Your “Big Picture” Endocrinologist:As a physician with specialized training and experience in endocrinology, diabetes, and metabolism, I recognize the human body’s complex nature, where organs and their functions are deeply intertwined. To broaden my understanding and address patents’ diverse health aspects, I pursued additional board certifications in lipidology, hypertension, and obesity medicine. These certifications are closely linked to endocrinology and play pivotal roles in overall health.Through this expanded knowledge base, I have developed a unique skill set in the realm of integrative endocrinology. This cross-disciplinary expertise empowers me to not only attend to my patients’ specific hormonal needs but also to take a holistic approach to their overall well-being. By addressing the interconnected relationships among various bodily organs, I aim to provide more effective and personalized care that transcends isolated medical symptoms. In short, this approach allows me to consider the broader context of my patients’ health, resulting in a more thorough and integrated endocrine care experience.Beyond Symptoms:When you choose me as your doctor, I move beyond simply assessing and treating isolated symptoms. Instead, I focus on uncovering the underlying or “hidden” factors contributing to your condition. I do this by considering the dynamic interplay between various hormones, metabolic processes, and bodily organs, all of which influence your well-being. Dr. Tashko is rated as an Advanced provider by MediFind in the treatment of Vitamin B12 Deficiency. His top areas of expertise are Abdominal Obesity Metabolic Syndrome, Type B Insulin Resistance Syndrome, Mitochondrial Complex V Deficiency, and Cytochrome C Oxidase Deficiency.
