    Doctor Mercer is well educated

  • Aug 7, 2025

    Dr. Mercer is a fantastic provider. She is personable, engaged, informed and collaborative. I never feel rushed with her, and she takes the time to answer all of my questions, provide care options, explain the pros and cons of each care option, and provide additional sources of information. She encourages intellectual discourse without being pedantic, recognizing that some parents value an explanation of the research behind medical guidance. Dr. Mercer has been my son's pediatrician since his first medical appointment a few days after birth and I hope to remain with her for the rest of his childhood. She's an exemplary medical provider.

  • Jul 22, 2025

    One of the best, most thoughtful doctors I had. I wish she was a primary care provider for adults as well.
