excellent experience!

I repeatedly must ask Dr. Han to explain what he is saying due to dialectical barriers, He appears somewhat annoyed when I am trying to inquire on my daughters behalf and cannot understand him.

My 9-year-old daughter commented how much she liked Dr. Han. She said, Hes the only doctor or dentist that has talked directly to me instead of talking to you about me. Its true! He explained to her all of the things he was suggesting and my daughter felt very respected.

I really appreciate that Dr. Han isnt trying to force us into braces. He gave us an honest assessment and suggested we wait for a year or so, saving us money and saving Gus from needing 2 rounds of braces. I really like Dr. Han.

I was kind of scared when they said they were going to take my heyrex out! and they kind of made me less scared.
