Daniel Leiman

DVM & Owner

Dr. Daniel Leiman co founded the Northside Veterinary Clinic with Dr. Barbara Eisner in 1996.

Dr. Leiman graduated summa cum laude from Duke University undergraduate and then graduated with honors from Cornell Veterinary School.

As a veterinarian with over 40 years of clinical experience, Dr. Leiman loves to teach clients how to best care for their pets.

"I believe each patient is a distinct individual, and tailor my recommendations based on the age, breed, and conformation of that particular animal. My two guiding principles are from the writings of Hippocrates - first, do no harm, and let food be your first medicine."

In his free time, Dr. Leiman enjoys hiking with his kids and his dogs.

Barbara Eisner


Dr Barbara Eisner graduated veterinary school from the University of Pisa.

As a veterinarian with 36 years of clinical experience, Dr Eisner's mindset is to look for the trigger for diseases so she can then use the best modalities to not only treat the problem that exists, but to try to make sure the problem doesn't recur. Besides being a surgeon and using western treatments, Dr Eisner uses acupuncture, craniosacral, cold laser, shock wave, and Chinese Herbal Medicine to treat her patients.

Dr Eisner is on the board of the NYS Complementary and Alternative Veterinary Medicine Association and has certifications in veterinary acupuncture and Chinese Herbal Medicine.

Dr E spends her free time practicing martial arts, riding horses, and providing acupuncture as a volunteer at an equine rescue barn.

Maegan Ramos


Dr. Ramos was born and raised in Houston, TX where she realized early on she would build a career around animals. She attended Texas A&M University for her undergrad career where she majored in Biomedical Sciences with a minor in Business.

During this time, Dr. Ramos began volunteering at veterinary clinics and animal shelters which solidified her desire to attend veterinary school. She completed her degree in Veterinary Medicine from Texas A&M in 2015 and immediately started her career in Houston.

She recently relocated to Brooklyn with her boyfriend, her dog Hollie and her cat Jack Jack. In her free time, Dr. Ramos loves reading, exploring the local parks, and having coffee at her local coffee shops.

Dr. Stacey Leiman is the newest Veterinarian joining Northside Veterinary Clinic. Dr. Leiman received her Bachelor of Arts in Psychology and Ethics from Emory University in 2015, followed by her Post Baccalaureate from Columbia University in 2017, and her Doctorate of Veterinary Medicine from Cornell University in 2022. Her areas of professional interest lie in international and domestic volunteer work with veterinary medicine.

Dr. Leiman has loved animals since the day she was born, and jumped into the veterinary field at 16 years old when she began assisting at Northside Veterinary Clinic. She described her passion for this field came from seeing her parents be so fulfilled by their careers. Dr. Leiman loves being able to give back to the community locally and internationally, by keeping her patients as healthy and happy as she can.

Originally from New Rochelle, NY, Dr. Leiman now resides in Brooklyn with her rescue animals, two cats (Phoenix and Artemis) and a dog (Gordi) adopted from her time volunteering in Cozumel, Mexico! When Dr. Leiman is in the office, she enjoys educating her clients on the science and pathology behind everything, as once upon a time she wanted to be a science teacher. Outside of work, she fills her time with reading, yoga, hiking, and continuous volunteer work. Some of her efforts included teaching college age women in Cambodia and Tibetan monks in India!
