William Cotcher

Floral and Display Director

William joined Planterra in 2005, bringing along more than two decades of floral and horticultural experience. He leads a team of professionals as our floral and display director. William manages the creation of all floral and décor displays for events. You’ll find him working on everything from crafting stunning bouquets or boutonnieres to one-of-a-kind centerpieces or garlands and unforgettable entry displays. If a bride can imagine it, William can bring it to life with flowers.

He is a graduate of Michigan State University. Before joining the Planterra team, William worked at Boston’s Baugh Haus Collaborative and Harding Botanicals. When he’s not creating memorable displays, he can likely be found in the garden or renovating his Auburn Hills home. William also spends plenty of his free time cooking or spoiling his nieces and nephews.
