iHeartMedia Miami is keeping one of South Florida radio’s most familiar voices right where listeners expect to hear him. The company announced that it has reached a new long-term agreement with Paul Castronovo, extending his tenure as morning host on Big 105.9. The multi-year deal ensures The Paul Castronovo Show will continue airing live weekday mornings from 6–10 a.m. ET on the classic rock outlet.
Castronovo has been the centerpiece of Big 105.9’s morning lineup for decades and remains one of the market’s most durable ratings performers. His show blends humor, pop culture, sports talk, and distinctly South Florida sensibilities, a formula that has helped him maintain a loyal audience across multiple generations of listeners.
“iHeart just signed me on for another five years,” Castronovo said in a statement. “Either they really love me — or they lost a bet. Honestly, I’ve got the best job in South Florida. Every morning, I get to laugh with my friends, and they actually pay me for it. This new deal will mark 47 years of doing radio in South Florida, and that’s just wild.”
The agreement further cements Castronovo’s status as one of the longest-running radio personalities in the Miami-Fort Lauderdale market. His career spans more than four decades and includes previous stops at WSHE and WZTA before he settled in at Big 105.9 nearly 25 years ago. Along the way, he has become one of the region’s most recognizable on-air figures.
iHeartMedia Miami/Fort Lauderdale Market President Shari Gonzalez said Castronovo’s connection to the audience played a major role in the extension.
“Paul brings a distinctive mix of personality and an authentic community connection that truly resonates with his loyal listeners and advertisers,” Gonzalez said. “We’re thrilled to have Paul continue his incredible radio run in Miami and keep his iconic morning show on Big 105.9 for years to come.”
Beyond his on-air work, Castronovo has built a reputation for community involvement throughout South Florida. He has helped generate more than two million pounds of food donations for Farm Share and has held leadership roles with the Miami Dolphins Foundation, including serving as co-chair of Fins Weekend. He also sits on the board of directors for the Guy Harvey Ocean Foundation.
