What Our Patients Say

The best oral surgeon I’ve been to you and the last one I hope!!

I feel so fortunate to get referred to Dr. Saiz at Southwest Oral Surgery. I have had many surgeries but have never had a surgeon as kind and competent as Dr. Saiz. If you require facial or oral surgery you should contact Dr. Saiz. I promise you will not regret it. I also want to mention the outstanding staff at Southwest Oral Surgery. The day before I retired I fell at work and broke several bones on the right side of my face. It was very painful. Dr. Saiz took my workman's comp case and got me admitted to Banner Thunderbird for pain management. My surgery was on June 1 a Saturday. Considering the level of repair my face required, everything went fairly well. Dr. Saiz called me in the hospital to check on me. I am so glad I was referred to Dr. Saiz.
Dr. Saiz is absolutely the most amazing oral surgeon! He was thorough, made sure it was done correctly. And most important, he truly hears and cares about his patients. 24 hrs later, I'm doing great!!!Office staff in front and back are exceptional!I can't say enough about this experience. Kudooos all the way around!!❤
