Mahyar was a big part in helping start our company and setting up our corporation. She also went to battle with a Billion dollar Corporation to keep our doors open when they tried everything to shut us down.

In 2008 -2009, our company was involved in a lawsuit with over 1 million dollars claimed against us. Mahyar Ghassemian handled our case expertly and conscientiously. She explained on a regular basis the progress of our case and how each of the actions of our opponent would ultimately affect our case. At no time did we feel alone or compromised as Mahyar boldly stayed her course which eventually provided us with the satisfactory outcome we had hoped to achieve. She will be our first call should the need arise in the future.

Many years ago an insurance carrier hired Mahyar Ghassemian to defend my construction firm in civil litigation. Not only was Ms. Ghassemian very knowledgeable and competent regarding the legal proceedings, but she was also personally vested in our well-being; she cared what happened. She counseled us regarding the various options, listened to our input and proceeded accordingly. In multiple cases with Ms. Ghassemian, we have never experienced a negative outcome. Today my first call when a potential legal issue is on the horizon is to Ms. Ghassemian. She is both extremely effective and cost conscious.
