Dr. Sarah Laabs, DVM


I attended Michigan State University for undergraduate studies prior to earning my Doctor of Veterinary Medicine from the University of Missouri. After veterinary school, I worked in a walk-in emergency and general practice outside of Chicago before moving home to be closer to family. My professional interests include dentistry and preventative medicine. I love spending time with my family, which includes my husband, two daughters, and black Labrador (Breslin – go green!). In my free time, I enjoy home renovation projects, playing piano, traveling, and spending time with my girls! I can’t wait to meet your furry family member!

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 (and yes, I also LOVE dogs), and if you don’t believe me, my whole bathroom is decorated with 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.

Mary Ortiz, LVT

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 share a home with a 7-year-old pitbull named Gunny, and a 20-year-old green iguana named Jabberwocky. When not caring for your pets, I enjoy being outdoors and reading a good book.

Veterinary Assistant

Hi, I am Ginny. I have been a Veterinary Assistant since 2015. I graduated with my Associate of Arts Degree in St. Charles, MO in 2015. In 2017, I married my high school sweetheart and then moved here to Michigan. I have two dogs, a 7-year-old Great Dane Mix and a 6-year-old Lab Mutt. When I am not working, you can find me either camping or fishing on the lake.

Hello, I’m Jennifer. I always knew I wanted to work with animals. I spent my summers growing up on my grandparent’s 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 eight years and have two dogs, Memphis and Gemma, and three cats, Squish, Nash, and Kovu. I am fluent in Spanish, and I love to study history, travel, and just be outdoors.
