This was a new patient appt. with this Dr. so my responses are based on only 1 experience. Appointment felt a bit rushed. Would have liked to have had a little more time with her to go into my history and current issues in more detail but will have another opportunity in 3 mos. at my physical appt. (nothing was urgent). Overall, I think I will like having her as my new PCP. Her \'bedside manner\' was good (i.e., personal chemistry) and that is very important to me. I also appreciated that she had reviewed my previous labs \'PRIOR\' to entering the exam room to meet with me.
