Welcome To Millennium Pediatrics

Dedicated to the health and care of infants, children, adolescents and young adults

Few things are more comforting to parents than finding a great pediatrician. At Millennium Pediatrics, a team of outstanding pediatric specialists fills that need for many families in and around Naperville, Illinois.

From newborn care through pediatric care and adolescent care, Millennium Pediatrics is here to ensure that kids receive the highest treatment standards as they move through the phases of childhood. Preventive health is a strong area of focus, including vaccines administered according to the latest guidance from health authorities.

The team at Millennium Pediatrics understands that a healthy childhood involves more than just physical health. Addressing issues like nutrition, sleep quality, school performance, social interactions, and extracurricular activities is an integral part of holistic pediatric care.

When issues arise, same-day sick visits strive to quickly determine the source of symptoms and get kids on a path toward relief. Families have access to behavioral health and mental health services in addition to common childhood concerns like asthma and allergies, dermatology issues, as well as sprains, strains, and other sports injuries.

Accessibility is an essential part of excellent pediatric care. An after-hours nurse line helps parents get guidance and support outside traditional office hours. Telehealth offers the chance for families to connect with their pediatrician without a trip to the office.

For parents in and around Naperville, Illinois, who are searching for pediatric care that encompasses all aspects of their child’s life, Millennium Pediatrics has a lot to offer. Schedule a visit online or by phone to meet the team.

Dr Olsen has always been such a strong parent advocate. Every appointment he shares his expertise but also leans hard into knowing that I, as Mom, know my kids the best. He listens, offers sound advice, and definitely feels part of our family team to keep our kids healthy and thriving. He is a wealth of knowledge for our little guy with Down Syndrome, which gives us an extra sense of comfort! His staff is incredibly “on it” and I always appreciate their follow-up calls and advice after sick visits. 10/10!

Dr. Olsen has been our pediatrician for almost 25 years now. He sets the bar for maintaining a practice that consistently puts children first.
