  • Paulette Gharibian

    I was referred to David by a colleague when I needed a criminal defense attorney to weigh in on an overlapping criminal/family law matter. He quickly returned my call, offered excellent advice, and followed through to ensure the issue resolved to my client's satisfaction. I find David to be an expert in his field and look forward to continuing to refer all criminal law matters to him.
