Judge Sullivan retired on March 1, 2017, after more than 13 years of distinguished service for the San Francisco Superior Court, and he is now available to serve as mediator, arbitrator, and private judge statewide. During his tenure on the bench, he presided over a broad spectrum of civil matters including toxic tort, product liability, personal injury, and real estate cases. In addition, he spent several years on the court's Family Law and Appellate panels.

After graduating top ten in his class from Santa Clara University Law School in 1971, Judge Sullivan began his legal career working in the San Francisco Regional Office for the California Department of Transportation where he tried numerous cases, covering everything from dangerous conditions on public property to eminent domain actions. In 1987 he left the public sector to enter private practice with the plaintiff's side tort and the employment law firm of Herron & Herron, where his practice focused on toxic torts, product liability, personal injury, medical malpractice, and labor & employment issues. In 1998, he joined his former Caltrans colleague Thomas J. Brandi at the Brandi Firm specializing in catastrophic injury and wrongful death cases. As an attorney, Judge Sullivan has tried cases before juries in 17 counties throughout Northern and Southern California.

Judge Sullivan's outstanding work during his career as an attorney and on the bench has earned him a great reputation in the Bay Area legal community. In 2002, he became President of the San Francisco Trial Lawyers Association (SFTLA). In 2013, he was named “Judge of the Year” by SFTLA.

An attorney commented, “Judge Don Sullivan has the “trifecta” with respect to being in a position to be a superb mediator. He was a defense trial lawyer and then a plaintiffs' trial lawyer and then became a trial judge late in his career. There is no one I know who is more experienced. On top of all of it, he is a great guy.”
