Hi, I'm Michele.
Board-certified Physician Assistant at Core Function Health — and the practitioner I wish my own patients had years before they found me.


Medicine that actually listens.
I'm Michele Missakian, a Physician Assistant and the founder of Core Function Health. After years inside traditional medicine watching women get dismissed, rushed, and handed prescriptions without answers, I built the kind of practice I wished existed: one that listens, looks at the full picture, and treats the root cause.
I specialize in bioidentical hormone replacement, functional medicine, and medical weight loss for women navigating perimenopause, menopause, and the in-between, and for men who want to age well, not just age. My approach combines evidence-based hormone optimization with real labs, real time, and real conversation.
More about my training, care philosophy, and what makes the practice different is below.
My approach, in plain terms.
Where I trained, what I'm part of.
Continuing education is a permanent part of how I practice, particularly in hormone health, functional medicine, and longevity care.
Core Function Health operates as a Physician Assistant Corporation under the medical supervision of a licensed California physician.
What makes Core Function Health different.
Our clinical model prioritizes depth, clarity, and unhurried clinical interaction over insurance check-boxes.
Unhurried visits.
Sixty minutes for your initial consultation. Time to actually be heard, tell your story, and map out a pathway together.
Cash-pay clarity.
No insurance hoops, no surprise bills, and no third-party companies dictating what quality of care or tests you are allowed to receive.
Real labs, real reviews.
Comprehensive baseline testing and a dedicated, deep-dive visit to walk you through every marker, not a rushed call about confusing reference ranges.
Bioidentical, evidence-based.
Hormone therapy backed by current medical research and tailored specifically to your unique physiology, not a static, one-size-fits-all protocol.
Ongoing partnership.
Memberships and care programs designed deliberately for the long game, because real metabolic and hormone balance is not a single-visit fix.
"My job isn't to hand you a prescription and hope. It's to help you understand what your body is doing, and walk with you while we figure out what works."
Ready when you are.
