Hi, I’m Dr. Christina O’Brien—functional medicine doctor, board-certified clinical nutritionist, and unapologetically obsessed with helping women balance their hormones, reclaim their brainpower, and feel at home in their bodies again. I’ve spent the last two decades guiding brilliant, driven women through the rollercoaster of perimenopause, gut dysfunction, anxiety, autoimmune conditions, burnout, and the “why do I feel like I’m falling apart even though my labs are normal?” chapter of life.

I specialize in the connection between hormones and brain health, blending clinical neurology, genetics, organic acid testing, and lifestyle-based healing inside my private wellness center in Lewisville, TX and my growing online ecosystem. My approach is data-driven, heart-forward, and rooted in the belief that women deserve care that’s both deeply scientific and deeply human.

As the founder of Complete Health & Wellness, Optimal Health and Wellness, and the creator of The Balanced Hormone Blueprint, I’m here to raise the vibration of humanity starting with the women who are holding everyone else together. My mission is to build a future where hormone health, nervous system regulation, and functional medicine are the norm, not the exception.
