Kask & Company completed our 2025 Food Drive with impressive results.

Along with many boxes of non-perishable items, Kask employees delivered $2,000 in cash donations this year. The donations were collected from our generous clients, friends and employees. We thank everyone who participated this year. Supporting our neighbors in need is another way of celebrating this holiday season while strengthening our community.
