Mariella began her career as a model and a dancer for several television programs. But her passion had always been sports and so she decided to become a bikini competitor.
She won her IFBB pro league card at the Olympia Amateur in Liverpool, after having placed 4th at the Arnold Classic USA, her first competition in the US.
She then began her professional career in 2017, placing 6th at the Omaha Pro and 2nd two weeks later at the Prestige Crystal cup, missing a qualification for the 2017 Olympia by only ONE point!
Through her hard work and dedication in 2018 she won 3 consecutive competitions, the Galaxy Pro, San Marino Pro and the Veronica Gallegro Classic, finally winning her qualification to compete in this year’s Ms. Olympia.
