Gary has more than 30 years of litigation experience in both the state and federal district courts throughout the State of California, handling cases from initial client consultation through trial and appeal.

His practice covers a wide range of business and business-related matters, such as shareholder disputes, corporation, partnership and joint venture disputes, intellectual property claims (including copyright infringement, trademark infringement, and misappropriation of trade secrets litigation), contract disputes, class actions, unfair competition and related claims under California Business and Professions Code sections 17200 and 17500, litigation under the Federal Debt Collection Practices Act and the California Rosenthal Debt Collection Practices Act, financial institution litigation, franchise disputes, and professional liability defense (attorneys, architects, insurance brokers, and agents).

He has extensive D&O experience and regularly defends both businesses and management in shareholder actions, and cases involving fraud, misappropriation, breach of contract, and breach of fiduciary duty.  He also has represented professionals, individual entrepreneurs, partnerships, and small and large companies in numerous industries, including accounting, banking, law, architecture, insurance, technology, manufacturing, printing, oil, gas and refining, alternate energy, debt collectors, and fashion.

In addition to his successful track record in litigation, Gary has achieved successful results on behalf of his clients outside of litigation through business counseling and skillful negotiation. His philosophy is to fully understand his client’s business, goals, and strategies, so that a result consistent with those goals and strategies can be achieved whenever possible. This philosophy results in a cost-effective and efficient approach to achieving the best possible results for his clients.
