For Women Who Refuse to Feel "Fine"

For Women Who Refuse to Feel “Fine”

For Women Who Refuse to Feel "Fine"

Personalized, physician-led care for women who are intentional about how they live and how they age.

You’re capable. You show up. You take care of everyone else. But somewhere along the way, you stopped feeling like yourself.

  • Waking at 2 a.m. with a racing mind.

  • Weight that won’t budge despite your best efforts.

  • Brain fog and fatigue stalling your day.

  • Being told your labs are “normal” when you feel anything but.

This is not a failure of will. It’s physiology. We connect the dots between your hormones, metabolism, and nervous system to get you back in the driver’s seat of your health.

The Vitality Intake Visit

The Vitality Intake Visit

Every partnership at VitalityMD begins with an extensive two-part visit designed to create absolute clarity around your health and define your best next steps.

Visit 01 | The Synthesis A one hour office visit for an in-depth clinical consultation including Vitality Mind-Body Phenotyping and comprehensive health overview, as well as optional lab testing (70+ biomarkers) through your insurance or review of your metabolic and hormone lab panels. We map out your health challenges and goals and identify meaningful patterns across your hormones, metabolism, sleep, and stress physiology and check body composition if desired.

Visit 02 | The Blueprint Part two of the visits is a one hour synthesis visit: Dr. Saint translates your data into a clear, individualized roadmap. You will leave with your lab overview in the context of your life, symptoms and priorities, your unique mind-body profile, and clear options for a treatment path that fits your real life.

Meet Dr. Saint, MD, MPH

Rooted in compassion and guided by science, Dr. Saint’s clinical foundation was built at UCSD, Tulane, and UCSF and solidified at Saddleback and Hoag Hospitals, where she delivered over 1,000 babies during the course of her career. This extensive background provides a profound understanding of the complexities women face at every life stage.

Her vision was further refined as the Director of Emotional Wellbeing at the Chopra Center. There, she guided high-performance executives, athletes, actors, and busy moms who appeared vibrant yet felt "running on empty" within. This taught her that vitality lives at the intersection of clinical science and nervous system resilience—not in a standard protocol.

Bridging medical expertise with integrative wisdom, Dr. Saint founded Vitality MD to look beyond labs and partner with women to build a legacy of health that lasts for decades.

A Personal Note from Dr. Saint

Medicine has always felt sacred to me.

Not because of titles or training, but because of the people. The humans behind the symptoms. The strength behind the smiles. The quiet courage it takes to keep going when your body or mind are asking for something different.

Women and moms have always been my people. I see you. How much you hold together. How often you push through. You are magnificent. You are the glue in families and the fabric of communities, schools, workplaces, friendships, and so much of humanity.

I have cared for women in hospital corridors at 3 a.m., in delivery rooms filled with urgency and hope, and later as Director of Emotional Wellbeing at the Chopra Center. There, I worked with high achieving women, many of them mothers, who looked like they were thriving on the outside yet felt depleted on the inside. They shared the exhaustion. The anxiety. The quiet feeling of not recognizing themselves anymore.

What stayed with me was never really the labs or the diagnoses. It was the invisible load women carry and how often that is minimized. It was the stories behind the symptoms. The families and organizations depending on them. The way so many women keep showing up, even when they are running on empty.

I built Vitality MD to care for you, the women, the incredible forces of nature , behind the symptoms and roles. To take you seriously. To never dismiss what you feel. To remind you that you are not failing. You are responding to a life that asks a lot; often far too much. And to encourage you to lean into your ongoing hopes and dreams for yourself and your loved ones, and NEVER lost hope.

As a physician and mother of three, dance and volleyball mom, daughter, sister, wife and loyal friend, I understand how easy it is to lose your footing while being everything for everyone. My passion is helping you come back to yourself. To feel clear again. Strong again. Steady again. To embrace hope, connection and joy. And to have fun and hopefully find meaning and fulfillment in the process working together.

Because you are extraordinary.
And you deserve care that treats you that way.
