MIAMI — Conwell & Steen isn’t a law firm, but a pair of talented brothers from Cleveland, Ohio, who will be part of Friday night’s boxing card at Buffalo Run Casino & Resort.

Charles Conwell Jr. — a member of the 2016 USA Olympic boxing team — makes his professional debut, facing Jeremiah Page (3-3, 2 KOs) of Andover, Kansas, in a four-round middleweight fight that has been tabbed as the co-feature.

Conwell’s brother, Isaiah Steen battles Larry Smith in a six-round middleweight clash.

“I am proud; I am happy to be where I’m at right now, fighting on the same card as my brother for his pro debut, ” Steen said. “I am excited.”

Steen is 6-0 with five of the wins coming by knockout.

By comparison, the veteran Smith has 43 fights under his belt. He’s got 10 wins (seven by knockout) and one draw.

Conwell is the newest member of the Four State Franchise — joining Trey Lippe-Morrison, Ivan Baranchyk, Dillon Cook, Jesse Cook and Jarrett Rouse.

“For us to pick up Charles Conwell, it was just a huge score,” promoter Tony Holden said. “He had the opportunity to sign with every single promoter.”

But seeing Baranchyk in action and the crowd reaction on TV helped sway Conwell to join the 4SF.

“A lot of times when you build a fighter, you are on the undercard of mega-fights, but you are in a half-empty arena and come out early, Olympian or not,” Holden said. “They recognize they can come in here and have a fan base and have a family; a support system. That’s one of the things that sold them. That’s what makes me proud of our fans.”

Holden and longtime friend Lou DiBella joined forces to land Conwell.

The 2016 Ohio Amateur Athlete of the Year, Conwell has won 11 national championships as an amateur.

He admits he has the normal first-time butterflies.

“I have butterflies … I am just anxious, but have no concerns,” Colwell said. “I feel this is the right thing to do for my career.

“We’ve been working on everything, timing, speed, power … I am ready.”
