Dr. Garza and his staff were very professional and attentive. Prior to the procedure they were thorough in attaining my medical history to ensure no obstacles were present. I tip my hat to Dr. Garza and staff for their pre- and post- procedure caring attitude. Job well done.

Dr Garza was my husband's doctor for his colonoscopy. Dr. Garza was very thorough, easily understood and went over the scan procedure in detail. We felt he was very capable, informative and caring.
