About Charlotte

A Different Kind of
Medical Practice

Charlotte Widick earned her advanced practice nursing credentials and went further — becoming a Certified Functional Medicine Practitioner through the Institute for Functional Medicine. That distinction means she doesn't just manage symptoms; she investigates the underlying systems that are out of balance.

Based in the Hill Country suburb of San Antonio, Charlotte built Root Cause Functional Medicine around a simple conviction: every patient deserves a clinician who takes the time to understand the full story — not just the chart.

The Functional Medicine Approach

We Don't Stop at
Symptom Management

Functional medicine treats the person, not the diagnosis. By examining how your body's interconnected systems communicate, we identify the root drivers of your symptoms — and build a plan that addresses them directly.

Deep Investigation

We take a thorough history — your symptoms, lifestyle, environment, and health timeline — to connect dots that standard visits often miss.

Personalized Testing

Targeted laboratory testing — hormone panels, food sensitivity screens, gut health markers, and more — guides a plan built specifically for you.

Holistic Treatment

Nutrition, lifestyle modification, supplements, and targeted therapies work together to restore balance — not just suppress symptoms.

Partnership Model

You're not a chart number. Charlotte spends the time needed to understand your goals, answer your questions, and walk the path with you.

Ongoing Support

Recovery isn't linear. We monitor your progress, adjust your plan as needed, and stay with you until meaningful change is achieved.

Insurance & Access

Transparent about costs and insurance. We work with you to make functional medicine accessible and understandable from day one.

Areas of Focus

Conditions We
Specialize In

Functional medicine is especially powerful for complex, chronic conditions that haven't responded to conventional treatment. Here are the areas where our patients see the most meaningful change.

🦋

Hormone Imbalance

Thyroid disorders, perimenopause, menopause, adrenal fatigue, and sex hormone dysregulation — restored through targeted testing and natural support.

🫀

Autoimmune Support

Hashimoto's, rheumatoid arthritis, lupus, and other autoimmune conditions addressed at the root — immune modulation, gut healing, and inflammation control.

🧬

Gut Health & Digestion

IBS, SIBO, leaky gut, food sensitivities, and chronic bloating — healed through personalized nutrition and gut-restoring protocols.

⚡

Chronic Fatigue

Persistent exhaustion that sleep doesn't fix often has a root cause — mitochondrial dysfunction, nutrient deficiency, or hidden infection — and it can be addressed.

🧠

Mental Wellness

Anxiety, brain fog, mood disorders, and sleep disturbances often trace back to nutritional gaps, hormonal shifts, or gut-brain axis dysfunction.

⚖️

Metabolic Health

Insulin resistance, weight management, prediabetes, and metabolic syndrome — reversed through lifestyle medicine and metabolic restoration.

Patient Stories

Real Patients.
Real Results.

"I had been to six specialists for my autoimmune condition before finding Charlotte. She actually listened for 90 minutes on my first visit and asked questions no one else had thought to ask. For the first time, I feel like someone is treating the cause, not just the label on my chart."

S.M.
San Antonio Patient
Hashimoto's Patient

"After years of feeling exhausted no matter how much I slept, Charlotte ran the right tests and found three underlying issues that explained everything. Six months later, I have my energy back and I'm finally sleeping through the night. This practice is a game-changer."

R.T.
San Antonio Patient
Chronic Fatigue Patient

"Charlotte made me feel like a partner in my own care, not a number on a clipboard. She took the time to explain every test result and every recommendation. My hormones are balanced for the first time in a decade, and I feel like my 30-year-old self again."
