Hear What Our Patients Are Saying
I’m completely satisfied with the work Dr Tamez has done in my surgery and post-op care. He is very thorough and thoughtful, and advocates a holistic approach, working with my dentist and my sleep doctor, to help me improve and maintain my health in all these areas. I recommend him highly!
David Orr
Jennifer, the NP here, was amazing. Spoke to me clearly about what she was going to do in terms of process, allowed me to describe everything I was feeling, and advised me on what the next steps are for me clearly. She did not rush through it and was a true professional. Outstanding experience, including a friendly staff to greet you as soon as you walk through the door.
Victor Garcia
Dr. Tamez and his staff are superior to the rest! I always felt welcome and well informed with my consultations and especially well taken care of during my septoplasty surgery. Thank you!
Tina Signorello
Dr. Tamez spends a lot of time with me going over my treatment for sleep and breathing issues. He was very patient in explaining the reasons for my symptoms and answered any and all questions I had to my satisfaction. The staff that welcomed and prepared me were very courteous and professional. A very good experience. Highly recommend Dr. Tamez.
John Hernandez
Dr. Tamez is great at what he does! We have had a wonderful experience. Our son’s breathing has improved greatly and we are thankful for it!
Jocelyn Coughlin
Tejas Ear Nose and Throat was wonderful. My daughter Ava had her tonsils and adenoids taken out a month ago and everything went great. Dr Tamez was so personable and informative. She had no issues with recovery and is doing great.
