    The doctors are top notch. I've been seeing PA Bethany and my wife has been seeing Dr. Koester for…read moreyears. Bethany has done several procedures on my face and does incredible work. My problem is with the billing dept. My wife has needed an allergy shot every month for the last year. Before starting we were told that they could administer the shots there or we could probably do it ourselves if we felt confident doing so, and if they did it it would only be a minimal amount. That turned out not to be the case, as the doctor pointed out fine print in the RX that it needed to be done in a medical setting. That was fine until the first bill. We were charged $52 for 5 minutes of a nurses time. That is more than the co-pay to see the doctor for a visit. After some talking an arrangement was made to charge ONLY $30. But every time I have to argue with billing to remind them of that arrangement. This time my wife went alone and was charged $80, 30 for the nurse and 50 for a co-pay. And she never saw the doctor. Sadly, that is the last straw and we are through with this office. Is money needed so badly that the billing department has to rake patients over the coals to squeeze every possible dollar from them?

    I saw Dr Weingartner and he was super professional and very friendly! He seemed to be very…read moreknowledgeable and put my worries and concerns to rest!! He even took the time to chat with my husband and "play" with our 4 month old!! Highly recommend him!!!! My appointment was very fast though we weren't rushed and I didn't wait more than a few minutes!!!! We found our new dermatologist!!!
