Meet the Newest Members of the GEO Team

  • By Grantmakers for Effective Organizations, March 23, 2022

For the last couple of years, Covid-19 has made social separation a necessity for public health. But distance should not curb progress – as grantmakers continue to make shifts in philanthropic culture and practice, we too have seen our own changes here in the GEO team. With our first in-person conference since the start of the pandemic coming up, we wanted to take a moment to introduce the GEO community to our newest staff members.
