Philosophy of Care
“I view health as a dynamic and holistic state shaped by physical, emotional, social and environmental factors. So, I believe the foundation of effective health care lies in prevention practices. ractice preventive–care approach that emphasizes lifestyle modifications, early intervention, patient education, and preventing progression of chronic diseases. Many chronic conditions can be prevented or improved through intentional changes in nutrition, physical activity, stress management and healthy habits.”
