Dr Watanabe and his team including Melissa is absolutely fantastic. Dr W is a complete doctor that cover all the bases, asks great questions, allows patients to ask all questions without feeling rushed and then always has a coherent plan Truly a gem of a doctor taking care of me as a doctor as well.
