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. Discovering that payers were an important part of the wellness solution, Rhonda researched the insurance market. With those three disciplines coming together to affect wellness, Rhonda created Weltrio.

Amy Bull: Integrative Health & Wellness Coach

I am an Integrative Health & Wellness Coach (trained by Duke Integrative Medicine), who helps people create the time, energy, and balance in their life so they can move confidently towards making an impact in causes they are passionate about in the world.

I have 23 years of experience managing a busy lifestyle, working in the corporate world and running a non-profit organization. After watching many people who were passionate about their causes struggle to find a healthy balance of giving back while also maintaining a happy, healthy life for themselves, I have made my mission to provide space to empower people, so they can feel confident and clear on how they can get involved, make an impact in the world and their communities, but in a way that is sustainable and energizing, instead of draining and exhausting.

In addition to my training at Duke Integrative Medicine, I am trained in Hatha Yoga (200HR Registered Yoga Teacher), and I am a teacher of iRest Yoga Nidra, trained by the Integrative Restoration Institute.

This combination of expertise allows me to hold space for my clients in a mindful, attentive way. Integrative Health Coaching is centered on the idea of the individual becoming more mindful of all aspects of their life and how it impacts their well-being. I believe deeply in the philosophy of Integrative Medicine, and that health and wellness is about treating the whole person, not just the symptoms of disease and illness, and that health is much more complex than just diet and exercise.

Burgandy Brittain: Wellness Program Admin

Burgandy is a medical laboratory scientist trained at Brigham Young University with emphasis in biochemical human nutrition. She is a specialist in lab work and loves to teach people how to get those lab numbers within healthy-range to impress your doctor at your next visit. Her passion is to study how the body can heal itself when properly fueled by the right nutrients at the right times and crushing the out-dated “calories in vs calories out” method with new and cutting edge findings in health science. She has worked in the hospital setting, but prefers getting to work one on one, so that she can truly help people incorporate new habits into their lives on an individual basis; helping them lose weight, reverse disease, and see hugely improved lab values to gain control over their health and life.
