His PhD work focused on behavioral economics and outcome measurement issues related to substance use in adolescents and young adults. After spending a year learning advanced quality improvement and performance measurement techniques, he’s excited to join the faculty at Hennepin Healthcare to combine these efforts to improve the care for people who live in the Twin Cities community.

Dr. Helen Wood

Dr. Wood has broad experience in both primary care and psychiatry. She has completed residencies and board certification in both internal medicine and psychiatry. She has extensive experience in addiction and community psychiatry. She joined the Primary Care Behavioral Health team at Hennepin Healthcare in 2016 and divides her time between doing psychiatric consultations in our primary care clinics and her private practice. Providing evidence-based treatments for substance use disorders is a rewarding part of longitudinal psychiatric care. MAT (medication-assisted treatment) is one of our great breakthroughs in addiction medicine and I am delighted to help the ECHO team with a psychiatric perspective to this treatment.
