Matthew Steinberg, DVM
Dr. Steinberg is a native Long Islander, he grew up on the North Shore of Nassau County in Roslyn, N.Y. He spent his summers teaching and riding horses and has always had a propensity towards animals and nature. Dr. Steinberg graduated from Tufts University School of Veterinary Medicine in 2005. Following veterinary school, he continued his training completing a rotating small animal surgery and medicine internship at the Animal Medical Center in New York City and spent the following year as an emergency veterinarian at Bluepearl Specialty and Emergency Hospital also in New York City. Dr. Steinberg spent most of his early years practicing as an emergency veterinarian working alongside various specialists as he honed his practical skills. He spent another 2 years practicing high-quality veterinary medicine as a general practitioner on the upper East Side of Manhattan.
In 2010, Dr. Steinberg moved back to Long Island to continue practicing the highest level of veterinary medicine focusing on general practice with a keen understanding of your pet’s emotional and medical needs as well as the ability to communicate effectively with you, the client and pet parent. He continues to focus and teach the value of working with pet owners to improve their pet’s lives.
Most importantly, Dr. Steinberg spends much of his time when not taking care of our beloved pets with his two children, twins, Daniel and Hannah. They are everything to him and if you come in many days you might see them helping around the office! Between the animals that live at the office and home, Dr. Steinberg has a zoo, caring for two dogs, an Aussiedoodle Lily, and Cavapoo Sandy, and eight cats Salt, Pepper, Millie, Puck, Mario, Betty, Stanley, and finally Sabrina! And if you visit the office you will meet our tortoise, “Torti”.
His special interests in veterinary medicine include neurology, emergency medicine, and especially being the bridge between owners and pets helping people keep their pets happy and healthy.
Dr. Hayley Knopf
Sometimes we feel helpless. Helpless in knowing where our pet might be hurting, why our older dog may be slowing down, what the best plan for our new puppy or kitten is, why our pet won’t eat, if they are sick, or whether that bump is concerning. Is a certain behavior normal, or could it be a sign of a deeper health issue? There can be so many questions. This is where my passion lies. To be able to provide you with answers, so your best friend can live a happy and healthy life, and be by your side for as long as possible.
