What They Are Saying
From the moment I walked into his office, I felt heard, respected, and genuinely cared for. He took the time to listen to my complex medical history, asked thoughtful questions, and explained everything in a way that was easy to understand. He never made me feel rushed or dismissed — instead, I felt like I had a true partner in my care.
His knowledge, professionalism, and kindness stood out immediately. I left the appointment feeling more confident and hopeful than I’ve felt in a long time. If you’re looking for a GI doctor who actually takes the time to understand YOU as a person and not just a list of symptoms, Dr. Tocco is the one. Highly, highly recommend!
I usually see Nicolette VanMaldeghem in between visits with Dr. Bakken and she is excellent as well. I have nothing but good things to say about this practice.
From check in to recovery.
The prep wasn't fun, but once I was in the office it went very quickly. Every staff member was very very friendly. Even the call to check up on me after I was home.
Thank for a great experience from ALL
I would highly recommend
Thank you all so very much!
Allen Jefferson Ed.D, MS
The nurse and CRNA gathered more information and then the CRNA promptly wheeled me to the procedure room. Both the assistant and doctor were already there, ready and kind. The CRNA and assistant quickly got me all set up, and before I knew it, I was awake and ready to go.
A kind staff member even escorted me to my car afterward. Overall, it was a 5-star experience!
Dr. Weber was informative after the procedure and made us feel confident with the outcome. Mary, Dr. Weber's RN,
was super friendly and engaging; taking care not to rush us and answer any other questions we may have had. She has a wonderful "bedside manner".
The waiting area couches were quite comfortable also!
Thank you both for the positive experience at your facility!
Regarding Dr. Wille, he was my father’s GI doc and helped him live some 20 years after his colon cancer. As for me, I’m in my early 60’s and Dr. Wille is well aware of my family history, taking great care of me and has a great bedside manner.
I met Nicolette this week for the 1st time and she was easy to talk to (even if it is/was a difficult conversation).
But, what impressed me was the staff in the office. The TEAM (receptionist, the nurse who checked me and made me ready for the procedure, Anesthesiologist and nurse in the procedure room, the recovery room nurse, the PA who called me later in the day to check-up on me) showed me such care and compassion. It made me feel as if I was the most important patient that they would encounter.
It is obvious that these professionals love what they are doing. They love helping others. That made all the difference to me.
Thank you.
Outstanding professionalism with everyone I interacted with. Roger my RN was amazing. Got my IV started painlessly and was a pleasure to talk with.
Highly recommend
