What is Functional Medicine?

Functional medicine is focused on treating the individual rather than the disease. Instead of a symptoms-based approach to medicine, functional medicine takes a whole-body approach to treatment.This individualized, patient-centered approach to treatment allows patients and practitioners to work together with the ultimate goal of identifying the underlying cause of a disease.


LifeSeasons Medical Clinic (LSMC) is grounded in functional medicine, drawing from both conventional medicine and clinically proven integrative therapies. Through this holistic medicine approach, we serve patients in the Dallas-Fort Worth area and throughout the United States through telemedicine and remote consulting. You’ll notice a difference with LSMC at your first appointment and throughout your treatment journey.


At LSMC, we take extra time in the diagnostic phase, allowing us to better understand you so we can map out the best course of action using functional medicine. Our testing provides a vivid picture of your overall health and nutritional status as we examine comprehensive health risks, including genetic and epigenetic risk factors, diet, lifestyle, environments, and relationships. You’ll experience a more comprehensive intake process with us.


We often talk about root causes because that’s one of the main philosophies of our holistic-minded approach to medicine. First, we spend the time listening to and investigating your symptoms because we know they are saying something important. Symptoms point to a root cause, which is critical to treatment. As part of our functional medicine philosophy, we don’t silence your symptoms with a one-size-fits-all treatment plan. Every person is different and requires individualized treatment, which is exactly what we do using functional, integrative medicine based on sound scientific research.


In order to provide the best treatment plans possible, we conduct broad diagnostic tests, including standard blood work to more in-depth genetic, epigenetic, metabolic, and immune testing. This holistic medicine approach allows us to treat your whole body, giving us a better chance at discovering root causes. We’re committed to finding the overlooked clues that shed new light on your current situation, and our whole-body approach makes that happen!


We use functional and integrative medicine practices to collaborate with you and develop treatment plans that aim to reverse the disease instead of covering up symptoms. We also intend to work in partnership with the primary care provider (PCP) that you are already working with rather than take that provider’s place.


Following our more comprehensive, symptoms-based intake process, we identify the individual strands in your web of health and develop an effective treatment plan. Disease reversal — not symptom management — is our highest goal, and our functional medicine doctors are ready to stand by your side throughout the entire process.

Our treatment is based on your labs, your genetics, and your lifestyle right now, because we know that every person deserves a personalized treatment plan. We then give you the tools you need to make the changes that will yield the most powerful health effects. Using functional nutrition and other integrative approaches to treatment, we help patients engage in a healthier lifestyle and work to prevent and reverse disease. This lessens the burden of the disease by decreasing visits to the doctor, prescriptions, and other inconvenient aspects of traditional treatment. LSMC provides the personalized functional medicine guidance you need to experience tangible health transformation.
