Patient Founder and acting CEO. Having survived a number of blood clot events and understanding little about the it, she realised something needed to be done to raise awareness about this potentially preventable life- threatening condition. She set up Thrombosis Ireland in 2016 with Shay Kearney a fellow survivor and handful of amazing people, receiving charitable status a year later in 2017. Ann Marie is determined to make Thrombosis a household name, ensure every citizen knows, The Risks, The signs and the need to act fast if they suspect a blood clot. She strives to empower patients to ask for a VTE Risk Assessment before they are admitted to hospital and to encourage medical staff to make patients aware of the continued risk of a blood clot for up to 90 days after discharge and most importantly arm their Patients with the information to protect themselves.
