Dr. Heidi S. Flagg, NCMP

A menopause expert on your side.

Hello! I’m Dr. Flagg, and I care about what’s keeping you up at night.

I’ve been an OB-GYN for nearly 30 years. I’ve delivered babies during hurricanes, trained with top hospitals, and built a thriving practice in New York City. But these days, the question I keep asking my patients (and myself!) isn’t just: “What’s wrong?”

It's:

Hello! I’m Dr. Flagg, and I care about what’s keeping you up at night.

It's:

What are you afraid of?

Fear runs quietly through so many of our visits - especially during perimenopause, menopause, and so many changes we don’t feel prepared for. I hear responses like:

Is this normal or am I losing my mind?
Is hormone therapy safe?
Is it too late?

And maybe most of all:

Will I ever feel like myself again?

That’s what I’m here for.
It’s why I started FLUXX.

I know what it feels like to want answers but end up with more questions.

Over the years, I’ve met so many women sitting across from me, each with their own story - but sharing the same look in their eyes:

Over the years, I’ve met so many women sitting across from me, each with their own story - but sharing the same look in their eyes:

Is anyone actually hearing me?

Some walk in confident, ready to start hormone therapy.
Others are hesitant, overwhelmed by risks they’ve read about or confused by scattered advice.
Some are curious, trying to stay ahead of changes they’re just beginning to notice.
Some are skeptical, leaning more into what feels “natural,” unsure if hormone therapy fits their values.

I’ve seen you - confident professionals, tired moms, women who’ve tried everything and are still waiting for relief.
I’ve met you - crying. Whispering. Angry. Hopeful.
And I’ve learned to ask:

“What matters most to you right now?”

Then we go from there - together - because every one of you deserves clarity, time, and a plan that fits your body and your lifestyle. Whether you sit down with me or use FLUXX, I want you to feel supported, not sold to. Heard, not hurried.

What I believe - and what FLUXX helps make possible.

I’ve seen what happens when women get the right treatment, and what happens when they don’t.

I believe hormone therapy, when done right, can be life-changing.
I believe in shared decision-making: because the best care plans come from conversations, not quick fixes.
I believe insurance shouldn’t be a barrier to relief.
And I believe in science, not sales.

That’s why FLUXX doesn’t sell hormones, and we’re not here to push a one-size-fits-all solution.

We’re here to give you power:

This platform was designed to help you walk into your next appointment saying:

“I know what I’m experiencing. I know what might help. And I’m ready to talk about it.”

Here’s a bit more about what I bring to the table:

I’m a fourth-generation physician and the first woman in my family to become an MD.
I’ve delivered babies in blackouts and counseled women through every stage of their reproductive lives.

I co-founded Spring OB/GYN in 2002 with my friend and colleague, Dr. Brina Maldonado.
I serve on the HL Snyder Foundation to fund women’s health research at top institutions.
I've taught at NYU Grossman School of Medicine Department of Obstetrics & Gynecology.
I’ve run half marathons with Every Mother Counts and presented on maternal mortality in Haiti.
I’m also a mother of two, and I live in New York City with my husband.

I’m proud of the credentials I’ve earned. But what matters most to me is how I show up for the women who walk through my door: present, prepared, and completely on your team.
