Gabrielle Jackson's practice has focused on the representation of attorneys and accountants in malpractice actions, the defense of Director and Officer liability claims, and the defense of judges and commissioners in disciplinary matters pending before the California Commission on Judicial Performance. Her work has repeatedly demonstrated to the Commission that either no discipline should be imposed, or that discipline should be private.

Before deciding to become a lawyer, Gabrielle was a senior accountant at a life insurance company, completing the written requirements to be a CPA, before changing career paths. Because of her background in accounting, family law and employment law, she regularly works on malpractice actions which arise from underlying cases in those fields. She often handles cases in which a series of malpractice actions are generated from a unique practice area, including the successful representation of law firms in several cases arising from disallowed tax structures. She regularly defends matters brought by bankruptcy trustees and receivers. She is the firm expert on jurisdiction and venue and on the right to and procedures applicable in arbitration.
