Daniel Leiman, DVM

Daniel Leiman, DVM

Daniel Leiman, DVM

Founder and owner of Northside Veterinary Clinic. Although he grew up in Elmont,  New York with dogs and cats as beloved family pets, Dr. Leiman did not develop a passion to be a veterinarian until his undergraduate years at Duke University. After graduating Summa Cum Laude from Duke, Dr. Leiman was admitted to the Cornell University College of Veterinary Medicine.

After working in Amish country in Bloomsburg, Pennsylvania for two years at a mixed animal practice, Dr. Leiman returned to New York City, where he completed a two-year internship at the ASPCA's Henry Bergh Memorial Animal Hospital. After practicing at the Queens Veterinary Emergency Clinic and other small animal practices for several years, Dr. Leiman began his own housecall practice.

The housecall practice grew quickly, so Dr. Leiman needed to establish a practice where people could come to see him as well. With his wife, Dr. Barbara Eisner, the Northside Veterinary Clinic was founded in 1997, at 233 Berry Street in Williamsburg, Brooklyn. Dr. Leiman no longer makes housecalls, but sees patients and perfoms surgical and dental procedures at the clinic regularly.

Outside of work, Dr. Leiman enjoys playing racquetball, playing bagpipes, rooting for the Yankees and keeping his pitbull on a short leash.

Barbara Eisner, DVM, CVA

Barbara Eisner, DVM, CVA

Graduated college as a chemist and worked both for Lever Brothers and General Foods for a number of years before applying to vet school. It was no surprise that Dr. Eisner gave up chemistry to become a veterinarian as helping animals had always been her true passion.

Dr. Eisner graduated from the University of Pisa, Italy and worked for other vets before establishing the Northside Veterinary Clinic with her husband, Dr. Daniel Leiman. She obtained certification in Veterinary Acupuncture from the International Veterinary Acupuncture Society in 1998, and is a member of the American Academy of Veterinary Acupuncture. Dr Eisner performed much of her equine acupuncture internship at New York's Belmont Race track and her small animal internship with International Veterinary Acupuncture Society instructors.

She also trained in Chinese Herbal Medicine at Tufts University and has completed numerous courses in Chinese and Western herbal medicine.

In her spare time, Dr. Eisner likes to ride horses and practices martial arts.
