Took time to explain everything very well (I appreciated him explaining to me the things that could potentially be causing my issues and why were testing what we were- he kind of walked through his problem-solving process with me instead of just explaining diagnosis at the end), addressed my concerns, and was really good at communicating. Incredible doctor!
