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.
Dr. Marquez Loza is an adult vascular neurologist offering care for various neurologic disorders including ischemic, hemorrhagic strokes, cerebral amyloid angiopathy, subaracnoid hemorrhage, among other vascular neurology disorders.

Dr. Marquez Loza is deeply invested in researching disparities in stroke care, advancing stroke education, and improving the quality of stroke treatment. Her academic interests include addressing inequities in care, enhancing patient education, and implementing strategies for continuous improvement in stroke management.
