Opinion: I'm a Tulsa doctor, and I must speak out for Medicaid expansion

As a father, physician and Oklahoman, I am compelled to be a voice and an advocate for Medicaid expansion. I am called to fight for the needs of families, neighbors and those on the margins of society. As a physician, I took an oath to “first, do no harm.” Without Medicaid expansion, we are quickly approaching the threshold of harm. Many have already been affected, and some harmed, by lack of access to proper health care.
