For more than 30 years, Diana has been a well respected speaker, author and coach, teaching the Nightingale philosophy to audiences around the world. In recent times, Diana has answered the call to share more quality time with a more intimate audience, resulting in the Nightingale Retreat, where a limited group of participants gather with, The First Lady of Transformation, in retreat style learning in select resorts around the world.

The ORIGINAL 1956 GOLD RECORD RECORDING, written and recorded by the Dean of Motivation, Earl Nightingale.
