If you've been to your primary care doctor and left with a prescription but still no answers — you're not alone. Many patients in Roswell, GA and the surrounding areas of Alpharetta, Marietta, Johns Creek, Sandy Springs, Cumming, and East Cobb are asking a deeper question: Is there a better way to get to the root of what's wrong with me?
That question is exactly why functional medicine is growing — and why Dr. Sonza Curtis, PA-C and Doctor of Naturopathy at Three D Wellness, has dedicated her practice to a model that goes far beyond symptom management. This post breaks down the key differences between functional medicine and conventional medicine so you can make an informed decision about your healthcare.
Conventional medicine — also called allopathic or Western medicine — is the standard model practiced at most doctor's offices, urgent care centers, and hospitals. It is excellent at treating acute conditions: infections, broken bones, emergency situations, and surgical needs.
However, conventional medicine typically works by identifying symptoms and matching them to a diagnosis, then treating that diagnosis — often with medication. Lab work is ordered based on standard reference ranges, and if your results fall within those ranges, you're told you're "normal," even if you don't feel normal at all.
This is one of the most frustrating experiences patients describe: being told everything looks fine on paper while continuing to feel exhausted, foggy, anxious, or unwell.
Functional medicine is a systems-based, root-cause approach to health. Rather than asking "What disease do you have?" it asks "Why are you not functioning optimally — and what do we need to do to fix that?"
At Three D Wellness in Roswell, GA, Dr. Sonza Curtis practices functional medicine with a philosophy built on one core belief: testing, not guessing. She believes you when you say you don't feel well — even when your conventional labs look normal. Her approach is to dig deeper, run advanced testing, and find the actual underlying cause of your symptoms.
Functional medicine treats the whole person — body, mind, and lifestyle — and recognizes that systems in the body are deeply interconnected. A thyroid problem may be rooted in gut dysfunction. A hormonal imbalance may be triggering an autoimmune response. Nothing happens in isolation.
Conventional medicine identifies a symptom and treats it. Fatigue? Here's an antidepressant. High cholesterol? Here's a statin. Acid reflux? Here's a proton pump inhibitor. These treatments may relieve the symptom but don't address why it happened.
Functional medicine asks why the symptom exists in the first place. Fatigue might trace back to an underconverted thyroid hormone, poor gut absorption, mitochondrial dysfunction, or chronic inflammation. At Three D Wellness, Dr. Curtis doesn't stop at the surface.
Conventional medicine typically orders a basic thyroid panel — usually just TSH. If your TSH is within range, you're told your thyroid is fine. But many patients with thyroid dysfunction have a TSH that appears normal while other critical markers are out of range.
Functional medicine at Three D Wellness runs up to 8 thyroid markers, including Free T3, Free T4, Reverse T3, Total T3, Total T4, TPO antibodies, thyroglobulin antibodies, and TSH. This comprehensive panel reveals patterns that standard testing misses — and that's exactly where the real answers live.
The same principle applies to hormones, gut health, inflammatory markers, nutrient levels, and more. Advanced testing is not optional — it's how Dr. Curtis finds the truth your body is trying to tell her.
Conventional medicine typically only evaluates the gut when you have obvious digestive symptoms — bloating, constipation, or diarrhea.
Functional medicine recognizes that the gut affects everything. At Three D Wellness, Dr. Sonza Curtis checks and treats the gut on every single patient — because many people don't realize they have gut absorption problems that are silently undermining their health. Poor gut absorption means that even the best supplements or nutrition plans won't work the way they should. Healing the gut is foundational to healing the rest of the body.
Conventional medicine appointments are typically 10–15 minutes. Physicians are often managing large patient panels and must work efficiently within system constraints.
Functional medicine at Three D Wellness takes a very different approach. Your initial appointment can be up to 90 minutes. Dr. Curtis takes the time to hear your full story — your history, your symptoms, your lifestyle, your stress, your gut health, and what you've already tried. That time is what makes accurate, personalized care possible.
Conventional medicine is often protocol-driven. There's a standard of care pathway for most diagnoses, and deviations from it are uncommon.
Functional medicine is patient-driven. Dr. Curtis wants to hear your pain points — what's frustrating you, what's limiting your life, what you've been told is "normal" that doesn't feel normal at all. Her practice is built on the belief that your symptoms are real, your experience matters, and you deserve real answers.
Many patients at Three D Wellness have been dismissed by conventional providers before finding Dr. Curtis. They were told their labs were fine. They were offered antidepressants when they weren't depressed — just exhausted. They were given diagnoses that didn't fit. And then they found a provider who actually listened — and found the root cause.
Conventional medicine relies heavily on pharmaceutical interventions. There is absolutely a place for medications — but they are often the first and only tool used.
Functional medicine uses a full toolkit: targeted nutrition, evidence-based supplementation, lifestyle modification, stress management, hormone optimization, gut repair protocols, and — when necessary — medication. The plan is customized to your biology, not applied from a template.

Dr. Sonza Curtis holds a 4.9-star Google rating because her patients consistently report feeling heard — and getting results. She serves patients from Roswell, Alpharetta, East Cobb, Marietta, Johns Creek, Cumming, Sandy Springs, and throughout the greater Atlanta area.
It's important to say clearly: conventional medicine is not the enemy. It is essential for acute care, emergency medicine, infectious disease, surgery, and many other critical applications. Many patients benefit from a combination of both approaches — conventional medicine for acute issues and functional medicine for chronic, complex, or unexplained conditions.
Dr. Curtis welcomes patients who are currently working with other providers. She believes in collaborative care and will always prioritize your safety and wellbeing above any ideological commitment to one model.

This is one of the most common questions patients ask. Three D Wellness operates on a cash-pay model, which means the practice is not in-network with insurance providers. This structure is intentional — it allows Dr. Curtis to spend the time your care actually requires, run the testing that tells the whole story, and create a plan without the limitations that insurance-driven care imposes.
Many patients find that the investment pays for itself in reduced prescriptions, fewer ineffective treatments, and a clearer path to real health. HSA and FSA funds can often be used. Contact the office directly for current pricing and program options.
Yes. Many patients at Three D Wellness maintain their relationship with their primary care provider while working with Dr. Curtis for functional medicine support. The two approaches complement each other well.
Three D Wellness specializes in thyroid disorders (including Hashimoto's), hormonal imbalances, perimenopause and menopause, autoimmune conditions, gut disorders, chronic fatigue, and unexplained symptoms that haven't responded to conventional treatment.
Dr. Sonza Curtis believes you when you say you don't feel well — even when conventional labs show normal results. She runs advanced testing that goes beyond standard panels to find what's actually going on. Normal labs don't always mean optimal health.
Functional medicine uses medications when appropriate, but they are not always the first or only tool. Dr. Curtis creates personalized plans that may include nutrition, supplements, lifestyle changes, hormone optimization, gut repair, and medications when clinically indicated.
Both approaches are root-cause focused, but they differ in training and tools. Dr. Sonza Curtis holds credentials as both a PA-C (Physician Associate — Certified) and a Doctor of Naturopathy, which means she brings the clinical precision of conventional training alongside the holistic, systems-based philosophy of naturopathy. This dual background gives her patients access to the best of both worlds.
