I found Katherine Sandbach, PA to be dismissive and vacant during my visit. Within 10mins she asked me the same question "have I had a significant sickness, flu/etc in the past 4 months". She acted as though I was not being truthful and tried ending the apt after she dismissed a lesion on my chin that hasn't healed in a month as a "burn". I am 37yo I know what burns are and how they heal. She then referred me to a dermatologist who doesn't take my insurance. After basically nothing was resolved during my visit the next day when the blood work came back normal they could offer nothing more that the typical "we don't know why" and I had to ask them for next steps. I would not recommend Katherine Sandbach, PA. I did however enjoy the staff and another Dr. who came in for a moment and actually explained things to me that made sense and with one look in my ear diagnosed a receding ear drum and the symptoms it causes. Katherine had already looked in the ear and said nothing of the sort.
