About Us

Experience matters. We are a team of fierce litigators who fight for you and do not give up until your company is safe from threats. Having a law firm on your side that has previously been involved in very complex and challenging business and construction legal fights gives your company an edge.

Our Managing Attorney, Mahyar Ghassemian, besides her law degree, has Bachelor’s and Master’s degrees in Physics and a technical background instructing engineering scientific classes. Construction cases are reliant upon experts, and analysis of numbers and plans. The ability to communicate with experts as a fellow scientist, and to translate complex scientific and engineering concepts and terminology into easily understood language is valuable for our clients as well as the Court and jury.

Our business clients rely on our experience in the real world. From corporate boardroom to the intricacies of business claims in the court room, our team has the business experience that gives us the in depth understanding that we then meld with legal expertise to manage complex legal issues for your business. We have served on the boards of various corporations, as well as successfully ran our own small businesses. We know what it takes to be in business and consistently put that experience and knowledge to use in our cases.


A rarity of its kind, Ghassemian Law Group is a small firm with big-firm experience. With over 20 years of experience, Mahyar Ghassemian has represented some of the nation’s largest businesses, builders and contractors in litigation as well as transactional matters, and now brings that expertise to a small firm environment to provide clients with the best of both worlds. The unique blend of our small operation with our vast legal expertise in complex, multi-million dollar cases means that we are ideally equipped to solve your legal matters regardless of the size or complexity.

I can’t say enough positive things about the incredible team at this attorney’s office. From the moment I spoke with them on the phone, I knew I was in capable hands. Even though I am a North Carolina business I had a very complex case in California. The law firm and attorneys were the best of the many, many law firms I interviewed. I can not say enough how easy they are to work with from start to finish.
Their expertise is unmatched. They navigated the complexities of my case with professionalism and confidence, leaving no stone unturned. Their depth of knowledge and strategic thinking were evident every step of the way.
What truly sets them apart is their genuine care for their clients. They listened to my concerns, answered my questions promptly, and ensured I felt supported throughout the entire process. It’s clear they care about their clients and they’re in it to make a real difference in people’s lives.
The professionalism and attention to detail displayed by this office are outstanding. They kept me informed, were always on time, and made sure I understood every aspect of my case. They turned a potentially stressful situation into a manageable one.
I’m incredibly grateful for the exceptional service and favorable outcome they delivered. If you’re seeking legal representation that combines expertise, compassion, and dedication, look no further. This attorney’s office is a true gem and worthy of every one of these five stars!

Mahyar Ghassemian and her firm are the best construction dispute litigators and negotiators in the industry. Mahyar is an expert in this area. Her firms knows the law and are very tenacious in obtaining the best results for their clients. I have been involved in very lengthy litigation as co-counsel in a very big case and jury trial. Mahyar is one of the hardest working and most effective advocates I have ever had the privilege of working with.
