I wish all of my doctors were like Dr. Zanger. My case was not complex, but there was a bit of information for her to review and assess before talking to me. I felt that she did her homework, and walked in prepared. (In other words, I did not feel she was trying to ‘speed-read’ my file after she walked in, so she could save time on her schedule.) In my case, I had three doctors who had recommended drugs in the past 60 days, and she laid out clearly my options and what points I should bring up to my primary care physician.

Dr. Zanger is an excellent doctor. Always returns calls and messages. Plus, she's keeping me alive. Anything better than that?
