Karen Shimada, MPH, Executive Director

Karen Shimada recently joined OrOHC as the new Executive Director.

Karen brings over 30 years of public health, gerontology, nonprofit and primary care clinic management experience to OrOHC. Her passion for equity and social justice for all, especially those marginalized, isolated or without access to health care, is reflected in her career of service in the nonprofit sector.  

Karen just completed five years as the Executive Director of Clackamas Volunteers in Medicine, the only free clinic in Clackamas County providing primary care to uninsured and underinsured residents.  Each day she saw evidence that oral health stood out as one of the most significant gaps in the continuum of services patients’ need.

“I am very excited to embrace the challenge of building on our strong foundation and growing OrOHC into the future,” states Shimada.   “I am committed to ensuring every voice is heard as we develop our membership model and expand pathways for integrating oral health and primary care.”
