Dr. Jan Adams, who performed surgery on Kanye West's mother a day before her November 2007 death, has given up his medical license, according to the Medical Board of California.
"A series of complaints were filed against Mr. Adams, but he chose to surrender his license instead of contest them," Medical Board spokeswoman Candis Cohen said in a statement. Among the complaints: Two DUI convictions and failure to pay child support. His record also shows at least four malpractice judgments against him between 2001 and 2007.
