This review is for the work that I receive from Dr. Yang's dental hygienist, Samira Snaif. The whole office is highly trained, professional and friendly. Dr. Yang does the big work that I sometimes require and he is tops. However, my most frequent contact is with my hygienist, Samira, Not only is she so nice to work with, but she explains what is happening and, after many years of ignoring the advise of the hygienist, has gently convinced me that good technique will pay off. I brush & floss as an old guy more than i have in years. The results prove that her gente urging works. BTW, she rocks.!
