Tricia J. O'Brien, MD

Tricia J. O'Brien, MD As a physician, I have dedicated my life's work to promoting health and wellness. Here in our offices, that’s exactly what you’ll find. Tricia J.

As a physician with over a decade of experience in holistic functional medicine, I remain deeply committed to guiding my patients with integrity, transparency, and evidence-informed care. Our functional medicine practice was founded after a long search to find a doctor that did things differently; the kind of doctor who listened, one who recognized each patient as more than a diagnosis and was willing to offer more than a prescription as treatment. Healthcare decisions are personal and should be based on a thorough discussion with a qualified medical professional who is your partner, who hears your concerns, and answers your questions with honesty and integrity. Functional Medicine differs greatly from the traditional Western Medical model as we acknowledge each patient as an individual with unique genetic predispositions, biochemical make-up, environmental exposures, lifestyle choices, social stressors, and spiritual beliefs. There simply isn’t a treatment that will work for every patient with a given set of symptoms and together we must get to the root of imbalance that is manifesting as illness or disease. Recognizing the interconnectedness of the mind, body, and spirit, treatment addresses all three. Treatment plans blend traditional Western Medicine practices with focus on prevention through nutrition, diet, and exercise plans; when indicated, Functional Medicine incorporates the latest laboratory testing to create a customized approach with prescribed combinations of pharmaceuticals and/or botanical medicines, supplements, therapeutic diets, detoxification programs, or stress-management techniques. O'Brien, MD's mission is to provide personalized, high-quality medical care. Dr O'Brien's distinctive education and training in surgery, family medicine, and functional medicine lends her the ability to manage your acute illness or work as your partner in unravelling complex, chronic illness.

Are you struggling to lose weight? Cortisol can be key. Women lose progesterone 10 YEARS before menopause, so when blood glucose is already erratic and the body is already needing to go into a fat storage state, imagine what happens if a stress response is added. Here's what you shouldn't do.

Did you know I started a YouTube channel?

We desperately need some truth-telling and discussion that isn’t marketing or biased without admitting it. Here I am shooting straight about perimenopause, weight gain, and hormone replacement.

Let's talk about perimenopause, menopause, weight loss, weight gain, and the role of stress and hormones.Apollo Neuro: https://triciaobrienmd.com/shop/apollo...

This is why having a physician who KNOWS YOU and helps you to achieve optimal health beats "longevity" treatments every day!

I want every patient to know their health risks and address them. That means tailoring their lifestyle--diet, movement, nutrition--to what will serve them the most.

It is a complex and ever more crazy world of highly biased advice coming from every reel and Insta post. Take it all with a grain of salt and partner with a physician who has the knowledge, training, experience and motivation to act as your advocate. Your life could very well depend on it.

Research Highlights: Adults with heart disease prescribed vitamin D in doses tailored to reach blood levels considered optimal for heart health (>40-80 ng/mL) had a reduced risk of heart attack by more than half (52%) compared to those who did not...

💊 Are your supplements actually working, or are they FAKE?

We’ve now seen 6 patients taking DHEA from the recommended manufacturer, but they purchased on Amazon and their lab levels didn’t budge or went down. Turns out, counterfeit and underdosed supplements are everywhere online.

🚫 Some products on Amazon have:

0% of listed ingredients 😱
Over 200% of what’s safe 🤯
Or are outright counterfeit. 😔

Your health deserves better. Learn how to protect yourself, what signs to look for, and why “Sold by Amazon” doesn’t mean it’s safe 👇

Plus, check out our online store for a curated list of clinically-backed, third-party tested supplements that we personally recommend.

In the current market where ‘experts’ are everywhere and your ticket to wellness is just one click away, it’s easier than ever to buy supplements online. But that convenience comes with a hidden risk: you may not be getting what you’re paying for, especially if you shop on Amazon. At our pra...

🚨 Are greens powders really a shortcut to better health?

Spoiler: Most aren’t replacing your fruits & veggies and some barely come close. Plus, a few contain more heavy metals than nutrition.
