"Dr Karen Steffer is a very good Doctor. She actually takes time to explain her examination to you and answers all your questions you have. The staff at Lone Star Endoscopy is great and makes you feel as comfortable as possible. They really care about your well-being and go out of their way to make you feel good that you on at their facility. This was my fourth Colonoscopy and endoscopy, but first one at Lone Star and rate it above the other 3 I have had."

"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!"

"First off Dr. Steffer is excellent at her job. She manages to be persistent without being annoying which is a great trait in general. The office is well run and you always get to see her which is nice as so many other doctors tend to do a "Lord Lucan" and just pass you off to a nurse. She also has a sense of humor and she's cute. What more could you ask for?"
