Our retreats are located on the Marshall’s private family farm, Elk Ridge Ranch in the Hoosier National Forest near French Lick, Indiana.   French Lick is well-known for it’s two historic hotels with world class spas and mineral waters.  Cleansing retreats “sprung up” in French Lick around the turn of the century.  Our location is about 110 miles from Indianapolis, International Airport (IND) and Louisville Airport (SDF).

Our Founders

DAVE MARSHALLOwner 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 entertaining.

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.

Dave also authored his first book in 2012, Marshall Law: Raw Foods to Red Meats. His book was written for his clients and is full of recipes from detox to meal packing muscle foods. Check it out at the link below!
