Our Providers

Mari Kay Evans-Smith MD, FAAP

I enjoy getting to know my patients as unique people, partnering with parents, and working together for the good of my patients. By actively listening to both patient and parent, I exercise my belief in a holistic approach, understanding the need to consider the emotional and psychological health of my patients, as well as the physical concerns.


Dr. Evans-Smith decided she wanted to become a physician in the 3rd grade. Her decision was solidified after a trip to a Haitian children’s hospital as a college student. She was encouraged and affirmed while working with a professor who became a mentor during a research experience at Oregon Health and Science University. She completed her medical degree at Loma Linda University, and her residency at University of California, Irvine. Dr. Evans-Smith is board-certified and practices in our Portland office.

Humanitarian and Traveler

Dr. Evans-Smith has paired her love of travel with her commitment to helping those in developing nations receive quality medical care by leading medical teams all over the world.  She has treated patients in Peru, El Salvador, Haiti, India, Malawi, and most recently Bolivia.

Healthy Lifestyle Enthusiast

Dr. Evans-Smith understands the challenges of trying to create a healthy lifestyle for your family and believes she can’t expect her patients to do what she can’t do herself. Cooking plant-based meals, spending time outdoors hiking and walking, meditating and practicing yoga are all important to her. She also loves to maintain social connections by regularly meeting a friend for coffee and hosting big family gatherings.


Married with two children of her own, Dr. Evans-Smith has experienced many challenging aspects of parenting firsthand, including parenting a strong-willed child, managing the sports injuries of an NCAA college athlete, navigating through grief, and finding balance as a working parent. As social media manager for PANW, she loves finding and creating relevant parenting resources to share with families.

Her favorite vacation spot is the house her grandpa built in Pacific City, Oregon. Her favorite food is chocolate and her favorite local hike is Cascade Head Trail on the Oregon Coast. She enjoys working at PANW because of the opportunity to help patients of a variety of ages, from newborn to young adults.
