About Us 

Our Veterinarians

Dr. Jon Bertoldo is the founder of Animal Mansion Veterinary Hospital. Dr. Bertoldo received his doctorate of veterinary medicine from Cornell University in 1994.  He began his veterinary career in Upstate New York and moved to New Jersey where he practiced both large and small animal medicine before specializing in small animal care full-time, and has been doing so for the past 20 years.

​In 2008, Dr. Bertoldo opened his own practice in the historic Hainesburg Mansion in Columbia, NJ.  In addition to veterinary medicine, Dr. Bertoldo's passions include photography, vintage cars, and spending time with his family.  

Dr. Shelley Parker joined the Animal Mansion Team in October of 2021. She is a undergraduate of Rutgers University and received her Doctorate of Veterinary Medicine from Ohio State University in 2001. As a seasoned Veterinarian, Dr Parker is accomplished in surgery, diagnostics and dental procedures. Her compassionate demeanor is demonstrated to both her patients and their owners.

​Shelley comes from a military family and moved frequently until settling permanently in Sussex County, New Jersey. In her non-professional life, she and her son spend much of their time tending to their horses. As avid equestrian, they both compete regularly in events in New Jersey and on the East Coast.

​Our Practice Manager

​Elyse Conway has been with Animal Mansion almost since its inception in 2007. While attending Rutgers University she worked as a technician, honing her adept skills and assisting Dr. Bertoldo. Throughout the years, she learned all aspects of the veterinary hospital. In 2019, Elyse became the Practice Manager and continues on occasion to assist with patients, while also training our technicians and staff. If anyone knows Elyse, they know that she is the "rock" of Animal Mansion. In her free time, Elyse takes care of her horses and pets and enjoys being with family and friends. 

Our Staff

Our practice would not be what it is without the group of highly skilled, patient and caring veterinary technicians as well as our compassionate and knowledgeable front desk crew.  We treat your pets like our own!  

The History of the Building

The historic Hainesburg Mansion was built in 1828 by architect Andrew Smith.   In its backyard are the remnants of the former Delaware, Lackawanna, and Western Railroad lines which ran alongside the Paulinskill River and feeds into the Delaware River.  It was sold to railroad tycoon Jacob M. Blair around 1843 and then acquired by Jacob Andress in 1885.  Andress and his family made the mansion their home for many years.  Since then, it has changed ownership many times, establishing itself as an inn, a restaurant, an ice cream parlor, even a speakeasy at one point in history.  In 2008, Dr. Jon Bertoldo acquired the Mansion in an attempt to maintain its Victorian charm and make it a veterinary practice unlike any other. It is more than just a veterinary practice, it feels like home.
