ABOUT THE FOUNDER

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.

MY STORY

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.

HOW I PRACTICE

My approach, in plain terms.

Listen first.
Symptoms are signals, not inconveniences. Before any test or prescription, I want to understand what your body is actually telling us.
Test thoroughly.
Comprehensive baseline labs through Quest Diagnostics, not just a single TSH or a basic hormone panel. Specialty testing when it adds clinical clarity, never as a default.
Treat the person, not the panel.
Labs are guideposts, not diagnoses. Every treatment plan is built around your symptoms, your history, your goals, and what's medically appropriate for you.
Adjust as you go.
Hormone care, weight care, metabolic care, none of it is "set it and forget it." Real partnership means we adjust the plan as your labs and life evolve.
Be honest about scope.
Not every patient qualifies for every therapy. I'd rather tell you that up front than promise something I can't deliver.

WHAT TO EXPECT

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."
