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. He advocates for the whole well-being of patients with care for their psychological as well as physical health. And Dr. Olsen was doing this long before it became a standard of care.

We had a great first appointment with Dr. Olsen. From the receptionists and the rest of the healthcare staff, we thought everyone was friendly, patient, and helpful. Dr. Olsen was really thorough and our boys really felt comfortable with him. We found the practice through other online reviews and the reviews were accurate!

We’ve been enjoying our visit with this doctor. She doesn’t rush you and takes the time to listen to all concerns. She treated both my kids with kindness and respect. Our toddler enjoyed her and so is our newborn. We will continue to see her. I’m glad we are able to get appointments something my old practice didn’t do. Overall it’s been positive so far and I hope it continues that way.

Dr.Olsen is the best pediatrician! He makes my 10year old son feel so comfortable, he tells jokes & makes the visit so fun but he also listens to all concerns too. Dr.Olsen/the office makes a point of being on time with the appointments, we are never kept waiting for the Dr. We never feel rushed and the practice does a wonderful job of communicating too. The nurses are exceptional- Carrie, MaryBeth, Mary, Mindy are very friendly & knowledgeable. I highly recommend Millennium Pediatrics.

I like that Doctor Dawn doesn't leave the room, till all the concerns are addressed, and she always encourages to call if any symptoms get worse. The nurse practitioner are very helpful super thanks to them. After putting message on answering machine for help, nurse practitioner will always call back and will provide necessary guidance.
