    • Send regular communications to OSPA members about the activities of the OSPA to keep members informed, engaged, and renewing their OSPA membership every year.
    • Contact PA employers to promote the OSPA and ask them to offer their PA employees membership in the OSPA as a benefit of employment.
    • Ask PAs to volunteer as OSPA officers, committee members, and other essential roles.
    • And ultimately, by growing OSPA membership, to build a strong OSPA that is more effective politically and strengthening the PA profession in Oregon.
