Great doctor and staff!
the day I made my appointment through my procedure everyone was professional and made me feel comfortable
Highly recommend this office .
Thank you to everyone!
I again highly recommend Dr Wille. He cares, he's patient & thorough. I cannot express enough how wonderful Reneshia (nurse in scheduling) was. This event was extremely difficult for me & she calmed & reassured me all would be well. Thank you for having her in your practice!
My husband and I are both patients. We highly recommend Center for Digestive Health
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.
I can imagine that the medical profession is very demanding and I've been in offices where the Dr's have been short and barely stay in the room 2 minutes and I'm left with more questions than I walked in with but not with Dr Webber, I was the last appointment of the day and I'm sure he was ready for his day to be over but he stayed in there and answered every question that I had and was so kind and caring.
I highly recommend Dr Weber and his staff which were also completely amazing.
Thank you for showing that you actually care about your patients.
She’s got me. Alyssa told me she was using a 22 gauge which USA very small needle and she was able to get it in the side of my hand without me feeling a thing. OMG I cannot thank her enough.
I love Dr. Willie, who is definitely one of my favorite and best docs. So kind, understanding, thorough, easy to speak with, and I never feel rushed.
Thank you again for my wonderful care.
Excellent aftercare as well, called to make sure I’m doing ok later in the afternoon.
Jessica listened to my concerns and was very helpful . She explained things to me that I could understand .
Each staff member were very professional in their duties.
