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!!
