I had an excellent experience. As opposed to just about every other health care provider I have, it was completely unhurried. The doctor had plenty of time for a long conversation about my health and I was able to go much deeper into topics than I would have imagined. He walked me through each of my test results in depth. I walked away with a much better understanding of my health and how to manage it, not just addressing immediate problems.
