I left a previous doctor at NW because the PA did not listen to me. This experience was 1000x better. Congratulations.

Dr. Hristoff was very knowledgeable and informative. He, one of the only doctors that has done this, went through my previous tests and compared them to the most recent test results. He took his time and made sure I understood everything. I was very impressed.
