Practice Manager

Brian Niezabitowski

Brian Niezabitowski started working for Kremer Veterinary Services in January of 2018. He is currently the Operations/Practice Manager at the Animal Care Center of Downers Grove location. Brian graduated from De La Salle High School in Chicago, Illinois. He then went on to start his degree in Criminal Justice at Moraine Valley Community College.

What inspired Brian into going in to the Veterinary industry, was that one day he had to take his dog in to see the Veterinarian and he was blown away on how great the staff and doctors were with not only himself, but his dog as well. After speaking with a couple of the employees as well as the doctor about the company, he soon applied and as the saying goes, the rest is history. One of Brian’s favorite things about working in this field is that every day is different. It can go from being very slow to crazy hectic in a matter of minutes! To him, that is so exciting!

Brian currently has 2 dogs: 4-year-old Havanese named Sofie and a rescue dog named Parker who is also 4. Both have completely different personalities and that is what makes them the greatest dogs according to Brian. He is married as of September 2017 to his beautiful wife Tori; they do not currently have any children. Brian does enjoy watching the Cubs and Bears play (tougher being a Bears fan these days)! If Brian is not at work, you can find him at home working on home improvement projects or out fishing.

Kind Words from Happy Pet Parents!

Dr. True is one of the kindest people I have ever met. He is so wonderful with my Dog. He gets down low on the floor with him, very gentle and always concerned. He speaks so politely and professionally to me and always listens to whatever I have to say. I cannot say enough great things about him! -Clare C.
