My provider squeezed me in as I felt I needed to talk to her very soon. She answered questions I had about new medications recommended and past medical events that I didn’t understand. As usual, I left the office feeling more confident about my health.

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.

Dr Thyssen is amazing! I came back from European trip Sunday night very sick and she saw me Monday am. Ordered meds, tests, and messaged me to see how I was doing. Called me to come in for recheck on Wed am and has followed up with me multiple times. Ordered stat CD and called radiologist personally to explain situation. Has messaged me explanations numerous times this week. She is so thorough and compassionate and caring, I have never had such an awesome doctor!!
