“I am a new patient to Dr. Mahan ...”

I am a new patient to Dr. Mahan after my previous PCP retired. Dr. Mahan has been absolutely amazing. She listens and asks the right questions, she is incredibly knowledgeable and incredibly compassionate and strong. She has taken time to get to know me, my history as well as my family members when they have seen her too. By far, she is the best doctor I have ever had.
