Our Providers

Tiana Won MD, FAAP

Being a pediatrician is an honor and a joy. I love joining families in celebrating the wonder that surrounds a new life, each milestone gained, and the growth that comes over the years. I also recognize that raising children is often not an easy endeavor and aim to provide the best care possible as we walk through challenging times together in pursuit of a healthy future for our community’s younger generations. As a pediatrician I seek to listen well to the families I serve so I can advocate for their best interests, within and beyond the walls of the clinic.


Dr. Won knew she wanted to work with kids and families before she knew she wanted to be a pediatrician. She first considered pediatrics when her younger brother was sick and she wanted to understand what was causing his illness, as well as see him get better. After exploring various related fields through internships and volunteering experiences during her undergraduate education at the University of Texas at Austin, Dr. Won spent time shadowing her former pediatrician, which confirmed her desire to study medicine. She earned her medical degree from Baylor College of Medicine in Houston, Texas before moving to the Pacific Northwest to complete her pediatric residency at the University of Washington in Seattle. After her year as chief resident with the University of Washington, Dr. Won moved to Australia to experience a different system of practice in her husband’s homeland before returning to the Pacific Northwest. Dr. Won is board-certified and practices in our Tigard and Beaverton offices. 

Culinary Apprentice

Dr. Won enjoys the creative process of cooking and baking, especially when she can share the end product with friends and family. While she is no expert, she enjoys continuing to learn new techniques and recipes from her mom, Ottolenghi and the NYT cooking team. 


Dr. Won believes in being quick to listen and slow to speak. She values people’s stories and recognizes that we have much to learn from each other. Storycorps is one of her favorite podcasts and she has also found their toolkit helpful for recording some good memories with her family members. She knows she must first listen to children and families before she can advocate for them and hear from learners/mentees before being able to teach them.  


Dr. Won’s family has taught her much over the years and she still learns from them today. Her mother continues to be a model of generosity in her life. Hearing about her father’s journey as an immigrant from South Korea to the US opened her eyes to some of the challenges many of our neighbors face. Her “little” brother is about 8 inches taller than her and a much better chef; he and his wife have also made Dr. Won an aunt to their rescued goldendoodle. Though she doesn’t usually consider herself competitive, her husband has helped her realize she enjoys a bit of healthy competition in the realms of running, badminton, and hula hooping.

Fun Facts

Dr. Won has been exposed to a variety of different medical systems through her internship in South Korea at one of the World Health Organization’s East-West Collaborating Centres, her years volunteering at a clinic for the uninsured in Austin, and her work at a children’s hospital in Australia. Her curiosity about different systems of practice has given her a wider lens through which to look at our current models of care. She and her husband enjoy the outdoor opportunities around Portland and particularly love to be near the water- whether running by the river, hiking along the coast, or stand up paddle boarding. They also enjoy swing dancing, climbing, and treating themselves to delicious baked goods after any of the above activities. Dr. Won appreciates the family culture of PANW, the focus on community, and the flexibility to improve so we can better care for our patients and families.
