Dr. Gina Rendon, NYC Veterinarian

Gina Rendon, DVM, Medical Director

Dr. Gina Rendon joined St. Marks Veterinary Hospital in August 2013. Motivated by her love of the biological sciences and animals, she chose veterinary medicine as the "best way to pursue both these interests."

"I love that every day is different from the day before. You can never predict what cases you will see on a given day and that keeps things interesting," she said of her veterinary career. "Plus, getting to know the animals and their people is such a privilege, especially as you develop relationships over time."

Dr. Rendon earned her bachelor's degree in biology from Smith College, where she graduated cum laude with highest honors in neuroscience. She was also a member of Sigma Xi, the scientific research honors society. Interested in a career in behavioral research, she went on to earn a master's degree in brain and cognitive sciences from the Massachusetts Institute of Technology but then decided she "wanted a more hands-on approach and to work more directly with animals."

Dr. Rendon received her Doctorate of Veterinary Medicine from Tufts University School of Veterinary Medicine (now known as the Cummings School of Veterinary Medicine). She is a member of American Veterinary Medical Association, American Association of Feline Practitioners, Veterinary Medical Association of New York City, and the Vermont Veterinary Medical Association. Her professional interests include internal medicine and soft-tissue surgery. Before joining St. Marks Veterinary Hospital, she practiced veterinary medicine in Vermont, Massachusetts, and Quebec.

Dr. Rendon is married to Jon Nissenbaum, an assistant professor in the English Department at Brooklyn College. Their daughter Phoebe plays the cello and tuba and loves animals. Together the family cares for "the world's most handsome Puggle" named Roger and a Chihuahua mix named Otis, "who tries very hard to be a good boy, but sometimes isn't." In her spare time, Dr. Rendon enjoys swimming, running, walking with her dogs, exploring new restaurants, reading, watching movies, and visiting museums.

Dr. Lillian Chang, East Village Vet

ShuLing Annie Chang, VMD

Dr. Chang received her Bachelor of Science in Graphic Design Communications from Philadelphia University in 2006. After working in the marketing industry for several years, she enrolled in a post-baccalaureate program at Drexel University. She then earned her Veterinary Medical Doctorate degree from the University of Pennsylvania. Afterwards, she completed a rotating small animal internship in emergency, surgery & internal medicine at Veterinary Emergency and Referral Group in Brooklyn, NY. Her professional interests include surgery, emergency medicine, and preventative medicine.

Dr. Chang currently lives in Manhattan with her husband Anthony Sapienza, an orthopedic hand surgeon at NYU Hospital for Joint Diseases, and their feisty orange cat named Cinder. Outside of work, she enjoys skiing, painting, watching movies, exploring tasty foods, and eating lots of ice cream!

NY Vet, Dr. Catherine Stevenson

Catherine Stevenson, VMD

Dr. Catherine Stevenson grew up in Dover, Massachusetts. She decided to be a veterinarian upon completing high school, because it combined her two greatest passions--animals and science! She started out volunteering as an assistant with a small animal cardiologist, prior to completing her pre-veterinary studies in Boston. She obtained VMD degree from the University of Pennsylvania. After four years in Philadelphia, she moved to California to complete a one-year rotating internship at VCA San Francisco Veterinary Specialists, dividing her time between the emergency and critical care, surgery, internal medicine, neurology, oncology, cardiology and dermatology services. Currently, she lives in New York with her fiance and her two mischievous black and white cats, Michu and Mina. She has been an avid runner since high school; she also enjoys exploring NYC, photography, music, traveling and being outdoors as much as possible.

NY Vet, Dr. Mihoko Seki

Mihoko Seki

Dr. Mihoko Seki started here at St Marks Vet in 2016 and is a graduate from the University of Illinois College of Veterinary Medicine. She started her college career at Ohio State University which is where she realized that the love for her three family-owned dogs (Oreo, Chocolat, and Brooke) steered her into the direction of Veterinary Medicine. Dr. Seki transferred to the University of Illinois where she obtained her Bachelor’s Degree in Animal Science. While being a full-time student, she worked at the Vet School’s Diagnostic Microbiology Lab to learn more about our furry animals' diseases. This gave her incredible insight on our pet’s manifestations that are growing in and outside of their bodies. Dr. Seki enjoys performing surgery and working with exotic animals! She was trained in surgery at the Tampa Bay Humane Society. She also volunteered for the veterinary school’s Wildlife Medical Center for over 3 years diagnosing and treating unique patients.

Dr. Seki has lived in New York, Ohio, Japan, and Illinois. With all her relocation as a child, she developed the love for traveling and experiencing different cultures outside of this country. Dr. Seki enjoys watching soccer and has visited the last two World Cups (South Africa and Brazil), with the intentions of going to Russia in 2018! Aside from traveling, she is an avid fan of trying new foods and is enjoying the diverse restaurants NYC has to offer. She is currently living with a 2 year old kitten named T-Rex and he is as much trouble as his name!
