Was there anything that you feel was outstanding?
Staff all had great and friendly attitudes. Dr Lehman was the most thorough and informative Dr that I have visited. Exactly what we want in a Dr. He showed great interest in making sure that I was ready for an upcoming surgery. He also reassessed her current heart health and adjusted some medication. I have great confidence in his ability to keep me healthy.
What could have been done to improve your experience?
Not much.

What could have been done to improve your experience?
Dr. Lehman contintually misgenders me. My chart states that I am a trans man. I have a beard and am visibly masculine, but he refers to me as "Miss [last name]" and she/her loudly as he takes verbal notes in my chart. It's very rude and unsettling.
