About me

I grew up in New Mexico, and I have wanted to be a doctor since I can remember. I attended medical school in Arizona and then discovered Portland, Oregon during my internal medicine residency, after which I never wanted to leave the Northwest again. After training in Iowa for allergy and immunology, I couldn't wait to return to Oregon to begin my practice. My family and I love taking advantage of all the beautiful Northwest has to offer. I have two sons and a wife with whom I love to explore the mountains fishing, skiing, and riding bikes.

About my practice

Although I am currently practicing Internal Medicine with Kaiser Permanente, my passion in terms of patient care is Allergy and Immunology. I enjoy educating my patients about their disease and allowing them to actively participate in deciding the treatment approach. I expect my patients to take an active role in their health, and I enjoy the process of partnering with my patients in their treatment.

How I thrive

My boys keep me thriving by keeping me young at heart. Exploring the outdoors with them and seeing the world through their perspective keeps me grounded in the midst of a busy life.
