Our involvement in the community.

At CSi we like to give back to our community.  Check out the video of some of our work with the Sixth Street Shelter:

Since 1984, the Sixth Street Shelter has been providing temporary housing for Lehigh Valley homeless families with children.  Today, the Shelter proudly offers 25 individual family apartments.  It is the only shelter in the Valley to offer homeless families the privacy and security of a furnished apartment with a complete kitchen.
