Hayley Burke

Assistant Director of Admission

Hayley is lucky to have spent her entire life in sunny Southern California. That is, aside from the five years she spent freezing in Philadelphia, PA at Bryn Mawr College. After graduating in 2015 as a sociology major, she stayed on to pursue her Master of Social Work degree from Bryn Mawr’s Graduate School of Social Work and Social Research. During college, Hayley had the opportunity to leave the country for the first time. Bitten by the travel bug, the list of destinations she’s visited now include: Singapore, Cambodia, Copenhagen and Guantanamo Bay, Cuba! While at Bryn Mawr, Hayley was surrounded by extraordinary women who pushed her to become a strong advocate against social inequity and injustice. Working towards this goal, she co-founded a reading and writing group for local incarcerated women. She also helped launch a new group for first-generation students, faculty and staff on campus called First-Goers. Now that she’s out of college, Hayley has discovered this new “free time” thing, which she likes to spend doing Pilates, completing her goal of seeing every National Park, and baking cookies for her side gig, Baking Bad!

Recruitment territories: Alabama, Arkansas, California (Orange County, South, South Central, South Bay of Los Angeles), Kentucky, Mississippi, New Mexico, North Carolina, Pennsylvania, South Carolina, Texas, International (Asia, excluding India, and the Middle East)

Erin Griffin

Assistant Director of Admission

Erin was born and raised in Carpinteria, California where she attended Cate School. Wanting to explore and challenge herself after graduation, she set out east to Colby College in Waterville, Maine where she earned her degree in Spanish and Environmental Studies. She devoted her time at Colby to the Residential Life program as a Community Advisor and Area Resident Director, volunteering at the local homeless shelter and teen center, and working as a Senior Fellow in the admission office. During her four years she spent a semester abroad in Córdoba, Spain and took weekends to explore Maine’s small towns, mountains, and extensive coastline. Although a fan of the snow, Erin made her way back west after graduation and spent some time interning at a disaster relief organization in her hometown. Eager to jump back into higher education and admissions work, she found Pitzer. In her free time Erin loves the ocean, hiking, and all things food.

David Dysart

Associate Director of Enrollment Systems

Born and raised in Southern California, on the computer is where he spent most of his days.  David has made his rounds working in Higher Ed as well as the Public and Private sectors, but he is thrilled to be back in a university setting here at Pitzer.  With an educational background in Industrial/Organizational Psychology, he has always tended toward the analytical side of life, but he merges this with a love of the arts.  A board member of a community theatre, he enjoys still being involved even if it’s not on the stage as often.

Lina Sandve

Admission Assistant

Lina grew up in Arizona, but spent many years in Albuquerque, NM where she worked at the University of New Mexico as a Department Administrator. While there she took advantage of the Tuition Remission program, taking 1 or 2 classes a semester, and after 12 determined years, earned her Bachelors in Business Administration degree. After retiring, the lure of sunny Southern California, the beach, and a diverse population resulted in a move. Her daughter is a Scripps alum who works at Harvey Mudd, and her son-in-law works at Pitzer as well – this is a Claremont Colleges family! Lina enjoys the beach, reading, dancing, watching the Packers play football, and meeting people. Her two grandchildren hold top-billing in her life and she looks forward to being with them whenever possible.
