Dr. Jennifer Chu is a native of New York City, having grown up in Bayside, Queens. Her love for animals started at a young age. While she wasn’t allowed to have dogs or cats, the house was a zoo of hamsters, guinea pigs, parakeets and even a snake. Dr. Chu graduated with honors from The Pennsylvania State University, where she studied Animal BioScience. Always a fan of sports, she was a part of the PSU Gymnastics Club and attended all of the football games. After Penn State, she was awarded a partial scholarship to attend Western University of Health Sciences in Southern California, where she earned her veterinary medical degree (DVM) with honors.
Since completing her graduate studies, Dr. Chu has been trained in many aspects of the veterinary field, including small animal emergency medicine, shelter medicine, soft-tissue surgery, diagnostics and general practice. She even spent time providing health care and surgeries at the American Fondouk- a free veterinary clinic for dogs, cats, donkeys, rabbits, etc. in Fez, Morocco. The practice had very limited supplies and technology.
Dr. Chu joined Lower East Side Animal Hospital from The Pet Health Clinic at the North Shore Animal League America (NSALA) in Long Island. At NSALA, she cared for both rescued animals from the shelter as well as owned pets. During her time in general practice, she has developed a keen interest in ultrasonography and ophthalmology as well as soft-tissue surgery, and hopes to further her education in radiology while working at LESAH.
Outside of work, Dr. Chu hangs out with her sweet Dachshund / Chihuahua mix, Cupcake, and loves to snowboard, go to the beach, and travel as much as she can! She looks forward to developing a long-lasting relationship with the clients and their four-legged family members at Lower East Side Animal Hospital.

Team Members – Licensed Veterinary Technicians
I’ve been an animal lover since I could crawl on my own four legs! Stemming from the upstate region, I began my career in the Veterinary field in 1999. I spent 7 years working with small animals and helping rehabilitate wildlife including bald eagles, hawks, owls, squirrels, rabbits and possums. I’ve also worked with ‘pocket pets’, iguanas, snakes, McCaws, Cockatoos, and African Greys. I received my license to practice Veterinary Technology in 2005, and joined Heart of Chelsea in 2008 where I remained until the opening of their sister hospital, Lower East Side Animal Hospital, in August 2013. I’ve had the privilege of working with virtually all types of creatures and my passion in this field continues to grow each day towards being an advocate for our and your pets which we consider family.
It took me a little while to finally decide that I wanted to care for and work with animals for the rest of my life. I knew that being a teacher, dentist, or even a scientist would leave me unsatisfied and unfulfilled. Working as an intern in two wildlife rehabilitation centers confirmed that I could not do anything else. Now as a licensed veterinary technician, I am whole and always excited to go to work and continue to help owners and animals alike. Although I can no longer practice wildlife rehabilitation due to my busy schedule with work, my cats, and my saltwater and freshwater fish tanks, I am at least able to consult with other wildlife rehabilitators on cases when they need advice.

After graduating, Deric spent six years as an emergency ICU technician in California before returning to New York City and finding a place to call home in our Heart of Chelsea/Lower East Side Animal Hospital family.
