Emergency & Critical Care

Margaret Thies, DVM

I grew up in Maryland but over the course of my education have lived in Ohio, Minnesota, Washington, and Massachusetts. I find animal physiology and behavior fascinating, which led me to study zoology in college and to work and volunteer with dogs, cats, exotic animals, and wildlife.

I am happy to be back on the East Coast. I live in Maryland with a crew of adorable adopted brachycephalic dogs and cats. In my free time I enjoy reading, group fitness classes, hiking, and cooking new recipes.

Why Do You Work at Friendship?
