  • Patrick Baghdaserians

    Marshall is a pillar of the family law community. I had the privilege of litigating a highly contested custody matter against him. Notwithstanding the type of case, Marshall was professional and straightforward throughout the matter. We ended up resolving the matter on the courthouse steps so to speak. This was truly the best option for both parties. I highly endorse this lawyer.
