About Me

My legal practice is focused exclusively in litigation, with a primary area of emphasis in corporate ownership disputes and business dissolutions ("business divorce.") My clients are the owners, officers, and/or directors of privately held companies who need creative and aggressive representation for disputes arising out of breach of fiduciary duty, breach of loyalty, minority oppression, conversion, accounting, wage claims, unjust enrichment, and the business "divorce" often attendant thereto.

  • Brent William Beecher

    If I were going to hire an attorney to represent me personally in litigation, it would be Mario. Mario has an excellent ability to cut through the extraneous issues, get to what is important, and give informed, reasonable advice about the practical implications of getting particular results. I have worked with him and against him, and have found him to be courteous, professional, and effective. I recommend him highly.
