Our Services
Weight Loss
Sustainable weight loss improves short- and long-term health, especially when tailored to the individual. Losing excess weight lowers risk of metabolic problems, heart disease, and chronic inflammation, and boosts energy, mood, and overall health.
I work with teens to adults using a whole-health plan: nutrient-dense food, steady blood sugar, regular movement, good sleep, and stress management. When needed, I also use treatments like GLP-1 agonists and specific peptides. This combined approach aims for real metabolic healing and lasting wellness.
Detoxification
Detoxification supports whole-body health by helping the body remove environmental toxins, metabolic waste, and inflammatory substances. When the liver, gallbladder, and kidneys work well, people often have more energy, clearer skin, better digestion, and steadier metabolism. In my practice I use targeted detox plans—liver support, gentle gallbladder and kidney cleansing—and methods to lower lingering inflammation, including after viral illness. Done safely, these steps can lower toxic load, restore balance, and improve long-term vitality.
Gut Health
Good gut health supports digestion, nutrient absorption, immunity, mood, and inflammation. Fixing the gut can improve many body systems. I use personalized plans to treat IBS, candida, parasites, food sensitivities, gluten issues, and Celiac disease. By restoring the microbiome, repairing the gut lining, and removing triggers, these plans relieve symptoms and build a stronger base for long-term health.
Cardiometabolic Health
My preventive cardiology program improves cardiometabolic health by tracking key measures—blood pressure, blood sugar, cholesterol, triglycerides, weight, and overall heart risk—to guide personalized care. Early monitoring finds problems before they become chronic. I help prevent and treat insulin resistance, prediabetes, Type 2 diabetes, PCOS, NAFLD, high blood pressure, and abnormal lipids. Using lifestyle changes, focused nutrition, and medicines when needed, patients can boost metabolism, protect their heart, and support long-term health.
Hormone Health
Balancing hormones in perimenopause and menopause greatly improves daily life and long-term health. As estrogen, progesterone, and testosterone fall, many women get poor sleep, mood swings, brain fog, weight gain, and weaker bones. Careful hormone support—through lifestyle, diet, targeted supplements, or hormone therapy—can restore balance, boosting energy, focus, mood, and metabolism. Healthy hormones also protect the heart, preserve bone, and may help maintain thinking skills, all important for living longer, healthier lives.
Nutrition & Longevity
My Nutrition & Longevity approach sees many chronic illnesses as coming from gut imbalance, poor diet, and lifestyle. Treating food as medicine, I use nutrient-rich, personalized eating plans to rebalance the body, lower inflammation, and support cells. I add targeted high-quality supplements and herbs when needed, and use medications only when clinically appropriate. Because toxins can drive inflammation and disease, I often order tests for heavy metals and environmental toxins and recommend focused detox steps to help the body heal and maintain long-term health.
