Nelson Castellano did not open the evening by talking about leadership.
He talked about work.
When Castellano took the stage for January’s CEO Connect, the room looked like Tampa right now.
Exotic cars lined the space. Business leaders filled the seats. The setting suggested momentum. The conversation stayed grounded.
Castellano, managing shareholder at Trenam, spent the evening tracing a leadership philosophy shaped less by ambition than by repetition, responsibility and long-term relationships.
“I was always working,” he said. “You were either in school or you were doing something productive. That was my dad’s mindset.”
That mindset became foundational.
Castellano’s walk-up music underscored the same idea. As The Rolling Stones’ “You Can’t Always Get What You Want” played, he later explained the song had become a refrain in his household when his children were growing up.
It was a reminder that effort matters and outcomes are not guaranteed. Over time, that refrain followed him into his professional life.
One firm, one career
Castellano has spent his entire legal career at Trenam. During the fireside chat, he described the decision plainly.
Staying required patience and commitment. It also meant accepting periods of uncertainty.
“There were moments where I asked myself if this was the right place,” he said. “Every time I came back to the same conclusion. It was.”
Longevity created trust inside the firm. It also shaped his ability to lead.

“I do not think I could have taken on the managing shareholder role without having spent my whole career here,” Castellano said. “People know me. They know how I work.”
That familiarity carried expectations. Leadership did not arrive automatically. It was earned over time.
Castellano acknowledged that longevity also brings risk. Complacency, he said, is something leaders have to actively fight. “It is the beast you keep battling,” he said.
Relationships as responsibility
Castellano described Tampa as a relationship town. In his view, relationships carry obligation as much as opportunity.
“People care about who you are and how you treat them,” he said. “A lot of my clients became friends.”
He acknowledged that closeness requires care. Reputation travels quickly in a market where professional and personal circles overlap. Castellano emphasized the importance of doing work carefully and owning mistakes when they occur.
“You have to be willing to say we missed something or we need to fix it,” he said. “If you make a mistake, it can be very costly for the client.”

“You have to be willing to say we missed something or we need to fix it,” he said. “That is part of maturity.”
Mentorship played a significant role in shaping that perspective. Castellano credited his partners and colleagues for challenging him and demonstrating that strong outcomes can come from different approaches.
“They might handle something differently than I would,” he said. “They still get excellent results.”
That understanding informed how he built teams and how he learned to lead people with different styles.
Leadership learned over time
Castellano framed leadership as something learned through experience rather than instinct. Early in his career, he believed hard work alone would carry him forward.
Over time, he learned that effort needed to be paired with perspective.
“You come out of law school thinking you need to be right all the time,” he said. “Life teaches you that being right is not always the point.”
Family influenced that evolution. Castellano spoke openly about learning from his wife and later from his children.
“My kids are very comfortable telling me I am wrong,” he said. “That teaches you a lot.”

Loss also reshaped how he thinks about leadership. In recent years, Castellano lost his father. His wife lost both of her parents. A close friend and partner passed unexpectedly. Those experiences shifted how he measures success.
“At some point you stop measuring life by the size of your practice,” he said. “You start thinking about whether people are supported.”
That perspective now informs how he leads the firm.
When others spoke about his career during the event, Castellano admitted the praise made him uncomfortable. He described it as part of the job rather than the goal.
Succession as ongoing work
Succession emerged as a central theme during the conversation. Castellano expressed confidence in the next generation of leaders at Trenam while acknowledging the responsibility that comes with transition.
“We have young partners who are engaged and excited,” he said. “That energy matters.”
He emphasized that succession is not a single moment. It is a continuous process that tests culture more than strategy.

“You have to make room and trust people to lead in their own way,” he said.
The firm has expanded leadership roles and practice groups to support that transition. Castellano said learning to step back was part of the work.
“You cannot do everything one way,” he said. “That took time for me to understand.”
A city still defining itself
Castellano’s career has unfolded alongside Tampa’s growth. He has watched the city evolve from a quieter professional market into a region attracting national attention.
“Look around,” he said during the event. “You see how far Tampa has come.”
He serves on boards including ZooTampa and Junior Achievement of Tampa Bay. He views that involvement as stewardship rather than recognition.

“These organizations shape what comes next,” he said.
Growth brings opportunity and pressure. Castellano believes Tampa’s strength lies in maintaining its character while continuing to develop.
“The challenge is preserving what works as the city grows,” he said.
Looking ahead
Castellano plans to continue practicing law. He expects to travel more to visit his children in Chicago and San Francisco. He remains focused on growing Trenam’s Sarasota office and supporting leadership development across the firm.
“I enjoy the work,” he said. “I am not looking to step away from it.”
When asked how he hopes to be remembered, his answer was measured.
“A good lawyer who worked hard,” he said. “A thoughtful and fair person.”
That answer reflected the leadership philosophy that guided the evening. It was built on continuity, responsibility and trust rather than spectacle.
That is the kind of conversation CEO Connect is designed to surface.
TBBW’s January CEO Connect was supported by presenting sponsors FlyUSA, Hyde Park Capital and Storm Shielder, along with nonprofit partner Dogs Inc and host sponsor One Exotics.
