Dave Marshall, Owner and Founder
Dave founded the retreat alongside Wendy to continue a lifelong
interest in personal fitness. Originally from Oregon, Dave began intensive physical training at the age of 18 and began professional personal training several years later to supplement his income
first as a deep-sea diver and underwater welder, then as a commercial pilot.
In 1990, Dave founded and built one of the largest cable & telecommunications marketing companies in
Australia and the U.S. But this financial success came at a physical cost, causing him to increase his weight from 160 lbs. to 240 lbs., largely the result of the excesses of corporate
Dave decided to reset his lifestyle at age 40 in 2000 to regain a balance in his life. He sold his firm and began traveling the world seeking health, fitness and martial arts
training at various retreats and camps.
In addition to regaining his peak physique, Dave recognized that raw and detox retreats he discovered overseas could be adapted for a western
clientele to include fitness regimens and 'going forward' programming. He developed the Detox Oasis signature retreats, with guidance from Dr. Matthew Andry, to blend these various training and
weight loss methods into single- and multi-week programs.
