How likely are you to recommend Dr. Mercado?

(Select your rating)
Dr Mercado was thorough in checking me. She took her time answering all my questions and didn't rush me. She showed me my test results and walked me through it so I can understand her explanation. She also tried to connect with me on a personal level which I appreciated. I was seen right away. I recommend Dr. Mercado.
