Dr. Stephen Wilson & Katherine Wilson, Co-Owners
Katherine & Dr. Stephen Wilson, owners of Concord Animal Hospital (CAH) since 2015, live in Concord with their cats (Cookie & Meadow), dog (Petal), guinea pig (Beans), and two amazing children (Johanna and Peter).
Originally from Connecticut, Dr. Wilson grew up with Jack Russells, Corgis and Basset Hounds. He completed his undergraduate degree at the University of California, Davis, and then he worked in an immunology lab at Children’s Hospital, Boston, with an amazing team whose work was published in Nature Genetics.
As a child, he shadowed his brother-in-law, a large animal vet, and fell in love with caring for animals. He considered a few other careers, including wine making and a career in culinary, but was happy to fulfill his dream of becoming a veterinarian after graduating from the Tufts Cummings School of Veterinary Medicine. His wife thoroughly enjoys his superb cooking abilities and occasional home-brewed beer or cider. |
Katherine grew up Concord, attending Alcott, Sanborn, and Concord Academy. Her family included a rescue dog and cat from Buddy Dog as well as three West Highland Terriers - all patients of CAH.
She attended the University of Michigan and worked in finance before attending Tufts University to earn her MA in Education and then teaching at the Concord Middle School. After that, she earned her MBA from Boston College and spent seven years in market research and marketing. She is happy that all of these roles somehow perfectly aligned to prepare her to manage CAH! |
