T.J. Mitchell

T.J. Mitchell provides litigation solutions in complex financial and business disputes, manages clients’ risk, and allows clients to focus on driving their business or personal objectives. Drawing from his experience working in the legal department of a large technology company, T.J. understands what clients expect from their outside counsel or personal attorney and takes the time to understand their unique challenges, goals, and values. These priorities shape his work from the first client meeting through pre-litigation negotiations, preparing lawsuit or arbitration pleadings and briefs, conducting discovery, and resolving disputes either through settlement or trial.

T.J.’s practice focuses on representing parties in:

  • SEC, FINRA, and state-level regulatory investigations and proceedings in the securities brokerage and investment advisory industries
  • Civil litigation in federal courts, state courts, and arbitrations involving complex financial products and transactions
  • Director & officer liability litigation
  • Mergers and Acquisitions litigation
  • Diverse business contract and tort actions

Outside of his law practice, T.J. is honored to serve as a “Big” through Big Brothers Big Sisters of Central Arizona. He also serves on the board of directors for the Greater Phoenix Chamber of Commerce’s Valley Young Professionals.
