I strongly recommend fully vaccinating kids against preventable diseases on the schedule approved by the Centers for Disease Control and Prevention (CDC), the Advisory Committee on Immunization Practices (ACIP), and the American Academy of Pediatrics (AAP). I do not support nonmedical vaccine exemptions.

Care Philosophy

I believe pediatric care is most effective when children, their parents, and pediatrician work together toward a common goal of good health. I encourage questions from parents and children and appreciate the opportunity to educate families about illnesses and treatment options. Together, we work through the challenges and joys of parenting. Whenever possible, my focus is on preventive health care, integrating my training in traditional evidence-based medicine with a more holistic approach to wellness."

Dr. Mooney was born and raised in St. Louis, Missouri. After completing her B.S. at the University of Notre Dame, she attended Washington University School of Medicine in St. Louis. She moved to the Pacific Northwest for her internship and residency at the University of Washington program at Seattle Children’s Hospital. After practicing general pediatrics for several years in the Seattle area, she began practicing in Portland in 2006. Throughout her career, she has been actively involved in medical quality improvement efforts, exploring ways in which pediatricians can improve the care they provide to families.

Dr. Mooney is married and loves being a mom to her two boys, Peter and William, who have managed to provide plenty of hands-on experience to complement her medical training. She also enjoys swimming, reading, music, and travel.


"Everyone at Metro Peds happy valley is amazing. But our favorite is Dr.Mooney. She has provided extraordinary care to over 20 of our kids and foster children for the past 10~years we have had multiple children with complex medical issues and I have always felt confident that she would be the one to trust with their care. She is knowledgeable, kind and compassionate. Even after we moved an hour away we still bring our more complex kiddos to Dr. Mooney. We know if she can’t help she has a wide range of professional relationships within the medical community of people who can. And she is always quick to refer if need be. If your looking for your families life long pediatrician definitely look no further. I honestly don’t know if we could have cared for all of these kids over the years without her help."

"I love this pediatrician office. My kids are always seen quickly and they do a great job of checking out my kids completely and follow up care. I highly recommend Dr. Mooney. She's so warm and compassionate. She also is a great doctor. One of my kids was having signs of appendicitis but the ER said she was fine. I took her to Dr Mooney who agreed with me that something wasn't right. She sent us to Randalls childrens hospital and within 8 hours of her original appointment with dr Mooney my daughter was having her appendix removed. Luckily it had not errupted as dr Mooney caught it in time. 24 hours later we were home and my child feels fine. Not even a scar! This is the kind of care every mother needs for her child."

"My family is very happy with metropolitan pediatrics. Friendly, professional, and helpful staff and amazing doctors. Both my boys see Dr. Mooney and she answers questions very thoroughly and never rushes through our appointments. The after hours advice line has been very helpful and the doctors and staff are great about answering emails on the myhealth portal. Definitely recommend!"
