I used to go to Dr. illo off of 72nd in Tigard. He is awesome and has a masseuse work on you before every appt. Not sure if he works with a lot of pregnant ladies though but I would imagine he does. I will warn you when I used to go he would often be running an hour late for appointments by the afternoon. Hopefully he's done something to fix this.
