About Campbell Walter
Campbell Walter Filmer studied law in New York, earning his degree from New York Law School. He moved into practice in a period when cross-jurisdictional work was becoming more common, and he now holds licensure in both New York and California. Those admissions have shaped a practice that spans two major state systems.
Filmer's career includes a long association with The Law Offices of Anthony E. Vieira. That firm appears throughout his professional record. Over time he has worked on matters that required understanding the procedural differences between New York and California courts, and he has navigated the administrative and practical demands of practicing in two states.
Beyond day-to-day casework, Filmer has remained engaged with professional circles. He has maintained memberships in organized legal groups since the mid-2000s, a period that coincides with his growing responsibilities at the firm. Those memberships have kept him connected to developments in both states and provided forums for continuing legal education and peer exchange.
Colleagues describe him as steady in the office and methodical in legal preparation. He approaches client matters by assembling factual records and then applying the relevant statutory and case law. That methodical approach is suited to the often procedural differences encountered when cases cross state lines or when filings must satisfy multiple local requirements.
Filmer also handles the practical side of running matters through the court system. He is familiar with filing protocols, calendaring, and the logistics that keep a case moving. Those tasks are less visible than courtroom appearances, but they are essential to resolving disputes and advancing client interests.
He remains based at The Law Offices of Anthony E. Vieira, where he conducts his practice and serves clients in both New York and California. He currently practices at The Law Offices of Anthony E. Vieira, representing clients in matters that arise under New York and California law.
