Delfin International

Transforming the Way the World Envisions & Creates the Future

DELFIN International Inc was founded in October of 1995 by Leslie Fieger for the purpose of marketing personal empowerment products.

The initial product was a book and a set of audio cassettes that was originally entitled The DELFIN System. It was inspired by and based on Charles Haanel’s seminal self-study program called The Master Key System. Over the years, that product also became known as The DELFIN Knowledge System. Today that original course is now a book called The Master Key and is sold through Lulu, Amazon and other online book retailers.

The second product introduced was live seminars. The first seminar was held in December of 1995 in Long Beach, California. Since then, Leslie has been on stages all around the world. His message of empowerment, conscious creation and the prosperity paradigm has been heard by more than a million people around the world.

The DELFIN Seminars changed the whole concept of personal empowerment seminars. The multi-sensory, multi-media high-tech environments created for these seminars enabled attendees to not only receive, process and retain more information than ever before, but, more importantly, to make a real and permanent personal transformation from creature consciousness to creator consciousness.

The latest Delfin Seminar created by Leslie is called Metamorphosis. The Metamorphosis Seminar has been created to provide you with that truly transformative experience which will forever impact you and propel you to the next level of self-actualization.

The revolutionary new experiential environment created for Metamorphosis is a step the beyond the ground breaking multi-media, multi-sensory of the original Delfin Seminars. It is also a multi-dimensional experience unlike anything you may have experienced before.

After, the original Delfin System (now called The Master Key), Leslie went on to write three new books, entitled The Initiation, The Journey and The Quest, which collectively became known as The DELFIN Trilogy. Each of these books was supplemented by audio CDs. The DELFIN Trilogy has been called “the most comprehensive personal empowerment product ever created”.

The DELFIN material has been used by tens of thousands of people all around the world to craft successful and fulfilling lives. The DELFIN Trilogy is now available as a single 724 page book and 18 hours of MP3 audio. See this page. 

Leslie’s other books include Your Prosperity Paradigm, which has over 100,000 readers.

DELFIN International product sales have exceeded $80 million.
