Mary first appeared on ‘Operation Transformation’ in 2018 and became a fan favorite on the RTE program. The show focuses on helping Irish people lead healthier lives and achieve their weight loss goals. Mary was affectionately referred to as “an absolute gem” by the Operation Transformation team after her passing. In an emotional social media post, they extended their “deepest sympathies to the family and friends of our 2018 Leader”. They continued, “Mary was an absolute delight; it was an honour and privilege to know her. May she rest in peace.”

The tragic news sent shockwaves across social media. Mary was described as an “amazing person”, a “natural teacher,” and an “inspirational leader”.
