About Patrick J.
Patrick J. McMahon earned his Juris Doctor from the Elisabeth Haub School of Law at Pace University in 2000. He completed his legal education at a time when New York’s courts and regulatory landscape were evolving rapidly. The degree provided a foundation in core subjects and practical skills that would shape his later work.
After law school McMahon began practicing law in New York. He is admitted to practice in the state and has built a career tied to its courts and administrative forums. Over the years he developed a steady practice and became associated with Osorio Cachaya Law Offices, PLLC, where he continues to work.
At Osorio Cachaya Law Offices, PLLC McMahon handles a range of client matters. His responsibilities include advising clients, preparing filings, and representing clients before tribunals and agencies when necessary. He works alongside colleagues at the firm and contributes to case planning and legal research.
His professional life includes active involvement in the New York Bar Association. That membership keeps him connected to peers and to continuing legal education opportunities in the state. Participation in the association provides access to resources and discussion on developments in New York law.
Colleagues describe McMahon’s approach as practical and attentive. He focuses on the procedural and substantive elements that matter most to clients. He pays attention to deadlines and to the preparation that underpins filings and hearings. Those habits aim to reduce surprises and to present matters clearly in writing and oral argument.
Outside of firm work, McMahon has maintained ties to the larger legal community in New York. He stays current through legal publications, seminars, and the professional networks available through the bar association. That ongoing engagement informs how he manages cases and advises clients.
As of 2026 McMahon is practicing at Osorio Cachaya Law Offices, PLLC, where he handles legal matters arising under New York law.
