Who We Are

A few words about us...

A Carol Stream or Glen Ellyn area vet you can trust!

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 in Carol Stream or Glen Ellyn 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 Carol Stream / Glen Ellyn 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. In fact, most of our staff is certified fear-free, which makes for a more positive experience all-around. Warm hugs and engaging conversation with our clients are 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 our Glen Ellyn / Carol Stream clinic today!

      Dr. Pecoraro and her staff are wonderful! Our Pomeranian had an eye injury and they got him in right away. Dr. Pecoraro was great at explaining what was wrong and what could have caused the injury. The follow up call to see how he was doing was appreciated. We are very happy to have our pets taken care of here. Please consider Countryside Animal Clinic for compassionate, skilled and reasonably priced care for your pet.
