What our clients say about us...

April 2017
Absolutely love the team at Knoll! We took our dog here shortly after adopting him years ago, and they were fantastic. Every paranoid dog-mom moment I had, they were always there. Even now that I have moved to Texas I have still called them asking questions. Wish I could have taken them with us on our move. They love your animals like they love their own. Great people, great practice.

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. Annjolyn Pecoraro-Knoll is amazing. I'm sad that we are moving away from such a great vet. She definitely puts her heart & soul into caring for our furry babies. She's very knowledgeable & answers all questions & takes time to listen. Our 2 rescue dogs have been very well cared for by her. I definitely recommend this place.

Dr. Pecoraro is one of the best veterinarians I've ever experienced in my fifty-two years of owning a pets. She also has the most caring and competent staff that are always willing to spend time answering all questions and concerns. This office truly cares about animals and not just what's in your wallet.

Dr. Pecoraro in a word is #AWESOME! She treated my little Grizzly Bear with such care and compassion as well as me and my family. I am so grateful to have met her that day we spent together during Jury Duty she is not only a great person but an Awesome vet. My experience has been nothing but positive with her and the staff from my first visit to my latest where she had performed a very delicate surgery to remove a mass on my G Bear's neck. Thanks to her and her staff we have more time with him. The excellent medical care, compassion and competitive pricing at Knoll Animal Hospital is more than I could ask for. If I could give her 10 stars I would. I HIGHLY recommend Dr. Pecoraro to anyone searching for a Veterinarian; you and your furry children will be glad you did.

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.

Countryside is the best. Dr. Pecoraro is wonderful with my dogs. She explains what is going on and gives me care options. The staff is very friendly and care about the animals. The staff or the Doctor always followup to make sure my dogs are responding to the treatment. Great place.
