    Dr Blumenthal has been my Primary care physician for several years. She is always thoughtful and very attentive to my input and concerns, and is very clear about ongoing medications and next steps.

    This provider never seems to take my concerns seriously. I have needed to see specialists in order to have tests ordered that show serious ailments - these could have been ordered or investigated by a PCP if she took me seriously. She also barely did a physical (touched me) when it is my annual exam. [redacted]
