Angela Hill of the Oakland Tribune reports: Dr. Derric DesMarteau, longtime team dentist for the Golden State Warriors, the Oakland Raiders and other sports organizations as well as a highly regarded private dentist with a thriving practice in Piedmont, died Aug. 20 from complications from cancer. He was 58. “He had such a love of dentistry, such an unbelievable passion for it,” said Rhonda Nelson, who worked with DesMarteau for 17 years as his office manager. “He could work magic with people. Patients came to him when other dentists said they’d given up on them, so he would often get unusual cases and restore their whole mouths.”
