Isaac Colunga is a partner in the firm’s Business Litigation Group and works in the Chicago office. Isaac represents clients in consumer class actions, contract and commercial disputes and employment cases.

The TCPA, FCRA and Other Consumer Class Actions
For years Isaac has defended clients in Telephone Consumer Protection Act (TCPA) and Fair Credit Reporting Act (FCRA) cases filed in federal courts around the country. He has served as lead or co-counsel in well over 100 TCPA and FCRA class actions nationwide. He’s obtained favorable class and individual settlements; he’s had cases dismissed; he’s won on summary judgment; and he’s defeated class certification. Because of his experience, Isaac has developed relationships with members of the plaintiff’s bar that routinely file these suits, and many clients rely on Isaac to provide compliance counseling before starting fax, phone call and text messaging campaigns. Isaac’s clients range from middle market companies to multi-national corporations that hail from a variety of industries, such as pharmaceutical, retail, communications, supermarket chains, software and technology, healthcare, information and delivery, cosmetics, consumer goods and staffing. 

Contract Litigation and Unfair Competition 
Isaac also prosecutes and defends clients in cases involving oral and written contracts, including foreclosure actions, breach of contract suits, breach of fiduciary duty claims, fraud, accounting and other claims arising out of the following:
  • Data Use and License Agreements;
  • Software Licensing Agreements;

  • Lease Agreements;
  • Equipment Lease Agreements;
  • Executive Employment Agreements;
  • Asset Purchase Agreements;

As part of this work, Isaac also files and prosecutes claims for violations of non-compete agreements and misappropriation of trade secrets. He has successfully obtained injunctive relief on behalf of his clients to enforce their restrictive covenants, to maintain customer relationships and to prevent the loss of intellectual property. 

Employment Litigation
Isaac also assists employers with investigating and litigating claims for employment discrimination, wage and hour violations, human rights claims and harassment. He has represented clients before the Illinois Department of Employment Security, the Illinois Department of Labor, the Illinois Department of Human Rights and in state and federal courts throughout Illinois in such cases.
