Dr. Arns is originally from Sussex County, NJ, but then spent several years in upstate NY and CT. She graduated from Cornell's College of Veterinary Medicine in 1997, and started out working on horses. She quickly moved to small animal practice. She has worked in the NJ/NY metro area since 2000, first in White Plains, NY, then Crestkill, NJ, and now in Rutherford, NJ. Dr. Arns enjoys seeing pets of many species including birds, reptiles, and small mammals such as, rabbits and guinea pigs, as well as dogs and cats.

Away from the office she spends time with her husband David and their cats Cody, Skylar, and AJ. She enjoys running, showing model horses, and seeing Weird Al Yankovic in concert (she met her husband at a weird Al show!)
