Thomas (T.J.) Mitchell is an associate in the Commercial Litigation practice group. T.J. partners with Polsinelli’s seasoned attorneys to provide litigation solutions in complex financial and business disputes, manage clients’ risk, and allow 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
  • Mergers and Acquisitions litigation
  • Diverse business contract and tort actions
  • As part of the team of Polsinelli lawyers who have a FinTech practice, represent companies, their principals, and employees in the crypto currency industry during investigations by the SEC and the CFTC. 
  • Represented a registered representative in a FINRA arbitration against allegations of fraud, misrepresentations and non-disclosures, elder abuse, breach of fiduciary duty, and suitability. The claims were denied in their entirety. After the hearing regarding expungement of the claims from the representative’s BrokerCheck and CRD, the arbitrator found the allegations were false and granted the request for their expungement.
  • Participated with other Polsinelli lawyers in the representation of an insurance agency and five of its agents during investigations conducted by the SEC and the Arizona Securities Division, and the proceedings these agencies filed against our clients for their alleged role in placing $17 million of notes issued by a $1.2 billion Ponzi scheme. 
  • Participated with other Polsinelli lawyers in the representation of an investment adviser who was forced to leave his firm by his partner. The AAA arbitration resulted in an award in favor of our client in excess of the $1 million sought for the buyout of his partnership interest, pre-judgment interest, post-judgment interest, and attorney’s fees and costs.
