UI lost my amazing Dr. Dembitsky and had to research for a new Dr. I heard great things about Dr. ,Gheissari, so this was my first visit with her. She was very thorough and took good notes. She listened well and updated my chart reviewing all upcoming needed procedures or shots. I know it takes a few visits to build a rapport with a new Dr and I have confidence she is a good fit for me.

I've had two experiences at Sharp recently with exceptional care! Comparatively, Dr. G falls extremely short. This is my second appointment. I thought perhaps she was overly busy upon my first meeting; we all get busy.Unfortunately, it was the same experience on my 2nd appointment. By no means did I feel Dr. G was engaged, caring, or collaborative. At one point she actually laughed at one of my questions and dismissed it by answering me In such a derogatory tone. I was dumbfounded. Any information gleaned from the appointment was the result of me pressing and asking questions and repeatedly pressing for clarification. Zero attempt to communicate beyond the basic as she rushed out the door. What a disappointment! The past two physicians were above and beyond in every respect. Exceptional professionalism, attention to detail, and just an overall feeling of respect and kindness. It was noteworthy. I am not in the habit of writing a negative review, however the experience was disappointing enough to do so. It takes months to get an appointment. Rearranging work schedules, driving to an appointment, paying copays, and primarily seeking medical advice and direction. Quite discouraging!!
