Rhonda is a certified nutritionist, has a BSN in Nursing from Utah Valley University, and has completed graduate work at both Georgetown and Duke University in Integrative Medicine. She is a Duke-certified health coach. Rhonda is also the mother of five children. She started the path towards Weltrio when her pediatrician put two of her daughters on preventative antibiotics for 6 months. Hoping there was a better way, she started studying nutrition and quickly moved into medicine with a focus on Integrative Medicine.

With those three disciplines coming together to affect wellness, Rhonda created Weltrio.
