Erin Callison

Program Director

Erin is deeply passionate about helping young people transform what they believe is possible for themselves. Erin’s journey to Summer Search began as an Outward Bound Instructor for an expedition of all Summer Searchers inspired her with their self-reflection, resilience, and willingness to step out of their comfort zone.

Erin, a first-generation college student, received her B.A from Clark University and a Masters of Arts in Teaching program at Clark University. During her fieldwork in South Africa and rural Haiti, Erin experienced the transformative power of being outside of her comfort zone. Erin has taught 8th grade World history and was an Lead Wilderness Instructor at Outward Bound.

In her free time, Erin finds herself scheming new outdoor adventures, mountain biking, and throwing homemade pizza parties.

Alex Cromer

Program Associate

Alex is passionate about seeing those around her truly believe in their worth and abilities. She is driven by the narrative of empowerment and seeing underserved populations have abundant resources. Alex is attracted to the framework in which Summer Search serves students because of the thoughtful, holistic approach, and the high emphasis on equity.

Alex holds a B.A. in psychology, with a minor in sociology, from Eastern University. While in college she was deeply changed by mentoring high school girls in navigating spirituality and was also shaped by her time abroad in Uganda. Quickly, Alex was culturally immersed and taught to think beyond her own socialization and community. Pairing time abroad with interning for Outward Bound, she began to see the value of good questions, living in the tension, and seeking real adventure. Alex worked in Philadelphia as a social worker, serving single mothers, before landing at Summer Search.

Seeking the fullest life possible, Alex can be found outside. Whether its bungee jumping, caving, or a road trip to a National Park, Alex is someone who pursues the wild things in life.


Kaitlin Irvine

College Access & Success Manager

Kaitlin has a deep belief in providing access to opportunities for all. At Summer Search, she loves connecting with students and empowering them to find the best opportunities for their big third trip -- college!

Kaitlin holds a B.A. from Dickinson College and a Masters in Education from the College of William & Mary. During college, she studied in Cameroon, Africa, where she became a true member of her host family, spoke French, and ate her weight in fresh mangoes. Kaitlin worked for an Upward Bound program during college summers.

Kaitlin has been a college adviser in a rural public high school and is a recent transplant to Philly.

She can be found at the dog park, reading books, discovering hidden culinary gems, or scheming about where her passport will take her next.

Sherella Williams

Senior Development Associate

Sherella is excited to share her passion for development that is deeply intertwined with her passion for her vibrant home city of Philadelphia. Sherella’s goal is to ensure that the wonderful opportunities that Philadelphia has to offer are accessible to all communities across the city.  

Sherella holds a B.A. from Byrn Mawr College, and has studied at Berlin’s Humboldt University, an experience that sealed her commitment to the German language (including its dialects!) and inspired her to teach in two Austrian high schools after college through Fulbright and the Austrian-American Educational Commission. Aside from her time overseas, Sherella previously worked at Public Health Management Corporation on the Out-of-School Time Project, where she supported quality after-school programing in over a hundred sites across Philadelphia.

Sherella can often be found redefining her limits in Muay Thai class, thinking of interesting new ways to maintain her German fluency, or searching for the best pancake spot in West Philly.
