Yvonne Berumen

Vice President and Dean for Admission & Financial Aid
(She/Her, Habla Español, First-Gen)

Yvonne grew up in Pico Rivera, California where she attended El Rancho High School. A Pitzer alumna from the Class of 1997, Yvonne received her Bachelor’s degree in Psychology and Sociology. In 2005, she earned her Master’s in Higher Education with an emphasis in Quantitative Analysis. Yvonne has over 19 years of experience in higher education and college counseling. Prior to returning to Pitzer, she was the Vice President of Scholarships and Academic Support for the Hispanic Scholarship Fund where she managed HSF’s strategic outreach to students, parents and educational constituents, which included developing content that promoted college attainment and academic success.

In her spare time, Yvonne enjoys staying active through dance and hikes with her dogs.

Recruitment territories: California, Hawaii, International (Europe, India, Pakistan)

Favorite Place in the Claremont Village: The Circus Studio is my favorite spot. It’s owned by a Pitzer alumnus and they offer aerial circus classes along with yoga and Pilates. Students have been able to take classes for PE credit there, too!

Fun Fact: I have been a dancer since I was 4. I was so small when I started that my mom couldn’t find ballet shoes that fit me. I love all forms of dancing and it’s my creative outlet.

My College Search Advice: As a former college counselor, I could share pages of advice, however, the first piece of advice I always give students is to reflect and ask themselves what makes them happy. What learning environment is best suited to them? Don’t be led by the rankings or where your friends are applying. Start with you. Do you learn best in a small or large environment? Do you want a residential campus? What type of students do you want to be surrounded by? What are you passionate about? Chances are, the colleges will have the major you’re looking for and basic amenities, but being in the right school can impact your overall satisfaction and whether or not you graduate from a particular college.

David was born and raised just south of Boston in Norwood, Massachusetts. He attended Stonehill College in Easton, Massachusetts receiving his BA in Graphic Design. During his time at Stonehill he was heavily involved in student leadership through the admissions office and the orientation team, and started his love for travel during a semester abroad in Florence, Italy. After his transformative experience in college, he continued his passions for student leadership and development in the college admissions field since 2013. He received his MEd in Higher Education Administration in 2018 at Northeastern University.

Outside of work, he enjoys running, hiking, and all things pop-culture related.

Fun Fact: It’s a personal goal to have visited at least as many states as my age, luckily I’m a little ahead right now having visited 32 states so far!

My College Search Advice: Focus on the college community you feel you’d thrive in most. It is important to look at what are the various factors that are on your must-have checklists, from academics, to extracurriculars, potential study abroad opportunities, and the campus community. What are your must-haves and what can you have flexibility on to still be challenged to grow? The fit of an institution will help you go far.


Hayley Burke

Assistant Director of Admission
(She/Her, First-Gen)

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. Hayley loves to travel, and spends much of her time subtly sending plane ticket deals from Scott’s Cheap Flights to her friends. Her dream destinations include Greece, Montana, Spain, Chile and Mexico City. 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 remains committed to this mission in her role as an Admission Counselor, working to make Pitzer accessible for formerly incarcerated individuals. Outside of work, Hayley is an avid beach-goer and fearlessly experimental baker who loves nothing more than to lean into her extroversion and spend all of her time with friends and family and food.

Recruitment territories: Alabama, Arkansas, California, Mississippi, New Mexico, Texas, International (Middle East and Asia, excluding India, Pakistan, China, Hong Kong, Taiwan)

Favorite Place in the Claremont Village: Crème Bakery! If you love baked goods, Crème is THE place to get your fix. Everything is made with real butter, and lots of it. I recommend the lemon scone or any of the croissants.

Fun Fact: I was in NJROTC for all four years of high school. (Embarrassing pictures of me in uniform available upon request.)

My College Search Advice: When building your college list, make a spreadsheet with each college and its relevant information. Does the school require standardized tests? List it there. Want to get in touch with your regional counselor? Write down their email. Staying organized will help ensure that you meet your deadlines and feel confident throughout the process.


Erin Griffin

Assistant Director of Admission
(She/Her, Habla Español)

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 heading to the ocean, hiking, and enjoying all things food.

Recruitment territories: California, Georgia, Iowa, Indiana, Kansas, Maine, Massachusetts, Michigan, Missouri, New Hampshire, Rhode Island, Vermont, International (Oceania)

Favorite Place in the Claremont Village: 42nd Street Bagel – their everything will leave you wondering how it is physically possible for that many poppy seeds to fit on one bagel. Also Saca’s Mediterranean – because it is just so good.

Fun Fact: I’ve driven across the country three times.

My College Search Advice: Focus on finding the college that ‘fits’ you the best. Ask if there is good student-faculty interaction, but also ask what those interactions are like. Ask if there are study abroad opportunities, but also ask how many, how accessible they are, and what sets them apart from other school’s offerings. Consider the various factors you need for academic and extracurricular success, and seek out those specifics as you get to know a school. Though there are 100 colleges out there that are the perfect fit for you, this level of discernment can help narrow it down.

Favorite Place in the Claremont Village: Some Crust Bakery has the best treats in town! Their cupcakes are not only beautiful to look at but delectible to taste. It’s dangerous working so close to something that delicious.

Fun Fact: While most people were born in their local hospital, I was born in the living room of my childhood home (intentionally)!

My College Search Advice: There are SO MANY colleges you could be happy at–many of which you’ve probably never heard of. Look high and low for schools, and keep an open mind and heart. College is a wonderful and enriching experience, and that’s true regardless of a school’s name recognition.

My College Search Advice: A lot of people don’t know what they want to study in college, and that’s okay!

Also, don’t be afraid to ask the admission office questions, we’re here to help in any way possible!

My College Search Advice: When you begin your college visits, it’s easy for the colleges to blend together and become confusing. I recommend that students record a short video of themselves noting their first impressions so you can always refer back to how you first felt about a college.

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.

Favorite Place in the Claremont Village: Claremont Village Eatery – super cute with great food and coffee!

After retiring, the lure of sunny Southern California, the beach, and a diverse population resulted in a move.

Her two grandchildren hold top-billing in her life and she looks forward to being with them whenever possible.
