Improve Your Health

Personalized action plan that addresses the root cause — not just the symptoms.

At-Home Health Testing

Understanding what's happening inside your body is one of the most powerful steps you can take toward lasting health. I recommend SiPhox Health — an innovative at-home blood biomarker testing service that puts clinical-grade insights in the palm of your hand, without ever setting foot in a lab.

No Needles. No Lab Visits.

SiPhox's proprietary EasyDraw kit collects a small blood sample from your upper arm in just 5 minutes — completely painless. Mail it back with pre-paid shipping and receive your results in 7–10 days.

Meet Sai — Your 24/7 AI Health Assistant

Every SiPhox membership includes access to Sai, a personal AI Health Advisor built into the dashboard. Available 24/7, Sai analyzes your biomarker results and lab data to deliver personalized insights and an actionable health plan.

Personalized Action Plan

Results come with a detailed plan tied to your specific biomarkers — dietary recommendations, lifestyle adjustments, and supplement optimization aligned with holistic nutrition principles.

🎓
Certified Holistic Functional Nutrition Counselor

Hi, I'm Maggie.

I'm a Certified Holistic Functional Nutrition Counselor with a Bachelor's degree in Psychology & Nutrition from the University of Arizona — where I also competed as a collegiate triathlete, including the U.S. Collegiate Triathlon Championships.

I believe deeply in the body's ability to heal when given the right tools. My whole-food-first approach focuses on gut health, reducing inflammation, and building the daily habits that lead to lasting transformation.

I held an executive leadership role in the sports nutrition industry at a company I co-founded, working with endurance and Olympic athletes to develop and market performance-focused nutritional products.

Beyond counseling, one of my most meaningful projects included launching a Christian Community Garden to provide fresh, nutritious food to the underserved in our local community — the project model was studied by Cardinal Peter Turkson of the Pontifical Council for Justice and Peace under Pope Francis.

Throughout my life, my greatest fulfillment has come from being a Mom and as a servant leader in the communities where I have lived.

I am profoundly grateful for the gift of my Christian roots, my relationship with Jesus Christ, and my family — all of which are my greatest joy and my inspiration.
