Like Hugh, Maryanne left school with few formal qualifications. However, Hugh saw the qualities and potential in his eldest daughter that would lead to Maryanne working closely by her father’s side for over 25 years. During this time, she would progress from managing his farming office, Kilmacrennan Livestock, through to being the Chief Executive of the Green & McCahill Group and later the Hugh Green Group before retiring in 2012.
In 1998 Hugh and Maryanne established the Hugh Green Charitable Trust later to be renamed the Hugh Green Foundation. During the 13 years she spent as a founding trustee of the Hugh Green Charitable Trust, Maryanne made many contacts in the philanthropic community and developed a passion for what her dad would call “lending a helping hand – a hand up not a hand out”.
