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!

      I brought my bulldog mix CoCo in for an emergency and everyone was so wonderful!! Dr. Clark deserve so much praise for literally saving my little girls life! She explained everything so well and even kept us updated after her surgery. I would highly recommend Knoll, they are just as concerned for your pet as you are. Thanks again everyone!

      I have been going to Dr. Angela Clark for over 10 years and I can't imagine going to anyone else. Although new to Knoll Animal Hospital I believe you will find that she gives the same excellent care that you have experienced with Dr Knoll. She explains everything that is easily understood, gives you options on how to move forward. Shares her concerns and pros and cons concerning treatment. She is open to new and different ideas and if not comfortable with a medical situation she does NOT hesitate to inquire with other Drs. what might be the best way to proceed. I find that refreshing as she puts the care of the animal before everything. I think you will find she is an excellent addition to the already wonderful staff at Knoll Animal Hospital,
