Everything about my visit was professional kind competent patient and helpful. Dr. Thyssen is the best!!!
Everyone was so attentive and kind.
Contacted Advanced Endoscopy Center to make an appointment for my 10-year follow up colonoscopy. Dr. Steven Fern performed my prior colonoscopy procedures. Dr. Erik Thyssen attempted 1st Day and performed my most recent colonoscopy procedure on the 2nd Day due to my cleansing being incomplete on Day 1. From scheduling to Day 1 and Day 2 Receptionist (Donna) to Pre Op Staff (Day 1 Emily and Andrew) and Day 2 (Ki, Marissa and Jody), OR Staff (Day 1 ?) and Day 2 (Emily, Tabie, and Wit), Recovery Staff (Day 1 ?) and Day 2 (Paula) and Day 1 and Day 2 (Dr. Thyssen), the entire staff were all extremely friendly, professional, and communicated how to successfully complete the procedure. I continued my cleansing with additional materials provided by AEC and with nausea prescription from the pharmacy. The 2nd Day Procedure went extremely well, and in 10 years, I will schedule another appointment with Dr. Thyssen. Thank you for your excellent service.
Dr. Thyssen was terrific. Very helpful and am confident in his care going forward.
This clinic should boast about patients being top priority. All the staff are so helpful. Dr Thyssen is one of the best doctors I’ve ever seen. He takes the time to listen to you and will work with you to insure you are knowledgeable and comfortable with what needs to happen.
