Mahyar Ghassemian

Mahyar Ghassemian, Esq., is a California attorney and managing attorney at  Ghassemian Law Group, APC, who focuses on construction litigation, business law, real estate matters, and preventive legal planning. She represents contractors, developers, architects, engineers, business owners, shareholders, and other clients facing serious legal problems. Her work includes complex construction defect claims, public works disputes, partnership issues, contract problems, collections, mechanics liens, and commercial litigation. Mahyar uses practical strategy and careful case preparation to protect client interests and reduce legal risk.

Mahyar earned a Master’s Degree in Physics from California State University, Long Beach. She also earned a J.D. from Western State University College of Law, graduating cum laude. Her science background helps her understand technical facts in construction cases, especially when expert reports, building defects, engineering issues, or detailed evidence must be explained clearly. Her legal education and early court experience helped build the litigation skills she uses in negotiation, mediation, arbitration, and trial-related work.

Mahyar has more than 25 years of litigation experience across construction and business law. She clerked for the Presiding Justice of the California Court of Appeals while in law school and was sworn in after completing that early legal work. She later handled business and construction litigation with Southern California civil litigation firms before building her own practice. Her career includes high-value disputes involving public works, corporate governance, shareholder conflicts, construction defects, and claims against large companies. These matters required careful evidence review, direct client guidance, and a strong command of both legal and technical issues statewide and efficiently.

Mahyar Ghassemian helps clients by giving clear advice before problems grow and strong representation after disputes begin. She drafts and reviews contracts, advises during construction projects, and helps businesses plan better structures to avoid conflict. When litigation is needed, she works to limit exposure, shift liability where supported, and pursue practical results. Her clients benefit from her technical training, courtroom experience, and focus on solving difficult disputes with steady legal judgment.
