Courtney Knopps, Practice Manager

I have been around animals my whole life so joining the Grass Lake Animal Hospital team in 2013 was the perfect fit for me. I can't remember a time when I didn't have pets, ranging from cats to bunnies to lizards. My grandpa was a dairy farmer so I also spent a great deal of time on his farm when I was younger, enjoying the outdoors and learning about his trade. I live in Grass Lake with my two cats, Murphy Bean and Ophelia, both of which are rescues. I'm the crazy cat lady (but yes, I also LOVE dogs), and if you don't believe me, my whole bathroom is decorated in cats. If I'm not here you can usually find me with family or friends. I have two nephews, Henry and Jacob who are my world. I also enjoy reading, football (Go Pack Go!), and riding my motorcycle.

Hi! I have been in veterinary medicine for 20 years and have been a licensed veterinary technician for 18 years. I am married to my childhood sweetheart and we have a 7 year old pitbull named Gunny and a 20 year old green iguana name Jabberwocky. When not caring for your pets, I enjoy being outdoors and reading a good book.

Jennifer Craig, Receptionist

Hello, I'm Jennifer. I always knew I wanted to work with animals. I spent my summers growing up on my grandparents ranch, helping in any way I could. My schooling took me in a different direction until 2020, when I started at Grass Lake Animal Hospital. I have been married for 8 years and have 2 dogs, Memphis and Gemma, and 3 cats: Squish, Nash, and Kovu. I am fluent in Spanish, I love to study history, travel, and just be outdoors.
