Provider did not seem prepared for my follow up. She was unaware of my medications and problem list, for which she has been following me. I do not feel like she reviewed my chart before coming into the visit.

I have problems with wax buildup in my ears. Other doctors will see the wax but don't say anything. I get vertigo that's when I know wax is bad. Dr. Grace is the only doctor that will acknowledge the wax is there and needs cleaned out.
