It was apparent the Doctor reviewed my Chart prior to the appointment.I am a hard stick and the lady that drew my blood only had to stick me one time..Dr Ninaber is a great Primary Care Physician and I hope he never leaves Providence but if he does and he remains in Los Angeles I would continue to have him as my Physician even if I had to pay cash.to see him.
