Welcome to Unionville Pediatrics, you’ve come to the right place. 

We have been caring for children of all ages since 1977 and it gives us great joy to watch young people grow before our eyes. Many of our former patients are now parents and being responsible for generations of healthy families is something that we’re most proud of. 

Our practice was started by Dr. S. Russell Sylvester and Dr. Frederick V. O’Connor and is currently managed by Dr. Peter Jannuzzi and Dr. Mark Gilroy who oversee a group of six physicians, two nurses, and a highly skilled office support staff. Our main office is located at 101 Main Street in Unionville and our Acute Care Center (ACC) is located at 1027 Farmington Avenue in Farmington. 

One of the biggest differences between Unionville Pediatrics and other pediatrics offices is that we have two completely separate locations for sick and well care. Routine checkups, vaccinations, and mental health screenings take place at the Main Office and sick appointments are taken at the Acute Care Center. We do this to ensure that contagious illness does not get spread to healthy patients and to offer easy-to-book, same-day appointments for those who need it. Our groundbreaking approach to patient-center care has been recognized locally by publications including the Hartford Courant and nationally by the American Academy of Pediatrics.

We are proud of the reputation we have built over nearly 50 years in the Farmington Valley area. We are an independent private practice which allows us to practice medicine the way we see fit without being beholden to a more corporate style of health care. Our traditional style of patient-facing care blends seamlessly with the modern medical techniques that we use every day, offering what we believe to be the best possible approach to pediatrics. 

Our friendly staff emphasizes availability and has perfected the balance of spending enough time with our clients without making people wait too long to be seen. We are there when you need us, including after hours and holidays when you can always reach one of our doctors on call.

Each of our six physicians is board certified/board eligible and we have a truly special mix of seasoned veterans and young talent to offer a broad level of expertise and experience. We are also certified by the National Center for Quality Assurance (NCQA) as a Patient Centered Medical Home. This is a rigorous test of measures that offers complete assurance that our patients come first. 

Lastly, we participate in virtually all insurance plans and we are always accepting new patients. We look forward to meeting your family.
