He also advises on insurance policy placement and review; risk avoidance, transfer and management; and alternative dispute resolution methods, techniques and enforceability.  Greg has had an active trial and appellate practice. He has helped defeat and defense multi-million dollar claims and suits and obtained eight-figure verdicts and judgments and hundreds of millions of dollars in settlements. He also has argued and helped obtain published decisions at the California Supreme Court and state and federal appellate levels that have changed the course of California law and practice.
