    Parking is horrendous and needs to be improved...also 2 parking attendants are needed at founders and east buildings. Traffic gets backed up when there is only 1 attendant.

    Yeah, this experience up there was not enjoyable. My appointment was at 10:15 and it was 11:30 by the time I got out there. And I've probably seen the doctor a whole two minutes in that time. The receptionists don't know what they're doing. It's the most dysfunctional part of the whole clinic. Goodbye.

    While I know this is somewhat out of your control (Medicare requirements) I appreciate the fact that when I raised the question about a virtual visit I was able to get one for the future. I see no need to travel 45 minutes one way for a 15 minute visit when everything is and has been stable.

    Wonderful doctor. He is the only doctor that gave me further information about my sleep and some insomnia. Great information. I would see him again. It's such a blessing to have a doctor care and not a pull pusher like so many. Thank you.

    Provider started out fine but when I tried to pose questions 3 times the provider interrupted me before I finished asking a question. Must have had a bad day as I've not experienced that with others. First time meeting this provider. I wasn't impressed.

    My chart does not work the way it use to. I believe it may have changed when it switched to Emplify Health. When I am in the app and on an appointment it gives you an option to add the appointment to my calendar. The appointment adds to the day but no longer does it add to the correct time. If the appointment is for 2 pm it should add it to 2pm. Instead it adds the appointment as an all day event Instead of a time specific.

    The doctor was great! The two receptionists at check in were gossiping and complaining about their receptionist colleagues and supervisor the ENTIRE time I waited, which was over 30 minutes I length. I found this very unprofessional, unpleasant, and uncomfortable. This is not common in other departments I have been to in Gundersen.
