Dionna came to Tully Rinckey PLLC with an extensive amount of experience practicing labor and employment law.

Dionna also counseled clients on a wide variety of employment, civil rights, contract and business litigation matters, including terminations, severance packages, breach of contract and employment agreements. Previously, Dionna completed a judicial clerkship at the D.C. Superior Court and gained experience drafting judicial orders and opinions. While in this position, Dionna reviewed incoming motions, made recommendations on pleadings filed with the court and advised the judge on case matters and upcoming hearings. Prior to joining the team, Dionna served as fair lending counsel at the Consumer Financial Protection Bureau (CFPB) in the Office of Fair Lending and Equal Opportunity, where she investigated fair lending risks and civil rights violations at some of the nation’s largest financial institutions.
