Reviews
Dr. Thyssen is amazing. I trust him completely. He is very thorough, personable, compassionate, and interested in your well-being. His staff is very efficient and caring.
Everyone is so nice, you feel like your grandpa is treating you.I would recommend to all my friends and family.
First visit with Dr Thyssen after many years with another doctor at SIG. I was very pleased with his thoroughness and style and look forward to future dealings with him!
I love Dr Thyssen! My whole family sees him… we have total trust in his whole team.
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.
Dr Thysen is a great listener and together we work out a strategy for managing my health issues.
I LOVE Dr. Erik P Thyssen at Advanced Endoscopy Center. He has done my three colonoscopies/endoscopies. I send all Friends and Family to Advanced Endoscopy Center for colonoscopies, endoscopies and very great Gastroenterology care. Thank you ALL.
Caring professional staff always attentive to my needs.
Best GI doctor ever. Saved my life several times and keeps me going strong.

It could not have been better, Amy inserted the IV and I did not feel a thing. Doctor Thyssen remembered me from 5 years ago, or he made it feel that way, very open and answered any question PLUS stopped by when I awoke. Got a call on Friday asking how I was. Drop the prep am I’m there each week. Thanks
Appt. Was to discuss and assess NAFLD. Dr. Thyssen is a very competent doctor, expert in his field. He explains everything calmly, honestly and thoroughly. His bedside manner is better than about 75% of the doctors I have seen over the years. I am confident in his ability to address my situation!
Staff and Doctor were all great at keeping me informed and were very detailed regarding medical history prior to my procedures. Was keep very comfortable, both physically and mentally regarding all aspects during the treatment.
Dr. Thyssen is the first GI I've had who actually took the time to listen to me and make feel heard. He took the time to talk with me, go over my 15 years worth of records, and create a treatment plan. I would 10/10 recommend him for anyone seeking a GI doctor who cares!
Excellent care and service from start
To finish. Great bedside manner and explanation of everything. Willing to answer any question and put his patients mind at ease

I see Dr. Thyssen and he is certifiably the best and most thorough gastroenterologist I have ever seen. I don’t ever feel rushed, he answers all my questions, explains my medical problems, plus he is a very compassionate doctor. I wish other doctors were more like this top doc.
Very professional. Great staff. As a retired medical professional I am critical of patient treatment. The staff is efficient and friendly. I felt as if I was safe. Excellent!
I have never had a bad experience here .Everyone is so nice and helpful.
Absolutely love the professional approach he has.. outstanding mannerisms, well spoken and very informative, and intelligent in his field..
