With over 30 years of experience, Michael McMahon focuses his practice at Carmel & Naccasha LLP primarily on civil litigation in the areas of employment, business, public agency, and real estate law.


Mike has substantial background representing both private businesses and public agencies. Practicing law since 1992, he has tried cases on behalf of one of the country’s largest telecommunications companies. He routinely provides extensive advice and counsel to clients on employment-related matters and has grown his practice to also include land use matters.

Mike has handled cases on behalf of numerous cities and special districts in southern California and on the Central Coast. He is familiar with the Tort Claims Act, public entity defenses and immunities and writ proceedings. He has represented public agencies including the City of Arroyo Grande, Cambria Community Services District, San Miguel Community Services District and Templeton Community Services District. Mike regularly represents public agencies on employment related matters from initial discipline to trial. He also has experience conducting personnel investigations and provides advice and counsel on labor and employment issues to local businesses.

Mike moved to San Luis Obispo County in 2005, taking a position as a Court Attorney with the San Luis Obispo County Superior Court. At the Court, Mike dealt with a wide range of civil matters, researching and drafting memoranda to SLO County Superior Court judges with recommended rulings on contested matters. These cases involved real estate transactions, boundary disputes, insurance matters, class actions, actions by and against public agencies and petitions for writs of administrative mandate. Mike also regularly served as a judge pro tem during his tenure as a Court Attorney.

Mike joined Carmel & Naccasha LLP in 2007. In 2009, Mike opened the firm’s Paso Robles office, where he continues to practice. Since then, the Paso Robles office has grown to include four attorneys, a paralegal and legal assistant.

Great advisor
Mike was awesome in communicating different information to me in plain language, not the typical "lawyer speak". More than anything I appreciated how quickly he handled everything and how at ease he always made us feel. He will continue to be our legal advisor for any issues we may have.
