Board of Directors

We share our gender pronouns because we do not want to assume another person’s gender.

Why Do Gender Pronouns Matter?

MPHA is governed by a volunteer board of directors. Each board member is dedicated to providing leadership to ensure that MPHA is the leading voice of public health issues in Maine.
