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.

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.
