to harmony together with our professional team" has remained the same as it was a decade ago.

At the same time, we are committed to do business in a socially-responsible way. We pledge to care about both personal and professional development of our colleagues as well as the community we operate in. In this rapidly changing environment with increasing environmental concerns, we constantly strive to develop and introduce new technology and products that would not only meet, but also further exceed the on-going needs of our markets, customers and the environment.

With the vision of CaSO being "to serve our clients and the community with sustainable material and practices", I could foresee a period of development and growth which shall take us all at unprecedented heights. I am sure that my team will continue the good work with CaSO's future looking bright with aspirations and goals.
