Meet the Team

“Breathing is an extraordinary resource with life-changing potential, and it’s simple, free and available to everyone.”

Patrick grew up with debilitating asthma. In 1998, he found an article in an Irish newspaper about the Buteyko breathing method. He tried the exercise to unblock his nose and was struck by how well it worked. Since then, he has become a leading expert on breathing, and an advocate for its health benefits.

Patrick lives with his wife Sinead and daughter Lauren in a remote cottage in the West of Ireland where he enjoys a simple life, making time every day to walk in nature.

“I’m passionate about sharing Patrick’s teachings, having understood the remarkable health benefits.”
