Avenge Fitness founder and CEO Teresa Oxford has an extensive history in the fitness industry. She began participating in bodybuilding competitions at the age of 19, gaining multiple titles from various federations and earning her pro status early in her career. Years later in 2018, with her three boys cheering her on proudly, she accepted the title of 3rd in the world at Worlds in Las Vegas. 

She began her career in the nursing field, but her passion remained in fitness. Over the years, she developed an expansive network in the photography and fighting industries. Throughout her career she has worked as a writer and cover model for various fitness magazines. She was an integral part of a successful franchise model that grew to hundreds of locations worldwide. She is an author and has a publicity tour set for her book in 2023. 

Teresa's vision for Avenge Fitness Clothing was to take the most successful aspects in each of her past endeavors and synthesize them into something new and innovative. Her goal was to create an inclusive female-focused fitness brand of the highest quality. She has created a corporate culture focused on customer service, attention to detail, and teamwork.

Consulting Avenge Fitness CTO Matthew Ramadanovic has a long career in IT. He founded an IT company in 2001 where he remains active. His focus has been largely in finance where he specializes in process automation and programatically linking disparate systems. Teresa Oxford recognized that his specialty would provide mechanisms for increasing efficiency in ways not normally applied to the fitness apparel or online coaching industries. His experience has provided a trusted sanity check on the tech spend of Avenge Fitness.
