About Desert FMA

Functional medicine is a holistic approach to healthcare that focuses on identifying and addressing the root causes of health issues rather than just treating the symptoms. It aims to promote optimal well-being by considering the interconnectedness of various bodily systems and individualized patient needs. 

At Desert Functional Medicine & Aesthetics, we identify the root cause of your symptoms with a functional medicine evaluation. This evaluation will be comprehensive and may include lab testing of micronutrients, hormone levels, and gut testing. This will give a deeper understanding of any underlying imbalances that are causing disease, adverse symptoms, or lack of general wellness. The result is a treatment plan personalized for you that will provide healing at the source. Let us ensure your journey to wellness helps you find great relief and gets you back to feeling like YOU again.


We help individuals attain optimal health and wellbeing through education, professional guidance, & superior holistic and aesthetic services, so they can live a life of confidence and fulfilment.

The Six Principles of Functional Medicine

Patient-Centered Care

The focus is on the individual as a whole, considering their unique genetic makeup, lifestyle, environment, and history. Treatments are tailored to each patient’s specific needs.

Addressing Root Causes

Functional medicine seeks to uncover the underlying factors contributing to illness, such as genetic predispositions, environmental influences, lifestyle choices, and imbalances within the body’s systems.

Systems-Based Approach

It recognizes the interconnectedness of the body’s systems and views health and disease as an outcome of the interactions between these systems. Functional medicine aims to restore balance and function across all systems.

Health as Vitality

Rather than just the absence of disease, functional medicine focuses on optimizing health and vitality, emphasizing proactive approaches to prevent illness and promote overall well-being.

Personalized and Integrative Care

Treatments are tailored to each individual, integrating both conventional medicine and alternative therapies to address the person as a whole rather than focusing on a single ailment or symptom.

Emphasis on Prevention

Functional medicine places great importance on preventive measures, aiming to identify and address imbalances or risks before they lead to disease, promoting long-term health and wellness.
