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.

Think your turmeric is doing what the label promises?

🧪 Independent testing has found that some turmeric supplements fall short of their claims, which means that you may not be getting the amount or quality you expect. Additionally, this last week a popular turmeric supplement was recalled for reports of mold contamination.

💡 And this isn’t just true for turmeric. It’s true across the supplement aisle. Quality, sourcing, and testing matter! Unfortunately, labels don’t always tell the whole story.

So what can you do?
✅ Become an informed consumer.
✅ Ask questions about sourcing, testing, and bioavailability
✅ Work with a provider who does the same.

🤝 I believe in a collaborative, partnership-based approach to care, which is why I only use supplements that meet strict quality and testing standards.

🩺 Functional medicine isn’t “alternative”.
It’s evidence-based, personalized, and designed to complement conventional care.

I sat down with Yvonne Brown of Frisco Style magazine to discuss functional medicine’s root-cause approach.

💡“Two people with the same diagnosis likely have very different paths to how they arrived there and deserve more than ‘a pill for an ill,’ whether that pill is a supplement, or a pharmaceutical."

?Should you do a detox? Do you need to?

I think starting the year with a proper metabolic detoxification is a great idea; if you understand your state of health and you are supported in that appropriately.
You could do a detox without a product, but that’s a lot of food.
To get the clinically pertinent, impactful component of any particular food - the amount that you’d have to ingest is usually greater than what you could possibly eat. 🥗🥦

Over time, toxin build-up, stress, and inactivity can be detrimental to health and longevity.
💡 This is why I recommend the Dynamic Detox program. It’s a nutritional plan designed to support your body’s natural metabolic detoxification processes (which in turn encourage alkalinity) while providing ample fuel for both cleansing and other daily activities, thereby promoting overall well-being. While many “detox” protocols are convoluted and hard to follow, this program features a step-by-step game plan for every day, including exactly what to eat, what to drink, and how to properly use Dynamic Detox and Detox Support capsules for optimal efficacy and results.

📌 The program is for anyone who wants to revitalize and rejuvenate their mind and body every few months. Even if you eat a relatively healthy diet and exercise regularly, the program is a great way to “start fresh” and get you back to feeling and functioning your best.

📌 The kit contains Dynamic Detox powder, Detox Support capsules, 1 shaker cup, plus a clear step-by-step program guide and a shopping list so you know what to eat, what to drink, and how to properly use Dynamic Detox and Detox Support capsules for optimal efficacy and results.

Have you ever had a "weird" reaction to a medication? It’s not in your head, it’s in your DNA.

Most people think detox is just clearing out toxins, but real Phase 1 detoxification happens via your Cytochrome P450 enzymes, which are encoded in your DNA. These enzymes dictate how you metabolize everything from prescription drugs to the food you eat. That’s why some medications will come with food warnings.

If you’re considering a detox, don’t just use a product your sister-in-law sells you. I get asked all the time which detox I recommend, and my go-to is Dynamic Detox by NutriDyn. It’s one of the few that’s clinically active and impactful, comes with a clear plan, and is dosed to actually work.

Full transparency: I may receive a small commission if you purchase through my wellness store. It doesn’t cost you anything extra and helps support my work. As an MD, I only recommend what I personally use with patients.

If you’re fasting, juicing, or taking mystery products without supporting your body, you could be doing more harm than good.

Yes, medication and hormone therapy can help, but they’re not the only tools. These small shifts can make a big impact on your energy, sleep, mood, and metabolism.
