About
Dr. Siatta Dunbar is a triple board-certified physician in Family Medicine, Sports Medicine, and Lifestyle Medicine practicing in Cedar Mill, Portland, Oregon. She earned her undergraduate degree in Architecture from the University of Virginia before building a career in construction management. Two personal losses reshaped her path. In 1997, she lost her sister to metastatic breast cancer at a young age. Years later, her mother died of sudden cardiac death at 55, the day after retiring. Those experiences drove Dr. Dunbar to leave her construction career and pursue medicine, with a focus on the science of prevention.
She pursued board certification in Lifestyle Medicine specifically to offer evidence-based interventions, nutrition, exercise, sleep, and stress management, as first-line treatment for chronic disease. She has lived this approach herself, losing 25 pounds through lifestyle strategies, gaining mental clarity, and completing her first marathon at age 50. Dr. Dunbar carries deep passion for metabolic health, cardiovascular and endothelial health, brain health, chronic disease reversal, and weight management. She uses advanced biomarker panels, including fasting insulin, ApoB, Lp(a), hsCRP, and homocysteine, to catch risk early. She serves patients with particular warmth and intentionality within BIPOC and LGBTQ communities.
