Dr. Sonabend is THE BEST Dermatologist in Houston area. I had severe acne on my face for 18 years. I saw a number of specialists in Houston (Beechnut Professional Building and near HCA Houston Healthcare West) during this time. I was treated with all sorts of medicines, lotions, creams but could not get rid off the acne. I got to a point where I had lost all the faith in the dermatologists and didn't do anything for several years until my family physician referred to Dr. Sonabend. During my first visit with him, I provided him with a list of all the medicines, lotions, etc. that I had taken during the last 18 years. He went through the list and said that this is no way to treat acne of this severity. He performed tests on me and pinpointed the root cause. I started using the items that contained these chemicals. That was 7 years ago. Since then I have not experienced any severe cases of acne.
