From Dr. Zerrenner: “At the age of 5, my Kindergarten teacher asked me what I wanted to be when I grow up and my answer was “a veterinarian”. My mom tells me that I only mentioned one other career as a child and that was to be a bus driver after being thrilled and exhilarated by my first bus ride. I have been with employed at the Oradell Animal Hospital for about 25 years. I continued to work part-time during the two years while I was completing my residency at AMC. My favorite things about veterinary care are the babies. I love puppies and kittens, especially when they are healthy.”
