Trained in virtually every aspect of veterinary care, the Northvale Veterinary Clinic staff provides the care your pet needs – from preventative to illness and injury. It doesn’t matter if your pet is in need of a simple immunization or requires in-depth care for a neurological problem, we are here to help.

Dr. Stefanie Simon, DVM

A New Jersey native, Dr. Simon graduated from Union College in Schenectady, NY with honors and an undergraduate degree in biochemistry. She pursued her dream of becoming a veterinarian at the University Of Illinois College Of Veterinary Medicine during which time she volunteered at the Wildlife Medical Clinic.

Now the proud owner of Northvale Veterinary Clinic, where she feels privileged to provide care for pets in need, Dr. Simon is known for the deep understanding and compassion she offers every visitor that enters her clinic. A member of the American Veterinary Medical Association, she also works hard to assist rescues in need and one day putting an end to animal cruelty.

When not taking care of pets at the clinic, Dr. Simon enjoys freestyle skiing, golfing, hiking, camping and travelling the world. Most of her spare time is spent with friends and family, including her cats Jerry and Freud who remind her every day of Immanual Kant’s famous quote: “We can judge the heart of a man by his treatment of animals.”


Practice Manager

Cristina, a former veterinarian technician, studied at Penn Foster College in order to fulfill her lifelong need to help as many animals as possible on a daily basis. Her passion for animals is evident in the focus and care she provides for each and every clinic patient – no matter size, shape or species. During her free time she helps take care of stray cats around her neighborhood, helping many of them get spayed and neutered in order to help prevent feline health problems and overpopulation. She spends much of her time with her cats as well as many of the dogs she’s rescued from the streets. Intent on saving helpless animals and the planet itself, Cristina is an expressive advocate for many of the global issues regarding animal rights and the environment.
