Philosophy of Care

As a vascular neurologist, my philosophy of care revolves around delivering personalized, compassionate treatment while prioritizing patient education and inclusivity. I believe that effective stroke care involves not only advanced medical intervention but also empowering patients with clear, relevant information for shared decision making. I am committed to ensuring that every patient feels respected and understood, regardless of their background. By combining cutting-edge medical expertise with a focus on open communication, I strive to provide a supportive and comprehensive approach to recovery that honors each individual’s unique needs and experiences.
