I took my daughter (now 5 years old) three times to Dr. Han for routine checkups/cleaning between June 2007 and June 2008. There were no problems during the first two visits. However, on the third visit, my daughter--who has been going through a "nervous" stage--became fearful and upset. Dr. Han showed little patience or understanding and used strong-arm tactics to force my daughter to open her mouth. (He even ridiculed her for being fearful!) That made the situation much worse, prompting me to end the visit abruptly and take my child home.
