"The toughest part about getting a colonoscopy is the week leading up to the procedure. What to drink, what to eat, and then the flushing of the colon. Dr. Steffer is kind, professional, and a real pleasure to have her as my doctor. She has performed three procedures for me and she and her staff make an embarrassing procedure for me a very nice experience. I am a bit OCD trying to memorize the names of every professional whom I enteract with while I am being prepped to go under for the procedure. I remember Chris, Greta, Leslie, Ann, and Showanda, who all had a hand helping Dr. Steffer help make my stay pleasant. In fact instead of counting backwards to go under anesthesia, I remember saying each person's name. Next thing I knew, I dreamt one of my dogs was trying to get my attention, but it was Ann waking me up."

"Dr. Karen Steffer was amazing! I have had an endoscopy many times and by many different doctors, but Dr Steffer was BY FAR the best. I needed to be seen right away, but I was a new patient of hers because my previous doctor stopped seeing patients. She scheduled my endoscopy for the day after my initial appointment and during her lunch break. I felt like she saved me. I was really struggling and she was compassionate and caring. Not only that, but she was excellent at her craft. I always wake up in pain after the procedures and it often times takes me a week to eat after them...but after my procedure with her, I had very little discomfort and was able to eat that day. I feel like I really lucked out when I found Dr. Steffer and I will gladly trust her as my doctor going forward. She was incredible!"
