Tampa and St. Pete-based Trenam Law appointed Nelson Castellano as the firm's new managing shareholder.

Castellano succeeds Marie Tomassi after her more than 10 years in the role, the law firm says.

Castellano has practiced with Trenam for more than 30 years, becoming a shareholder in 1999 and previously serving on the firm's executive board, according to a statement. 

Castellano earned his law degree from the University of Florida Levin College of Law and earned his undergraduate degree from Florida State University. Since joining Trenam in 1992, Castellano held positions on the firm's executive board and as co-chair of the firm's Business Transactions Practice Group.

Castellano also serves on the board and executive committee for the Florida Venture Forum, the state's largest support and networking organization for entrepreneurs and venture capitalists. He was active for 15 years with Vistage Group 2095, and is currently a member of the Florida chapter of Young Presidents Organization. In the community, Castellano serves as a board member and on the executive committees of Junior Achievement of Tampa Bay and Zoo Tampa at Lowry Park.

As managing shareholder, Castellano will rejoin the firm's five-member executive board to lead alongside Michael Reeves, Trenam board chairman. The board also includes members Lara Roeske Fernandez, Robert G. Stern and Marie Tomassi.

"Trenam has remained on an excellent path with success in recruiting, associate development, diversity throughout our ranks, investment in innovative technology, and many other key elements for providing excellent counsel to our clients," says Castellano. " Together, we are well-positioned to continue as a leading firm in these areas and beyond."

Tomassi will continue to serve as the firm's president and executive board member, as well as appellate practice group leader, the firm says.

"We are extremely fortunate to have had Marie's longtime service in this role to lead our firm successfully, even through some historically challenging times, and we are grateful for her continued leadership as president serving on our executive board," says Reeves, chairman of the executive board at Trenam Law.

Trenam was founded in 1970 and has offices in Tampa and St. Petersburg. Its specialties include bankruptcy and creditors’ rights, business transactions, cybersecurity and data privacy, employment law, intellectual property, and more.

The firm is a member of MSI Global, a major international network of legal and accounting firms that allows the firm to source local expertise worldwide for its clients.
