Dr Gainer is my PCP. He is the finest Dr I have ever had. He listens, thinks things through, and lets me make informed decisions. He is brilliant and I trust his judgement. I can't say that for any of your other physicians that I have seen with the exception of Dr Meyer in Dermatology. Thank you. Please give Dr Gainer a raise or a monetary award, Thank you.
