Great medical team and facility. My appointment was on a rainy day and the 5 minutes of "fireplace time" was a nice prelude to my visit.
Staff and Dr. Thyssen were top notch.
Final thoughts are "Village-Kitchen-Baby".

Dr. Thyssen is the best Dr. I have ever visited. She really listens, discusses options and I always leave more informed and with a plan for the future. If my situation warrants a referral or follow up with another Dr., she follows through quickly and keeps me informed. She cares and it shows.
