Can you recommend a urologic oncologist in Portland, Oregon?

Hi, I'm currently being treated by a generalist urologist for bladder cancer but would like to switch to a urologic oncologist. Does anyone know a good urologic oncologist in Portland, Oregon? Preferably at OHSU, which is easily accessible to me. And do you know how long the wait is to see that person?

Also, am I right that a urologic oncologist is a better option than a urologist?

Thanks!
