My name is José Guillen, and I’m a Family Medicine PA/MPH recently transplanted from California. My philosophy of care focuses on the collaboration between patients and providers, as I firmly believe in taking a team approach to resolve issues. I’m also keen on patient education, so if you have a burning medical question, don’t be shy. In terms of specialties, I’m an experienced provider for LGTBQ population, and have a dedicated interest in Travel Medicine.

I’ve previously worked in a variety of settings, from rural family practices in California to tiny clinics in South Africa and Nicaragua. I’ve helped out patients of all ages, from toddlers to elders.

In the beforetimes, I taught and created curriculum for Trackers, here in Portland, taught English and hip hop dance in Japan, and sold vacuum cleaners door to door on the streets of Texas.

In my free time, I cycle, play boardgames, and eat possibly unhealthy amounts of burritos in search of the Best Burrito Joint in Portland.
