About Us

Animal Mansion Veterinary Hospital

A practice unlike any other, Animal Mansion Veterinary Hospital is located in the historic Hainesburg Mansion in rural New Jersey.  The Hainesburg Mansion was built in 1828 by Andrew Smith and sold to Jacob M. Blair around 1843.  With the Delaware, Lackawanna, and Western Railroad lines formerly running in its back yard, the Hainesburg Mansion was eventually purchased by railroad tycoon Jacob Andress and made into a residence for he and his family in 1885.  In 2008, Dr. Bertoldo procured the estate and transformed it into Animal Mansion Veterinary Hospital. Its picturesque location in the historic Hainesburg Mansion provides a comfortable and unique veterinary experience that you won't find anywhere else.  

Dr. Jon P. Bertoldo

After graduating from Cornell University, Dr.  Bertoldo began his veterinary career in Upstate New York working in a predominantly large animal practice.  Over twenty years ago, Dr. Bertoldo moved to New Jersey and transitioned from a mixed large and small animal practice in Sussex County, to a small animal practice in Warren County.  In 2008, Dr. Bertoldo opened his own practice in the historic Hainesburg Mansion.  Dr. Bertoldo currently serves on the Cornell University College of Veterinary Medicine Alumni Board.
