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. 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 today!

      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.

      I have been going to Countryside for about a year and a half. Dr P has been absolutely amazing to me and my pups. I honestly can't say enough kind words about her and her amazing staff. If you want caring, compassionate, and loving people talking care of your four legged family members, you've found the right place.

      We are so happy we found such a wonderful place to keep Bunny healthy and the purple poodle is the bomb for great grooming.

      I took both my dogs there to have their teeth cleaned. They were gentle, kind and very professional. All of my questions were answered and my dogs were well taken care of. I would highly recommend them.

      Dr. Pecoraro is such a caring and compassionate doctor. My animals LOVE her!!! My dog, who is normally over excited and anxious going to the vet, always seems at ease with her. Being the neurotic pet owner that I am, she has always taken the time to answer my many questions and then makes a follow up phone call the next day to see how everything is going with my pet! That was such a sweet, unexpected thing that no other doctor (including my own) has ever done before that it won me over to make Dr. Pecoraro our animals forever doctor back in 2013. We raved about her so much that all my local family switched vets and now takes their pets to see her. It's such a comfort knowing that your animals health is in good hands and we are so glad we have you.

      Dr. Pecoraro and her staff are outstanding! The animals always come first, as it should be, but their "bedside manner" for the families of the animals they treat is the perfect blend of warm, friendly, and professional. I also appreciate the efforts that have been made to introduce more technology into the clinic operations, and freshen up the overall appearance of the office.

      Dr. Pecoraro and Paulina were a blessing when it came time to say goodbye to our senior German Shorthair Pointer Elle in April 2016. The arrangments they made to make the experience as comfortable as possible were absolute perfection, and the care and compassion they showed were just off the charts. If I could give them more than 5 stars, I would gladly do so.
