Dr. Chang is amazing! His consultations are very thorough and he is certain to go over every care and concern. When it comes to treament planning, he is the best. I was able to have every procedure done in one office without the worry of going to a handfull of other specialist. He does EVERYTHING. The extractions and dental implants were completely painless and I've not had one problem so far. I will continue to see Dr. Chang for my cleanings and exams and would respectfully recommend him to anyone who has had long-term dental problems.
