Our Providers

Jay S. Rosenbloom MD, PhD, FAAP

Being a pediatrician to me is all about teaching. The best thing I can do is help a family understand why we ask the questions we do, or what we are looking for when we check a body part. This empowers them and helps them to understand the recommendation we make for treatment. In this process, parents and children grow in their ability and in their confidence, helping them make well-informed medical decisions that are right for them.


Dr. Rosenbloom was a science nerd from the beginning. He wanted to be an entomologist (someone who studies bugs) when he was little. He wanted to take apart all of his family’s appliances to learn how they worked (fortunately his parents didn’t let him do that too often because he had no interest in learning how to put them back together). Dr. Rosenbloom attended Lewis and Clark College where he earned his B.S. degree (favorite class of all time was about algae). It took two years working in a cancer research lab to decide whether he wanted to pursue a career in medicine or scientific research.  Still indecisive, Dr. Rosenbloom went into medical and graduate school at the same time. He earned his medical degree and a PhD (in molecular biology) from OHSU. In the clinical years of medical school, he realized that working with kids was the best job ever. He spent 3 years at the University of Arizona for his pediatric residency and then joined Pediatric Associates of the Northwest. Dr. Rosenbloom is board-certified and practices in our Tigard office.


For many years, Dr. Rosenbloom has worked with different groups to advocate for children’s health concerns. He worked with the state on their childhood immunization collaborative and helped pass legislation on that topic. He is currently the medical director for the Children’s Health Foundation (and Alliance), where he works with pediatricians in different medical groups to help improve the care for children across the region.  Dr. Rosenbloom is also one of the contributors and presenters for Boost Oregon, a group that is dedicated to vaccine education.

Avid learner

Dr. Rosenbloom loves to learn from his patients and their parents, and not just about medical issues. Every child has their own passions and has something they can teach, and he believes we just have to remember to take the time to listen.


Dr. Rosenbloom is a third generation Portlander. No matter where he has traveled, he has always wanted to make Portland his home. He grew up with two sisters and now has three daughters (girls?!). They are each so different. It is with his children that he has been humbled many times, learning that the advice he gives as a doctor isn’t always as easy to implement as it might seem.

Fun Facts

Dr. Rosenbloom’s favorite hike is Tamanwas Falls on Mt. Hood. He loves spicy food (Thai, Indian, Ethiopian, etc.) and eats all left-overs cold. He will often eat combinations that normal people think are strange. In medical school, he learned to knit. His first project was a sweater for himself. It wasn’t bad for a first project, but don’t expect to ever see him in public wearing it. He has been on medical mission trips to Haiti, Bolivia, and Kenya. Dr. Rosenbloom is the caretaker for our tropical aquariums in the Tigard office. He loves being a part of PANW because providers work to stay current in medical treatments and are always learning from one another. He also get stickers when he is well behaved!
