He is like having a Dad who's your dentist. I grew up going to his office, and when I had to get a filling done in Los Angeles, it was so expensive and the offices I called were very rude. So I called Dr. Robertson's office, and I am going to wait with this temporary filling until I can go back to him and have my tooth done right.
Pros: Very smart and experienced and reassuring
Cons: Airfare (haha!)
