    About our process

    Dr more than doubled the time for treatment than what I was originally told with no reasonable explanation for the delay. Cardiologist has shown no interest or concern in my heart condition so everyone else who holds me hostage needs to defer to the Cardiologist. If Cardiologist is not concerned then other parties can back off a bit.

    I found Dr. Soriano impatient more than anything. He failed to identify my condition (hernia) and failed to offer me an explanation of the mammogram picture until I asked. Even then it was only a half hearted effort. Then Dr. Soriano proceeded to get irritable with his insistence that I lose weight first before the surgery. I had to actually calm him down to explain my options. I had to tell him to relax and explain my options. He did not explain all of my options for weight loss like the weight management clinic. I had to ask about this. His explanation of the surgery indicates that he never read my file in any detail. Because I have had 2 major surgeries I have a general Idea of general anesthesia. If he had looked he would have noticed that I had general anesthesia twice before.
