David has over 5+ years of professional public speaking experience within schools, universities and government.
At just 22 years of age, thousands of students have benefited from the authentic, relatable and transformational power of his school programs and books.
From humble beginnings in Perth, Western Australia, Mr Castelanelli has grown to become Australia’s
leading Youth Success Mentor - working with over 150+ schools annually.
He has been voted one of Australia’s National Top 100 Young Leaders and now offers his books and online presentations to an international audience of students.
David has dedicated his life to helping young people achieve their own versions of success and happiness.
David’s career was initially sparked from a suggested YouTube video.
In June 2013, a 15-year-old David came across and watched a YouTube video titled ‘How Bad Do You Want Success?’ - this was his first contact with the world of personal development and success.
As a young student, David became obsessed with reading personal development books, listening to podcasts and attending an array of seminars. This eventually led him to attending international programs in Los Angeles and Hong Kong.
David presented his first motivational speech at his former high school in 2016. Since then, he has visited and worked with over 150 schools in Australia.
