Ruptured Intestine - CHI St. Lukes at Woodlands I had have never met a doctor as amazing as Dr. Johnson. He is not only great as a surgeon, he actually cares for each one of his patients. After i was released from the hospital i called his office to inquiry about a pain i was having, he actually personally returned my call!! I am so thankful to God and him for saving my life!

I have seen any number of physicians/surgeons over the years and consider Dr. Mark Johnson one of the most thorough and approachable ever. We learned of him through an article in the newspaper that described a new procedure he was doing, which was exactly what I needed, having had it fail twice previously. He explained all details, did an excellent job on the surgery, and was extremely informative and understanding. He has a pleasant demeanor and shows concern for his patients.

I had a very complex hernia from prior intestines surgery. He was able to fix it using the robot. I am so thankful to him. He helped me start living again !!!!

Dr. Johnson fixed my hernia with the robot after a failure by Tomball surgeon. He did an excellent job. I would have it done again 1000 times by him.

Excellent results

He told me it's "not his responsibility" to look at medication charts nor did he know my age. All he cared about was surgery,although he tries to make you think he doesnt. He left me in a lot of pain due to his ignorance of not looking at my chart. I was released after surgery left to deal with my pain and never checked on me. Stay away from this surgeon!

He is very thorough and has kind staff.
in The Woodlands, TX |
Efficient but extremely communicative, patient, informative. Amazing bedside manner for a surgeon who quite clearly has a full plate. Wonderful with my daughter and made the process less anxious for us. Checked on her after hours, both before and after surgery. Highly recommend he and his staff, and the Conroe Surgical Center!
in Huntsville, TX |
My initial appointment with Dr Johnson went well. I found him personable and pleasant. He treated me like an intelligent adult and answered all my questions. The time with him was not rushed. Surgery was scheduled in a very reasonable time frame. The surgery went very well and was just as he said it would be. I felt confident with him as my surgeon. Recovery has been excellent. My follow up appointment is in a few days.
in Livingston, TX |
