Heather C. Mefford, MD, PhD

Genetics

On staff since August 2008

Children's Title: Attending Physician

Academic Title: Assistant Professor

Research Center: Center for Integrative Brain Research

"Geneticists are driven to understand the genetic basis of disease because we believe this information will lead us to better treatments and cures. I am so fortunate to be able to interact with a great group of researchers in Seattle who are using technology to understand disease. The scientists and the physicians I work with are very innovative and collaborative, which creates an inspiring, fun and successful working environment."
