Over the next several months, we plan to support many more candidates with robust, personalized support. And in September, we plan to host our largest Summit yet in Philadelphia.

That’s why we’re fired up to welcome three new staff members: Santiago Martinez, Julia Leitner, and Christopher Marte.

Santiago, Julia, and Chris each join our team so we can scale our work to serve more candidates and build stronger supports for our community.

We can’t wait to share what we have in store. In the meantime, here’s a bit more about each of them.
