From a young age, Ramir Mosqueda was captivated by martial arts, inspired by the action films of the 1970s and '80s. While his first formal training experience fell short of expectations, everything changed at age 12 when a friend introduced him to Grandmaster Jim Buhisan. The positive, family-oriented environment created by GM Jim reignited Ramir’s passion and set him on a lifelong martial arts journey.

Ramir earned his first black belt in 1989 and soon after set his sights on becoming a World Champion. Competing under the National Blackbelt League (NBL) throughout the early '90s, he went on to become a 4-time NBL World Sport Karate Champion and an Overall NBL World Champion, qualifying for the World Championships five years in a row. He retired from competition in 1996 and transitioned into teaching, eventually becoming a school partner with his original instructor, GM Buhisan.

Today, Ramir Mosqueda serves as the Owner and Master Instructor at United Academy of Martial Arts. He considers this role his most rewarding yet. His mission is to inspire and guide students to become the best versions of themselves—both inside and outside the studio. In collaboration with martial arts leaders nationwide, Ramir has helped shape a modern, life-skills-focused self-defense curriculum that empowers students to reach their full potential.

Dan Southworth, a lifelong friend of Master Ramir Mosqueda, is one of the newest and most dynamic instructors at United Academy of Martial Arts. Their friendship began in middle school, where they trained together in Karate, Tae Kwon Do, and wrestling—laying the foundation for a lifelong journey in martial arts and performance.

Dan’s path in martial arts led him to win multiple championships before transitioning into a highly successful career in the entertainment industry as a professional actor, stuntman, and martial arts trainer. His dedication to constant growth and mastery has earned him the title of Martial Arts Master, both on and off screen.

Dan is best known for his role as the Red “Quantum” Ranger in the internationally beloved Power Rangers: Time Force, and as Vergil in the hit video game series Devil May Cry, including the award-winning Devil May Cry 5. Fans also recognize him as Kenshi in Mortal Kombat: Legacy II on HBO Max. His on-screen presence extends to guest roles in hit TV series such as NCIS: LA, 9-1-1: Lone Star, The Rookie, and more.

Beyond acting, Dan has made a major impact behind the scenes—training actors and stunt performers in martial arts and physical performance, as well as coordinating stunts for film, television, commercials, and video games.
