Who We Are

A few words about us...

Your pet isn’t cut from a mold. He or she has a special and truly unique personality. As such, the health care your companion receives should be just as exceptional.

At Knoll Animal Hospital, we believe that each and every patient we serve deserves to be treated like the individual he or she is. It is this personalized approach to medicine that makes our clinic so homey and inviting. Our team is genuinely passionate about helping animals enjoy longer, healthier lives and we’d love to help yours do the same.

We also believe that vet visits shouldn’t be cold and clinical. While we take our jobs seriously, we’re not afraid to let our hair down and have a little fun. Warm hugs and engaging conversation with our clients is as common around here as the extra snuggles and chin scratches we offer our patients. After all, that’s what being family is all about!

If you’re in the market for a Carol Stream or Glen Ellyn area vet, we sincerely hope you’ll consider giving Knoll Animal Hospital a try. We’d love the opportunity to provide you both with the personal care and attention you deserve. Call or stop by today!
