By far the worst doctor I have ever had. Went in to talk about medical assisted weight loss. Got yelled at told I was starving my body. Which is completely incorrect when I try to eat 1400-1600 calories a day and am 5’4 and rarely work out. I asked her what amount of calories then should I consume to loose weight and she told me she didn’t know but it’s not the numbers I have been using. When asked if I worked out I said I ride a stationary bike sometimes at about 11-13 mph which is a slow riding pace. The she yelled at me again screaming I’m over working my body. I asked her to stop yelling and she said.”oh I see how this is gonna be.” On a previous visit she wanted to do a Brest exam so she just took it upon herself to take my clothes off. No I didn’t give permission or ask for assistance! She’s an absolute incapable NUT CASE! RUN
