    Provider is wonderful and knowledgeable. But always running very late. But gives you all the time you need to talk with him and understand your issues.

  • Jul 21, 2018

    After years of struggling, Dr Purnell was able to diagnose my condition almost upon seeing me. This is rare, though it is not rate at OHSU, hands down the best medical care I've ever had has been from the doctors at OHSU.

  • Mar 19, 2018

    Dr. Purnell is a very good kind hearted physician and I appreciate that in a dr.

  • Mar 14, 2018

    Dr Purnell is simply the best. If he weren't available to manage the rare diseases I'd have, I'd have to fly to Tucson AZ for treatment. No one in Seattle could help me.

  • Feb 02, 2018

    This was my first visit with Dr. Purnell and I needed some diagnostic labs and test for future treatment options and goals.

  • Jan 11, 2018

    my regular doctor would always tell me "I don't know, go see a specialist" so I did and he was able to look at my chart and tell me exactly what was going on. I wish the OHSU Richmond clinic was like this

  • Jan 02, 2018

    Dr. Purnell is outstanding. He has gone out of his way to help me get what I need. He is professional, kind, patient, understanding and obviously very well trained. I highly recommend him.

  • Nov 15, 2017

    Dr. Purnell is actually above a very good score...seriously

  • Aug 31, 2017

    I know that Dr. Purnell has a lot of patients but he clearly takes the time to refresh himself on cases before meeting with patients because he easily recalls past conversations and issues or past questions that came up in previous visits and remembers to follow up. I feel very fortunate to have found him.

  • Aug 24, 2017

    Dr. Purnell is very calm and personable. He explains things fully, and seems very interested in serving his patients.
