Erik S. Groothuis

Mr. Groothuis has spent over 20 years litigating complex commercial disputes. Although he focuses on the financial services and real estate industries, he has represented clients in accounting malpractice, business divorce, breach of contract, corporate governance, defamation, insurance, securities fraud, and torts litigation as well as related appeals.
