Northside Veterinary Clinic
offers the best in both complementary and standard treatments for the
health and wellbeing of animals, and opens the door for a positive
relationship between caretakers and their pets.

 

Dr. Daniel Leiman, DVM, along with
Dr. Barbara Eisner, is the founder and owner of the
Northside Veterinary Clinic. Although he grew up in
Elmont NY 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 College of Veterinary Medicine.

He graduated Cornell Vet School with honors in 1981.
After working in Amish country in Bloomsburg, PA for 2 years at a
mixed animal practice, Dr. Leiman returned to NYC, where he did a 2
year internship at the Henry Bergh Memorial Hospital. After working at
the Queens Veterinary Emergency Clinic and other small animal
practices for a few years, Dr. Leiman began his own housecall practice.
The housecall practice grew so quickly that Dr. Leiman needed to set
up a place 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. Although Dr. Leiman still makes housecalls, the
majority of his time is spent practicing medicine, surgery and
dentistry at Northside.
Outside of work, Dr. Leiman enjoys playing racquetball, playing bagpipes,
rooting for the Yankees and keeping his pitbull on a short leash.

 

Dr. 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 she 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
forming 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 did much of her equine
acupuncture internship at 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
taken numerous courses in Chinese and Western Herbal Medicine.
Dr. Eisner likes to ride horses and practices martial arts
in her spare time.

 

Dr. Eric Mondschein, DVM grew up in
Miami Beach, Florida. 
He attended undergraduate school at the University of Florida where he received a
Bachelor of Science in animal science as well
as wildlife ecology and conservation. 
Dr. Mondschein received his Doctorate
of Veterinary Medicine from Tufts University
College of Veterinary Medicine in 2007. 

He also received a Master in Public Health from
Tufts University College of Medicine.  Dr. Mondschein’s interests
include emergency and critical medicine, public health, and emergency
preparedness for animals. He currently practices veterinary medicine
in New York City where he lives with his wife, Wendy, and orange cat,
George.

 

Erica Harmon, Licensed Veterinary
Technician, earned her Associates in
Applied Science and is a 2011 graduate
of the LaGuardia Veterinary Technology
program.
She also received a Bachelor of Arts in
Photography from the University of Delaware
in 2003. Although the arts remain close to her
heart, she is happy to have settled into a
career which fullfills her true passion:
making a positive difference in the
lives of animals and their human companions.
She grew up in northern NJ with two horses,
a dog and a cat, all of whom were crucial to her understanding of
just how important the human-animal bond can be. When
she is not busy at work loving everyone else's pets, she enjoys
spending time with her husband and their three kitty-sons: Hossifer
Jones, Apache, and Sky Jr. She is also a musician, and can be seen
playing around town with her band The Party Faithful.

 

Agnieszka Medina Sanchez, Veterinary Technician, graduated from the August
Cieszkowski Memorial Poznan Agricultural
University at Poznan, Poland in 2004, with
Master's and Engineer degrees in Animal
Science and Animal Breeding.
Agnieszka came from Poland and before coming
to the United States she worked as a veterinary
technician with large animals for four years.
Recently, Agnieszka graduated from Cedar Valley
College with A.S. degree in Veterinary Technology.
Her professional interests include Surgery, Dentistry,
Radiology, and Emergency Medicine.
In her free time she enjoys good books, movies, cooking, and a very
long walks around NYC with her husband.

 

Ginger Hughes is our practice manager.
She grew up in Rockland county, so nature and
the outdoors were always a big part of her life. She started working at a veterinary clinic when
she was still in High School and hasn’t looked back. Here at Northside, her special interests include nutrition, alternative medicine and
client education. Ginger is also an avid runner, occasionally boxes at the gym and is quite the chef! She lives in Queens with her husband John and their son Cameron.

 

Diana Viteri, Technician, is our special
"cat whisperer". Her touch seems to calm down
even the most agitated felines.
( We are convinced that Diana was a cat in a
past life). In this life, she is a veterinary
assistant at Northside, having one year to go in
the Mercy College Vet Tech Program. Diana has
an associates degree in Liberal Arts from BMCC
and an B. S. in business management from
Dowling College. She has done lots of cat rescues
and has worked hard to find homes for all of them.
She was a volunteer and a veterinary assistant for years at the
North Shore Animal League as well as other animal hospitals.
She brings a wealth of experience to Northside Veterinary Clinic and
we are lucky to have her on board. Diana speaks Spanish fluently,
shoots pool and practices Ninjitsu in her spare time.
When she is not nurturing a sick kitty back to health, you can find Diana
having a cookie on her break time.
