Further allegations have now emerged concerning both ATOS and Checkmat, with Ricardo Vieira being named specifically. Alyssa Mia was once a top child competitor representing Art of Jiu-Jitsu and she has alleged that an unnamed ATOS student s*xually assaulted her when she was just 12 years old. This comes in the wake of recent allegations that led to a massive exodus of ATOS coaches and competitors. At the time of writing, dozens of ATOS affiliate academies have either left or announced plans to leave in the near-future. Alexa Herse is the first to make her allegations against Andre Galvao public, but a recent statement by now-former ATOS black belt Rose Miller referenced ‘girls’ and said that she is ‘supporting them in sharing when they’re ready.‘
For Mia, that incident isn’t the only one that she’s now shared publicly. She also talks about another series of allegations dated to when she was 16; against another BJJ black belt that, until now, has also remained unnamed. She has now decided to speak out again though, publicly naming Checkmat co-founder Ricardo Vieira as the alleged perpetrator. There’s no official comment made by the organization at the time of writing, but they have only just announced the removal of fellow co-founder Leandro Vieira after he was accused of abuse and misconduct.
Alyssia Mia actually first came forward with her story in a post to her official Instagram account in 2021:
Mia reshared this recently and for the very first time, she decided to publicly name Ricardo Vieira. She also accused the parents of several young competitors at Art of Jiu-Jitsu, including the Ruotolo brothers’ mother, of ‘sl*t shaming’ her in statements made about her. Prior to 2020, AOJ was closely affiliated with ATOS and this alleged incident would be dated at around 2012 based on the timeline given by Mia. She states that she actually approached both Andre Galvao and Angelica Galvao with the information but ‘they did nothing to remove him, he stayed’. This is eerily similar to Herse’s claims of reporting her experiences to Angelica too.

When this began to circulate on social media, an anonymous Reddit account shared a comment that was structured to imply that the account belonged to Mia too. Much of the story remained the same as her Instagram stories, but she also shared some more information about the circumstances surrounding her exit from AOJ:
