5.0 Review from K.M. Source: Google Feb 06 2020

"DR. Marek is one of the finest clinicians in his field. As a retired Army clinician, I find that DR. Marek operates at the highest level of professionalism, state of the art practices and holds his staff to the same standards. Truly a rare find from the apathetic and disengaged doctors that predominantly advertise big and deliver small. DR. Marek is an outstanding individual, his skill set and clinical knowledge are second to none, maybe I need to swear him in and get him an Army uniform. I’ve always felt that delivering anything less than world class health care is failure, you will be treated with respect, your condition explained in detail and your questions answered. His staff is a reflection of his personal desire to deliver the finest care possible. There is no one better. CPT Ken McKenzie, RN APN, CEN, CFN US Army (ret)"

"Dr Marek is great. He had an aggressive approach - not just 'try these antibiotics' and now my chronic problem has been solved in weeks!"

"In spite of a significant wait I would absolutely recommend seeing Dr Merick in the New Braunfels location at 2028 Sundance Parkway. Although we were not told a reason, Dr Merick himself apologized on 3 occasions for the wait. The Medical Assistant and front office followed with their own apologies. Dr. Merick is totally engaged while in the exam room. All of my questions were answered and I left feeling confident in the upcoming procedures."

"I have been seeing Dr. Marek for several years and can't say enough about him. He has truly saved my life. He talked me into finally having the procedure that I was so scared to have by outlining exactly what he would do and what the experience would be like in an understandable and caring manner. I am SO GLAD that he did. As much as it hurts me to say, HE WAS RIGHT! I had a large mass and he was able to remove the entire mass during my scope and I didn't need any surgery! I went to see an oncologist who couldn't believe that Dr. Marek was able to remove the mass and she told me that most other gastroenterologists wouldn't even have attempted removal. I needed no further treatment and am cancer free because of this man and his personable bedside manner! I am so thankful to have found him and refer him to as many people as I can."
