Our office is pleased and privileged to care for your infants, children and young adults.

What started as a solo practice to serve the Noroton area over forty years ago by our founding partner, Dr. Michael Suchenski, has grown to a group practice seeing patients from Darien and the surrounding communities.

Our three Board Certified physicians pride themselves on being an independent Pediatric group practice in one location. This setting allows us to provide comprehensive and personalized care to all of our patients from birth to young adulthood, and we are available to you both during and after office hours.

Our office is conveniently located immediately off Exit 10 on I-95.
