Family care the way it should be.

Our parents are our former patients for a reason. At Unionville Pediatrics, we offer a boutique practice guided by principles, not corporate governance. With two offices to provide separate well and sick care, you can be sure your child will be seen in a safe environment by the best practitioners in the field.

  • "I've had great experiences here and we love Dr Jannuzzi and the rest of the staff."

    Elizabeth Manuele

  • "Huge shout out to Unionville Pediatrics for enrolling my son, scheduling him for his next check up, and we were also able to be seen today because my son isn’t feeling well! This was all done in under an hour of speaking with them for the first time."

    Christine Cormier

  • "The doctors and office staff are always positive and friendly. I have no problem getting appointments and the wait time is always short. I called after hours on a holiday weekend and the doctor came into the office to meet us and treat my daughter. I highly recommend this office!"

    Kerri Kazlauskase

  • “I have used both Doctors Jannuzzi and O'Connor for the past 14 years. I have found them both to be exemplary doctors. I have never trusted any doctors as implicitly as I trust them! Over many years they have been consistent in the quality of care of my son. They are also easy to get a hold of, and I have found their response time to be remarkably impressive!”

    Amy Eisner

  • "I think the doctors and staff are the best in the business. My sons were very fortunate to have them for their physicians for most of their childhood. The only draw back is that the boys had to grow up and move on."
