the rht story
Rebel Health Tribe (RHT) was founded in late 2014 after co-founders Michael Roesslein and Joe Rignola met in an online forum for Functional Diagnostic Nutrition Practitioners (FDN-P), an intensive training program they’d recently completed.

The story (which you can catch in full detail HERE on the podcast) goes a little something like this…
