S. Sëan Tretheway was born in Inglewood, California. When he was seven, he caught the magic bug and performed as Sëando the Magician, charging fifty cents a show.
At the age of twenty he helped build a ferro-cement sailboat with his sister and brother-in-law, Roxanne and Jeannot, in their backyard, which they then sailed from Los Angeles to Tahiti.
After six months island hopping in the South Pacific, Sëan moved on to New Zealand, where he spent another six months hitch-hiking the North Island.
In 1977, Sëan came to Australia to continue his adventure.
In 1982, he found Noosa Heads, Queensland and realized that his childhood hobby as magician could earn him a fulltime living. Sëan has been entertaining residents and visitors to Noosa for twenty-five years. During this time he entertained thousands of visitors from all over the world including celebrities such as Hugh Jackman, Geoffrey Rush, Kylie Minogue and Barry Humphries (Dame Edna Everage). He has also been flown all over Australia for corporate functions and television spots, as well as a tour in Japan.
For seven years, Sëan produced and presented a radio program for Noosa Community Radio which focused on the local music scene.
Sëan has two sons, Alex and James who are hip-hop musicians known as Babek and Kudos.
In 2005, Sëan decided to pursue another dream and write a book, which he completed the first draft in thirty days by following a unique system devised by Chris Baty (www.nanowrimo.com).
Sëan spent the next three years rewriting and editing the book, shaping and creating the final version of The Roadless Traveller, which was released in early February, 2008.
In 2012, Sëan published his second book, Beyond The Road, a sequel to The Roadless Traveller. Though this book is fiction and continues the adventures of Jack and Blazer, Sëan used his own experiences of sailing the South Pacific to shape the story.
Since then, Sëan continues to practice his creative art through performing sleight of hand close up magic around the world and writing in between the lines.
In 2017 he published the third book in the Roadless Traveller series, "The Road to the Heart" which follows the adventures of Hollie and Cynthia from L.A. to India.
Sëan has recently published his latest book, "Yan and Raul" - The story of a man, a woman ... and a talking dog! He also has a podcast called The Roadless Traveller Podcast which can be found on most Podcast catchers as well as trtpod.com
