      Dr Janus is the best primary care physician I have ever had. During this particular visit, she noted an anomalous condition, took the time to do in-office testing to confirm, prescribed meds and personally walked me to the scheduling people to set up an immediate specialist referral - despite her busy schedule. She also took the time to explain details of my condition, what it meant, and treatments. I specifically appreciate her concern, truthfulness, and time she spent to make me feel better about it.
