Meet Sally

I’m Sally — a Nutritional Therapy Practitioner, the face behind Rhiza, and a life-long lover of food. My heart is for wading through conflicting information in pursuit of truth, as I work to build a vibrant life, in line with God’s design. My husband and I live in Boise, Idaho where we enjoy hiking, biking, skiing, snowboarding, swimming, and floating down the river. Just about anything active and outside. When I’m not working with clients or running around outside, you’ll likely find me in the kitchen, at coffee with a friend, or tucked behind a good book.

What is Nutritional Therapy?

Nutritional Therapy is a holistic, root-cause approach to wellness that focuses on restoring health and balance through nutrient-dense whole foods, individualized nutrition planning, and supportive lifestyle adjustments.

Developed by practitioners trained through the Nutritional Therapy Association (NTA), this approach emphasizes that each body is unique—requiring a bio-individual plan rather than one-size-fits-all advice

Nutritional Therapy Is Not:

  • A one-size-fits-all diet or rigid meal plan

  • A branded cleanse or supplement program

  • A quick fix or symptom-chasing approach

  • A substitute for medical diagnosis or treatment

  • Judgmental or perfection-based—it's flexible, supportive, and personalized

  • "The healing I've received from the work we've done together is hard to put into words and I am so thankful. Your gentle and steady guidance when it got hard was always soothing, grounding, and orienting. I'm glad to know you're out there doing this work and that I can come back to you whenever I need."

  • "I love that Rhiza takes such a holistic and food-based approach. Sally gave me some suggestions on supplements for short-term use and then gave me great suggestions for changes I could make to my diet. I noticed positive changes towards my goals just a few days in!"

  • "I would recommend HTMA to everyone - I wish I had known about it earlier! It gave me such a clear understanding of where I was struggling and what my body needs at a cellular level to thrive. Everything was clear and understandable, and the actionable steps didn't require me to spend hundreds of dollars on more supplements (I love the whole food approach!) which I was very thankful for."

My husband and I both did HTMA tests with her and it was awesome to be walked through our results together so that we can support one another in the ways needed.

  • "I did HTMA testing with Sally and it helped show some insight on the deeper underlying issues in my menstrual cycles. The most valuable thing was working with Sally specifically. She interpreted the results in a very matter of fact and insightful way. Sally looked very closely at my medical history and developed a very individualized and informed nutritional protocol for me. I would highly recommend working with Sally, especially for anyone that wants lifestyle changes and not just bandaid fixes. She is very knowledgeable and has so much to offer!"
