      We so appreciate Knoll Animal Hospital being open in the midst of a world crisis. Our dog Goose woke up and we discovered she had quite the ear infection. She was in pain and we reached out to Knoll and they had procedures in place where they could see our dog, keep us safe and keep them safe during this time of world wide illness. They were professional, efficient and helpful. She was in and out and is feeling much better with medication. Thank you for being there for us!!

      I can’t begin to say how thankful I was to have located Dr. Pecoraro (now Knoll) for my timid, anxious Aussie-Lab, Zoe. I am willing to drive the 40-45 minutes for because of this care, as well as the rapport I and my “family” have with Dr. Knoll and her staff. We found local care after my “dog whisperer” vet had to retire after many years, but I knew in my heart Dr. Pecoraro was a special vet who I wanted to track down. We had a couple of “untimely needs” during our vets’ off-hours possibly a year earlier, once for Zoe and twice for an egg-bound Bearded Dragon. At those visits, Dr. Pecoraro demonstrated such patience and concern for them. When we needed to choose to euthanize our Beardie, Dr. Pecararo performed the procedure compassionately and demonstrated compassion regarding our loss. She also was proactive in discussing the diet and behavior changes that our male Beardie may exhibit related to mourning a Beardie he was not “housed” with; this aided in our keeping him interactive and healthy.

      Our 14-yr. old Aussie-Lab has suffered with reoccurring ear infections and is now fairly deaf, but happy. She receives what I consider the best skilled and compassionate care from both Dr. Knoll and her staff. They are gentle souls looking out for her well-being. Examinations typically were frightening and a challenge, but Zoe finds them less so under her care. Any procedures are discussed and performed with the pet patient in mind, first and foremost, and all options are presented. If anyone is looking for the best doctor, staff, and care, you can’t make a better choice than Dr. Knoll and her staff.

      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,
