We've been with Dr. Monsour for 5+ years now. She's very sweet and gentle with our kiddos, extremely knowledgeable and listens intently to any concerns we have had. We had our first visit with Dr. Olsen and had s similar experience. Millenium Pediatrics is an amazing practice! You will not be disappointed. The gentleman who works the front is also very helpful, courteous, and kind!

Dawn Mottlow is wonderful. We’ve had several visits with her, and every time she has been kind, attentive, and very thorough. She takes the time to listen, answer all of my questions, and makes me feel comfortable discussing any concerns about my baby. I really appreciate how caring and professional she is. We’re always happy when we get to see her. Highly recommend!

Dr Olsen is the best! We really enjoy well visits and find them informative and value that he respects our questions as parents (patients since 2019 when our first was born). His non-alarmist approach helps us feel grounded during all of the developmental stages. The nursing staff also takes the time to answer our son’s questions about how vaccines work etc without dumbing down answers. A very positive experience which has us looking forward to well-visits.

I cannot recommend Dr. Olsen enough! From the very first visit, we have felt completely heard, supported, and cared for. He takes the time to answer every question, explain things clearly, and genuinely know and care about our daughter as an individual—not just another patient. As a first-time parent, having a pediatrician we trust has given us so much peace of mind. The entire office is kind, responsive, professional, and always makes us feel comfortable reaching out when we have questions or concerns. We are so grateful to have found such an amazing pediatrician and would recommend them to any family looking for someone who truly cares about their patients!
