Are you looking for allopathic (traditional western MD) or naturopathic/alternative? Also, are you looking mainly for a primary care physician who is understand, or a specific sports medicine/orthopaedist? What part of the metro area?

Many of the traditional docs I've met here are quite active; cycling, running, and triathlons seem to be a very common hobby for MDs here in Portland. My own doctor is not a cyclist herself, but she referred me to a local PT clinic in my neighborhood and I had at least one sport in common with virtually all of the therapists that worked there.

Two standout recommendations that I can make are:

A good holistic clinic for sports medicine is the Back in Motion practice. They are mainly chiropractic/naturopathic.

For women's health, Portland is home to the clinic founded and run by Dr. Tori Hudson herself, A Woman's Time.
