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.

I can't express my gratitude to Dr. Janus. My daughter now sees her as well and she is now on her way to a better quality of life due to Dr. Janus. Dr. Janus will politely tell me what I NEED to hear not what I want to hear. This is a fine line and balance of verbal skills and emotional intelligence. Dr. Janus is effective with me because she is skilled at this in addition to her many other attributes, experience and skill. I'm thankful to her.
