Our People

It takes a lot of extraordinary people to make Waterloo Greenway an extraordinary park.

They’re champions of gnarled tree roots and curious waterfowl. Advocates of grass blades tangled in hair and sun-warmed benches. Staunch supporters of hip-shaking and head-bobbing and stewards of happy little giggles and big oohs and ahhs. They love everything that Waterloo Greenway is and will become. And they’re working hard to make sure that you love your park just as much.
