About Our People

Our Community


We actively support our community in a variety of ways. One of our favorites is our role in the Gateway Warrior Foundation golf tournament, where we frequently raise more than $1,000 in donations each year with the Waterway Wheel. The funds raised by the foundation help sponsor Honor Flights and pay for the training of service dogs.

Our O’Fallon location has recently become involved with the Folds of Honor golf tournament. Folds of Honor raises money and provides scholarships for family members of veterans wounded or killed in the line of duty.

We also provide a Waterway Scholarship for business students at Pattonville and participate in employee fairs at Hydromat and Worldwide Technology.
