John Sullivan’s extensive experience in representing law firms of all sizes allows him to understand claims raised by aggrieved clients and work with firms to respond to and resolve those claims informally or, when necessary, through litigation.

Since joining Long & Levit in 2005, he has focused his practice almost exclusively on law firm defense. John has defended attorneys in state and federal courts, resolving claims at the pleading stage, summary judgment, mediation, trial and arbitration. During this time, he also has represented attorneys in State Bar matters, advised firms regarding partnership disputes, and prosecuted fee claims. John also counsels firms on liability and ethics issues.

John currently serves as the Chair of the San Francisco Bar Association Legal Malpractice Section. He frequently presents on professional liability topics and regularly contributes a risk management article to the San Francisco Bulletin, a monthly legal periodical. John also has been asked to comment for publications on California Court of Appeal decisions relevant to ethics and professional liability.

Aside from representing professionals, John has experience handling personal injury and product liability cases as well as commercial and corporate disputes. In defending claims against attorneys, John has gained in depth experience in numerous areas of law, including antitrust, class actions, water rights, federal tax, public finance, employment, and issues involving corporate governance.

John received his J.D. from the University of California, Hastings College of the Law in 2005. While at Hastings, he served as an extern for the Hon. Paul Alvarado (Ret.), San Francisco Superior Court.
