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!

      Knoll Animal Hospital is the best! Dr. Pecoraro & her staff are so caring. I've had to call in emergency situations, and they've always fit us in. Regular check ups are always stress-free, on time, and informative. I just brought Millie in for her regular check up and they treated her like a queen!Thank you for the great service you provide!

      I'm a believer that the best medical care is from local practices without oversized staffs. A vet that actually treats your pet like a patient and not a number. Dr. Pecoraro was referred to us by a close friend who knows a thing or two about animals. Best referral ever. Personalized attention, always willing to answer questions and incredibly knowledgeable. They recognize our dog on sight and genuinely care about him.

      Dr. Pecoraro and staff are honest, compassionate and always puts the needs of my pets first. I have a cat with a chronic condition, as well as a dog with anxiety issues. Dr Pecoraro and staff have managed to make visits less traumatic for both Ralphie and myself. She genuinely cares about the well-being of my animals. Unlike other clinics, I never felt as though any unnecessary tests or procedures are performed. I would highly recommend Dr P and staff to all pet lovers.
