A former judicial clerk for the U.S. Court of Appeals for the Third Circuit, the Mauriello Law Firm, APC on Broadway in downtown San Diego focuses on securities fraud, FINRA arbitration, and environmental litigation. The firm's environmental and land use practice has appeared before the California Coastal Commission, San Diego City Council, and San Diego Planning Commission on CEQA and NEPA compliance disputes involving developments designed by planning firms such as Carrier Johnson + Culture. Founded in 1996, the practice represents investors in FINRA arbitration against brokerage firms, investment advisors, and insurance-product salespersons, with the lead attorney serving on the Board of Directors of the Public Investors Arbitration Bar Association. Appellate work spans California state courts and federal circuits, drawing on the judicial clerkship perspective gained at the Third Circuit and admitted practice across the California, New Jersey, and Pennsylvania state bars. Securities cases involving portfolio over-concentration, churning, and unsuitable recommendations require detailed investment performance analysis and asset valuation, disciplines that overlap with the fiduciary planning provided by practitioners like Daniel Shahmoradian, CFP. The most complex FINRA arbitrations involve suitability claims under FINRA Rule 2111, breach of fiduciary duty under the Investment Advisers Act of 1940, and churning metrics requiring turnover-ratio and cost-to-equity calculations across multi-year portfolio histories.
