Find—and fix—the “why” behind your symptoms through functional medicine with advanced testing and a plan that fits your biology.
Functional medicine is a patient-centered, systems-based approach that looks for why symptoms happen—then treats the root causes with personalized plans (lifestyle, nutrition, targeted therapies) rather than quick fixes. It complements conventional care and emphasizes prevention, participation, and whole-person health.
Your gut is home to up to 80% of your immune system, and imbalances here (dysbiosis, “leaky gut”) can trigger chronic inflammation, food sensitivities, and autoimmune flares. By healing your gut lining and optimizing microbial balance, we help your immune system switch from misfiring to protective—so you feel stronger, clearer, and less reactive.
Hormones are your body’s chemical messengers — coordinating energy, mood, reproduction, sleep, and metabolism.
When hormones fall out of balance (due to stress, nutrition, toxins, or signaling faults), symptoms like fatigue, weight shifts, mood swings, sexual dysfunction or sleep disruption often follow. We look upstream to reset hormonal pathways — not just “replace” — using root-cause strategies so your system can self-regulate again.
Metabolism is your body’s engine for turning food, hormones, and oxygen into usable energy. When that engine bogs down (from insulin resistance, thyroid issues, mitochondrial dysfunction), you might see stubborn weight gain, fatigue, or sluggish recovery.
We dig into upstream drivers to restore metabolic balance—so your body runs clean, efficient, and strong.
Your brain and stress systems (HPA axis, autonomic balance) regulate focus, mood, resilience, and recovery. When stress is chronic or your nervous system is overtaxed, you may experience brain fog, anxiety, sleep disruption, or mood swings. We support your stress biology—resetting regulation, toning resilience, and returning your brain/body to balance.
Your environment (toxins, nutrition, lifestyle, exposures) constantly communicates with your cells and organs. Even low-level toxin burden or poor nutrient quality can slowly erode function, trigger inflammation, and disrupt detox systems. We assess, reduce, and remediate these inputs to turn your environment from a burden into a foundation for healing.
Visit 1 • Deep Assessment
60–75 min history, symptom map by organ system, medication/supplement review, and targeted exam. Order labs as needed.
Visit 2 • Findings & Plan
Review labs (functional ranges explained), prioritize root causes, and build your plan across nutrition, sleep, stress, movement, and appropriate therapies.
Visit 3+ • Momentum & Results
We build on your progress by fine-tuning your plan, addressing new challenges, and adjusting therapies as your labs and health markers improve. Each follow-up keeps you moving forward—ensuring sustainable results, resilience, and long-term vitality.

Conventional medicine excels at acute care and necessary procedures. Functional medicine complements it by asking: “Why did this start—and what keeps fueling it?” We blend standard diagnostics with deeper lifestyle and systems-biology testing, then intervene with lifestyle, nutrition, and targeted therapies before—or alongside—medications when appropriate.

Yes—our approach follows systems biology and lifestyle medicine, aligning with organizations like the Institute for Functional Medicine and is used by major centers such as Cleveland Clinic. We integrate standard care and current evidence with nutrition, sleep, stress, and targeted therapies.
We’re a cash-based clinic so we can spend more time and tailor care. We provide HSA/FSA receipts.
Many notice changes in 2–6 weeks as drivers are addressed; deeper issues may take longer. We set realistic milestones and adjust your plan.
We offer plans with varying features, support, and customization options to fit your needs.
We commonly help people with gut and immune issues, hormone imbalances, fatigue, metabolic challenges, chronic infections, inflammation, and autoimmune conditions. Our focus is always on root causes, not just symptoms.
We work alongside your current care and prescriptions. Our goal is to support your health with nutrition, lifestyle, and targeted therapies that complement—not replace—your primary care.
After the first two visits, most people check in every 2–3 months to track progress, adjust labs, and fine-tune plans/protocols. Frequency depends on your goals and how quickly your body responds.
Yes. Many people come to us with fatigue, brain fog, gut issues, or hormonal symptoms even when standard tests are “normal.” We look deeper at underlying systems to uncover hidden drivers.
Yes, we provide telehealth visits for all US residents. This makes it easy to stay on track with your plan no matter your schedule or location.
We begin with essential baseline labs such as hormones, lipid panel, CBC, CMP, and thyroid panel. More specialized or advanced testing is only recommended if there are specific concerns or if your progress suggests it would add meaningful insight. This way, we keep your care both comprehensive and cost-effective.
Your health journey doesn’t have to be confusing or overwhelming. At Healing Advanced Solutions, we uncover root causes and create a plan tailored to you. Start today with a comprehensive functional assessment and take control of your well-being.
