Marissa’s practice focuses on corporate litigation, class action defense and both internal and external investigations. Her substantial experience includes securities and finance-related cases, matters governed by the Uniform Commercial Code (UCC)&nbsp;and complex contract and insurance-related disputes. She has played a critical role in managing large-scale discovery and developing and implementing strategy for cases in which the liability threatens a company’s ability to do business.

Marissa’s background contributed to her versatility. After graduating from Northwestern University, she worked as a television morning news anchor for a handful of years. “Good Morning Central Texas” led Marissa to Dallas, Texas, where she started and managed a real estate company. She also served as judicial clerk for two federal district courts. The combination of these experiences culminated in Marissa's skill and understanding as a lawyer.

Marissa serves on the firmwide Women’s Committee, as well as on the Columbus office's Business Development and Recruiting Committees. She also holds a board seat on the Ohio Women’s Board Association and the Ronald McDonald House Charities of Central Ohio.
