Co-founders and Managing Partners of Griffin & Prescott. Each remains personally engaged on the firm's most significant client matters.
Jason Marcus and Phillip Osei founded the firm together on a shared conviction: that institutional and individual clients deserve senior, sustained partner attention from first conversation to final resolution.
The two Managing Partners maintain distinct but complementary practices. Jason concentrates on regulatory enforcement defense, financial-crimes compliance, and the cross-border investigations that increasingly define how multinational institutions operate. Phillip leads the firm's litigation practice and personally tries the matters that cannot be resolved on the file.
Together they set the firm's cultural standard: candid client counsel, partner-led teams, integration across practice areas where matters require it, and the willingness to engage where the questions are hardest.
Co-founder of the firm and architect of the multidisciplinary practice that anchors our work in regulated industries.
