Sami Callihan has worked for several independent promotions throughout the United States. He found the most success in Combat Zone Wrestling (CZW) and Major League Wrestling (MLW), but has also wrestled for Dragon Gate USA, Evolve, Ring of Honor, Pro Wrestling Guerrilla, Full Impact Pro, and All American Wrestling.
In CZW, he held the CZW Iron Man Championship, the CZW Ultraviolent Underground Championship, and the CZW World Junior Heavyweight Championship, and won the 2012 Best of the Best tournament. He is also known for his stint with WWE from 2013 to 2015, appearing in NXT under the ring name Solomon Crowe.
He also runs an independent wrestling promotion called The Wrestling Revolver. During a long interview with Wrestling Inc, Callihan talked about the status of his Impact Wrestling contract: “I’m signed with Impact Wrestling until next December  but that’s not on my mind right now.
My mind is being one of the full forces behind saving Impact Wrestling and I think they’ve done that. I think everyone’s coined this term that Impact Wrestling is hard to kill. We’re not gonna insult anyone’s intelligence by looking back at the past and saying the past was good. No, there was a lot in the past and this company was in sh*t shape."
