I was referred to Dr Terhar MD for an abnormal mammogram!! I was a little uneasy going to a specialist. My first visit went so smoothly. Dr Terhar was so caring, explained everything that she was going to do. Explained my sisituation in detail, answering any question I may of had!!! She said she needed to do a biopsy and that she could do it that same day. Miracle, one less appointment to have to make and possibly a quicker answer for me. The not knowing is the hardest!!! Love my new Dr!!!!

Dr. Terhar left deep margin of DCIS in me after a lumpectomy. She lied to me about it. I went to her with a very early stage I. Told me tho she didn't meet required margin she was happy with what she got. 2 years later I lost my breast. I called her after mastectomy, asked her why she lied, her voice got VERY high pitched as she said "Oh yes, I'm very sorry about that," then screamed,"Your oncologist & radiologist should have told you, NOT ME!" My 2nd surgeon is furious with her! BEWARE!!!!
