Welcome to the Fishkill office of CMG.

Our doctors have been caring for children from Fishkill to Wappingers Falls, from Beacon to Poughkeepsie and many other communities in Southern Dutchess and Orange and Ulster Counties for over 15 years. We provide a small office environment where you get to know your doctors, while having all of the resources of a large pediatric practice. We focus on all aspects of health care for children, from infants through 21 years of age. We would love to be part of your family; come and be part of ours.

Your Fishkill Pediatricians:

You might call Dr. Marc Habert a fresh-air freak – and he encourages his patients and their families to be the same. In fact, early in the morning, before the office opens, you’ll find Dr. Habert out rowing on the Hudson River. Dr. Habert is interested in all aspects of pediatric health care, including breastfeeding, developmental pediatrics, infections diseases, and asthma. Most of all, he likes being able offer his patients and their families ideas for fun, healthy outdoor activities.

Dr. Natasha Tzagoloff joined The Children’s Medical Group in 2012, and immediately began winning over patients and staff with her warm personality and smile. Dr. Tzagoloff grew up in the Upper East Side of Manhattan, did her undergraduate work at Barnard College, and earned her medical degree at Downstate Medical Center. Located in central Brooklyn, Downstate is the only academic medical center for health education, research, and patient care serving Brooklyn’s 2.5 million residents.

Dr. Tatyana Shkolnikov is a board-certified pediatrician who joined the Children’s Medical Group in 2023. After she graduated from Smolensk State Medical University in Russia, she worked as a general pediatrician and neonatologist prior to becoming the Director of the Neonatology Department in the Regional Children’s Hospital. She also participated in an international research program conducted by the International Atomic Energy Agency and St. Petersburg Research Medical Center regarding the Chernobyl disaster, resulting in two publications in the IAEA Bulletin.

In 1994, Dr. Shkolnikov moved to the US and completed her residency at Brookdale University Hospital in New York and Fellowship Program at Winthrop University Hospital in Mineola, NY. After completing her training, she joined the Pediatric Emergency Department at Montefiore Medical Center in Bronx, NY until 2009 when she joined Carmel Pediatrics in Putnam County (which soon became part of BCHP). She is also a Fellow of the American Academy of Pediatrics and a Clinical Assistant Professor of Pediatrics at New York Medical College.
