We are committed to sharing our experience with our patients and their families to help navigate what we understand is sometimes confusing material or circumstances. We provide a personalized education for families to ensure they understand their child's condition, results, and solution options now and for the future.



Every child is guaranteed to be seen at every visit only by a Board Certified Pediatric Pulmonologist with 10 years of post-graduate education. We strive to create a trusting relationship with every patient and parent, to enable a comfortable working partnership in health care decisions.



We are proud to be as available to every patient as possible. Through our Outreach Clinics, where Dr. Neddenriep and her staff travel to meet existing patients hours away, our 24/7 physician call, and our EHR portal, which gives patients access to results, documents, and more, we are able to connect with more patients more often.
