    Dr. Merrill is the best dermatologist I've ever worked with. I've had skin issues for decades now and used to see the supposedly best dermatologist in San Francisco but Dr. Merrill is friendly, knowledgeable and proactive. I really appreciate the time he takes to discuss my skin issues.

    Dr. Merrill was an excellent practicioner. He listened well, but asked good questions to jog my memory. He explained all options carefully and kept me fully involved in the decision making process. He gave me confidence that we have some new options to try in the face of recent worsening of my symptoms. It was an excellent visit.

    I have been seen by over a dozen different dermatologist over the years and Dr Merrill is absolutely the best dermatologist I have ever seen. He's actually curious about what I have wrong with my skin and he's been trying to find the best medication to make it better too. I'm extremely impressed with his ability to diagnose my skin problems and then find a treatment too.
