Mr. Koss represents professionals and their businesses, particularly in real estate litigation and lawyer malpractice, and serves as appellate counsel on a wide range of subject matters. His representation of each client is focused solely on achieving the best outcome for that particular client. After formulating an appropriate litigation plan in conjunction with his clients, Mr. Koss works forcefully towards those unique and tailored goals. Based upon his clients' litigation needs, Mr. Koss has negotiated numerous pre-litigation confidential resolutions which keep those matters out of the public record, has represented clients in early and cost effective arbitrations, and has had particular success using pre-trial filings such as anti-SLAPP motions and motions for summary judgment. Throughout litigation, Mr. Koss keeps an eye on his clients' best interests and is always willing to explore resolution on favorable terms. He does, however, recognize that some cases must be decided by a jury, and has served as trial counsel on numerous occasions.
In many cases even a successful dispositive motion or trial is not the end of the matter. There are also times the trial court just got it wrong. When those needs arise, Mr. Koss is experienced in handling matters at the appellate level in both State and Federal Court. His time spent as a law clerk with Justice George W. Nicholson at the California Court of Appeal, Third Appellate District provides insight and a unique perspective on handling appellate matters.
Although he focuses predominantly on professional defense and appellate work, Mr. Koss also represents clients in a variety of other fields, including commercial real estate, business formation, governance and dissolution, administrative proceedings, and in products liability, employment law, contract, and general negligence litigation.
Mr. Koss is a member of the American Bar Association, Bar Association of San Francisco, San Mateo County Bar Association, and the Defense Research Institute. He volunteers on the Ninth Circuit Court of Appeal Pro Bono Project. Mr. Koss spends his free time running after his young daughters, and tries to catch a ball game whenever possible.
