Receiving CFX’s Lifetime Achievement Award is the latest accolade for recently-retired Carollo, a longtime champion of rural broadband. When inducted to the Cable TV Pioneers in 2025, Carollo, his father and grandfather—who founded Sweetwater Cable Television in 1956—became the industry’s first three-generation Pioneers.
Carollo grew up learning the family business. “I remember as a little kid going down with my dad to change tubes for the amplifiers,” he recalls. “Through high school, every one of my siblings worked in the company. We did everything. We dug the ditches and we did the installs and learned it all.”
A career in cable seemed inevitable, but instead Carollo became a marine biologist and worked as an aquarist at Sea World in San Diego and the Oregon Coast Aquarium. The untimely death of his brother, his grandfather’s impending retirement and the advent of digital cable convinced Carollo to rejoin Sweetwater in 1999.
“At that point, we were planning on selling the system,” Carollo says. But his father guaranteed him five years’ worth of work. “We started putting in fiber in 2001, tied our two towns together. Digital cable came out, and we went from 65 channels to several hundred. I was involved with all of that. When you’re a small business you do it all.”
His mission became learning everything he could about all facets of the business. And his industry knowledge grew with each advancement, just like high-speed internet. “I was just a marine biologist trying to figure it out, through stupidity more than anything else. To be honest, I didn’t know any better that it couldn’t be done, so we just did it,” Carollo says.
As Sweetwater grew, Carollo recognized its ability to keep pace with technological advances was limited. “I could see what was coming down the pike—demands and needs and all the things coming in with fiber—and knew it was time to let somebody with greater resources take it on. It was going to be too much for us to be able to do what has to be done with the overbuild of fiber,” Carollo says.
In 2017, Sweetwater was sold to All West. “I thought that was the end of my career.” But All West kept him on.
“After the acquisition, Marty had a number of different roles with us. He ended up in our government relationships group, which was fantastic for us. He was well known. He had the right contacts—not only state representatives but federal, on the Senate and House side. It was a natural fit for him,” says retired All West CEO Matt Weller. “He’s genuinely a good guy. He honestly cares, which is what comes across, and what helps him make connections with people.”
Before retiring earlier this year, Carollo had served on the Wyoming Cable Association Board for 14 years and was appointed to the ACA Cable Connects Board in 2023.
“He was a one-man advocate for the western half of the United States, on behalf of all things rural telecommunications, rural independent operators,” says Patricia Jo Boyers, ACA Chair and President/CEO of Boycom Cable. “I don’t know anybody that rolls their sleeves up and jumps in, whatever it is and whatever it takes, like he does. If anybody deserves to ride off into the sunset on a well-bred horse, it’s Marty.”
