Pre-VEG, Dr. Kozlowski practiced urgent care in Chicago. She worked in multiple New York VEG hospitals before opening VEG in Lincoln Park. She now brings her expertise to Oak Brook, where her fave aspects of the ER are the unpredictability, fast pace, and helping owners through scary moments with their pets. Owns two Great Pyrenees mixes and 2 cats, and says that if vacuuming were an Olympic sport, she’d have a gold medal thanks to her dogs!
