Welcome to the Highland office of CMG.
Our doctors have been caring for children from Modena to New Paltz, from Highland to Gardiner and many other communities in Ulster County for 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.
