        My visit was fine

        Usually I’ve had to wait so much longer to be seen, but yesterday’s visit I was seen in a timely manner.

        Good as always, but..

        Dr Cowan is a smart, capable, and normally very engaged doctor,but I think he was under the weather during.the visit. We fully trust him as our doctor.

        I had a good visit with Dr Cowan

        It a fan of your app, wait time in the lobby went beyond appointment time. The testing process went well, and time with the doctor was good.
