About Me

My goal as a physician is to use my expertise and creativity to find the explanation for the problem that brings a patient to see me. This is only one side of the equation though: just as important is using conversation, empathy and a spirit of partnership to understand a patient's life and values, so that we can craft a plan–together–to help them live their best possible life.

- Joaquin Chapa, MD

Breathing is an incredibly complex process that sustains us every minute of every day. Dr. Chapa believes that the problems of the respiratory system are fascinating to solve, but also gratifying to help patients with, because breathing well is so fundamental to living well. 

Before his career as a physician, Dr. Chapa was a professional runner and has experience pushing his body to the limits while also dealing with asthma. He believes that combining an expert understanding of the medical science and physiology of breathing with that direct life experience helps set him apart as a physician. 


Other Interests: 

Dr. Chapa has called Oregon home for his entire life; he thinks there is nowhere more special. Dr. Chapa deeply enjoys helping people in this community that he has always been a part of and where he has a lifetime bond. 

Outside of work, Dr. Chapa enjoys cooking, gardening, reading, trail running and traveling.
