Start Your Journey to Better Health with Functional Medicine
At SuMa Medicine, I take a collaborative approach to improving your health. Together, we can identify the root causes of your health problems and develop a personalized plan to address them.
If you’ve been let down by conventional medicine, know that you’re not alone. I understand that traditional approaches to chronic or acute illnesses often fall short.
My focus is on functional medicine, which means I specialize in treating the root cause of health problems like autoimmune disorders, chronic fatigue, cognitive decline, cardiovascular disease, mold toxicity, and fertility issues.
These conditions can stem from various factors, such as environmental toxins, genetics, poor diet, and lifestyle choices. Factors that conventional medicine often overlooks but that functional medicine does not.
Let’s work together to identify the underlying cause of your health issue and develop a path to better health.
Get a personalized plan tailored to you and your health and wellness goals. Feel balanced and energized again.
