Dr. Madsen was truly one of the worst doctors I've ever seen. [...] He was dismissive and unhelpful. [...] All of this took maybe 2 minutes and then after that he spent 10 minutes discussing medication that I could maybe one day take if my medication looses effectiveness (it is nowhere near that). I waited over an hour for someone to dismiss me, degrade his staff, and continue to waste my time. I will never see Dr. Madsen again and truly hope that this is not the standard you hold your doctors to.[...]
