One of our most inspiring, professional and experienced inspirators is Patrick McKeown with this Oxygen Advantage (OA) program.

Patrick was educated by Drs Buteyko and transformed Buteyko breathing into his own method.Kim, founder of n-ice world, is a Master instructor OA and the method is integrated in her teachings.

So the BreathFluencer modules OA is also integrated but if you want to start with some source material you can buy several courses here.

This February 2024 I will travel to Spain to again learn more from Patrick and another colleague. Always nice to be inspired again.
And trust this will become part of TBF Academy as well.

Also I am curious whom I will meet this days. Last time in Belfast Thermalist Susana Soeberg was my co-student, she integrates the OA wisdom in her method as well. Soon I will also start sessions honouring her principle. Check events to see the dates.
