After many years of utilizing numerous attorneys on various legal matters, we were very fortunate to find Mahyar Ghassemian. We finally found an attorney who is not only extremely skilled and competent, but also goes far above what is required in representing us because she genuinely cares about her clients.
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.
I’d been searching for someone to handle the problem of collecting from the occasional client who refused to pay for my services—and to recommend to my own clients who encountered the same problem. Attorneys and collection agencies I’d spoken to weren’t interested in dealing with the small amounts my clients typically billed their customers. Then I met Mahyar Ghassemian, who has a passion for collections…and no minimum! Because of her efforts, the client agreed to settle for nearly the full amount! I’d encourage anyone who wants results to turn to Mahyar Ghassemian for their collection needs.
