Ochsner Patient Verified Reviews
To obtain patient ratings and comments, we partner with Press Ganey, an independent patient satisfaction company that works with more than 26,000 healthcare organizations to improve the patient experience. These patient verified ratings are based on the “likelihood to recommend” physician scores on the nationally developed Medical Practice Survey. Actual top box results for this question are translated to a 1-5 scale, and the star scores are measured on that scale, with 5 being the best score.
I was in for 16 yr. cancer check up. Doctor is very thorough and listens/answers all questions.
Dr. Theo is ALWAYS on time! He always explains how I'm progressing and any next steps. I have literally trusted him with my life and feel safe & secure in his care for me.
Dr. Theo is extremely compassionate and understanding. He exhibits professionalism with the ability to listen to his patients. He has been my source of strength and positivity throughout my cancer journey. I appreciate that Dr. Theo is my oncologist and that he has not been replaced with a nurse practitioner or physician assistant.

Dr. Theo has been my doctor for almost twenty years. I have no complaints at all.
I wish there was an "excellent " or "outstanding" option. Dr. Theo's care was far beyond "very good"-- He clearly explained the results of my mammogram and prognosis. He clearly outlined my options for annual follow-ups and gave me full information so I could make a reasoned decision. He was respectful, knowledgeable, kind, and caring throughout the appointment. I am truly blessed to be his patient.
Dr Theo takes his time in explaining things and answers any concerns I may have
