Praise From our clients

  • "For years, I battled with acne that left me feeling insecure. After my comprehensive functional bloodwork and GI Map screening with Eighteen Diagnostics, I learned about my gut health’s connection to my skin. Simone’s recommendations were not just skin-deep; they transformed my overall well-being. My skin has cleared up, and I feel radiant again!"

After implementing your suggestions, my bloating has significantly decreased, and I finally have regular digestion. It’s been such a relief to feel comfortable in my body again. You’re the best!"

  • "Navigating PCOS has been a journey, and I often felt like I was alone in my struggles. Working with Simone has been transformative. The Stress and Hormone Panel helped pinpoint my hormonal imbalances, and the insights I received led to a personalized protocol that truly worked. My cycles are more regular now, and I feel more in control of my body. I wish I had started this journey sooner!"
