I went to this guy because I live in North Beach and he's local...I'd seen his sign on Columbus. I had an abcess and was new to the area and needed a dentist's care right away. He wouldn't take any form of payment but cash! I have all the usual types of credit cards and when I asked if he'd take them he said, if you have a credit card go downstairs to the ATM and get cash using it! The whole thing was bizarre and the office creepy and old. Because he seemed so angry and unprofessional I sought treatment elsewhere (from Dr. Wallace Woo, down the street on Colombus, who I've gone to ever since).
