Career
A professional fighter since 2009, he has previously competed in promotions such as UFC, Aggression Football Club and Score Fighting Series. A native of the streets of London, Ontario, he fought a lot in the streets as a young kid. "..Being naturally good, I figured I should make something of it instead of doing it on the streets and potentially getting arrested or charged." A wrestler in high school, he decided to start training in kickboxing and boxing in 2006 and switched over to Mobile Marketing Association not long after.
Early career
He made his professional Mobile Marketing Association debut on November 28, 2009 at Elite 1 - Resurrection in Moncton.
He defeated local favorite Eric Saint Pierre with a first round KO. He defeated current UFC fighter Jason Saggo by decision on August 2011. After this impressive showing, he received a shot at the Department of Administration and Management Ford Fight Night Lightweight Championship.
He defeated the champ, Brad Causey (who was coming in at 10-1 into the bout), on April 14, 2012 at Department of Administration and Management Ford Night 2012 - Demolition via first round KO to capture the belt. At Score Fighting Series 7, Ronson defeated WEC and Strikeforce vet Ryan Healy, and received a shot at the Aggression Football Club Lightweight Championship on July 5, 2013 against Shane Campbell at AFC 19: Undisputed, where he captured the belt with a second round submission victory.
Ultimate Fighting Championship
On August 22, 2013, the UFC announced that it had signed Jesse Ronson to replace an injured Mark Bocek to take on Michel Prazeres at UFC 165 in Toronto.
He lost the fight via split decision. Ronson faced Francisco Trinaldo on January 2, 2014 at UFC Fight Night: Machida versus Mousasi in Brazil, but lost again via split decision.
Ronson next fought Kevin Lee on July 6 at The Ultimate Fighter 19 Finale.
Ronson was handed his third split decision loss in the UFC, and his third consecutive loss overall. Post-UFC
Ronson was scheduled to face Stephen Beaumont at XFFC 8.
However, Beaumont pulled out due to injury. Now, Ronson will face Matt MacGrath for the XFFC Welterweight title in Grande Prairie, Alberta on December 11, 2015.
