Alexandra Bartz

national innovation manager

Alexandra believes every person has an equal right to an affordable education. Her passion for educational equity stems from a desire to do justice to her parents’ example and sacrifice. Alexandra sees the best in others: their humanity, beauty, talents and courage. It’s her aim to help others notice, develop and unleash their gifts to impact Summer Search’s mission. Alexandra started serving others when she was a brace-faced, bi-focal wearing 14-year-old. She has been an AmeriCorps volunteer, secretary of a Board of Directors for an organization serving survivors of domestic violence, and a staff aid to a Member of Congress. For the past six years, she’s been a Big Sister to young man named David.

Alexandra graduated summa cum laude from The Ohio State University. She’s currently pursuing a Masters in Public Administration. She considers herself lucky to live in Santa Rosa, California with her husband Billy and their two-year-old Catahoula, Hooly.

Antonio Brown

National Males of Color Initiative Coordinator

Originally from Harlem, New York, Antonio draws his inspiration from his belief that social justice is a collective effort. Antonio participated in opportunity programs as a teenager himself, and he knows first-hand the role that Summer Search can play in our students’ lives. As someone who attributes much of his success to the friends, family and mentors that he’s had the privilege of learning from, he believes whole-heartedly in the ability of students to cultivate and shape the world around them.

Antonio has a BA in African and African American Studies from Dartmouth College, and has dedicated himself to deepening his understanding of the obstacles facing underserved youth, particularly students of color. You’re most likely to find Antonio at a Billiards Hall after work or wherever you hear live music.

Joining the Summer Search team in 2017, she is excited to focus her efforts domestically to impact the lives of the next generation of American leaders.

Sharon is deeply committed to Summer Search’s “pay it forward” mentality which allows for strong cross-sector partnerships with foundations, corporations, schools, summer programs, and alumni across the globe.

With a strong background in accounting and project management, she is excited to work creatively towards new business development strategies for the continuity of these effective programs.

Sharon graduated cum laude from Northeastern University in International Affairs and Languages, Literatures, and Cultures (French). She is a proud Bostonian who can’t seem to take the coordinator hat off outside of work. She enjoys planning snowboarding and rock climbing outings for her and her friends. She admits, though, that her first love is travel, and has been known to take off on a solo trip abroad to explore on her own from time to time.

This San Francisco native still calls San Francisco her home and continues to find therapy in running, baking and crafting.

Brendan Hill

marketing & Communications Manager

Brendan believes that everyone should have access to higher education, which is why he feels so honored to join the Summer Search team. He is excited to bring his creativity and passion to help promote the organization's mission, and to tell the many inspiring stories of Summer Search's students. Brendan's passion for higher education comes in part from his own college experience at the University of Miami. Go Canes! He developed an enthusiasm for summer educational programs in high school after spending four weeks away from home studying ancient Greek culture and literature. To this day, Brendan says that this summer program was one of the most enriching and inspiring experiences of his life.

Brendan also loves to explore the world. He has lived and studied in New England, South Florida, "Old" England, and now the Bay Area.

Lindsey Moriguchi

National Development manager

Lindsey is motivated by her belief that all youth should have the opportunity to know their worth and realize their full potential. 

Joining Summer Search in 2010 as a member of the Bay Area Development Team, Lindsey was initially drawn to Summer Search by how its values and mission aligned with her personal and spiritual values; however, she has stayed because of the people: the powerful and vibrant students and alumni, the committed volunteers and supporters, and the passionate and inspiring staff. The past 6+ years have cultivated a passion for Development and the ways in which it creates spaces for communities to collide and have greater empathy for one another. In 2015, Lindsey seized the opportunity to join the National Development team to make an impact on a larger scale and support students nation-wide.

Lindsey holds a bachelor’s degree in Political Economy of Industrial Societies from UC Berkeley, a National Parks Annual Pass, and a CA fishing license.

Stacey and her family live in San Francisco.

Salem Valentino

Director of Research and Evaluation

Born in rural South Carolina to “Yankees” who lived out the back-to-the-land movement, Salem watched as classmates experienced the injustices of poverty and restricted opportunities. Salem holds herself accountable to the expression, “to whom much is given, much is expected.”

After being immersed in stats coursework during her doctoral program, Salem decided to apply her skills to supporting non-profit organizations. At Summer Search, she advances the organization’s rigorous evaluative thinking, which ultimately drives practices that generate larger impacts for youth.

Salem was most recently the national director of research and evaluation for Big Brothers Big Sisters of America, and was published in the Journal of Family and Economic Issues: Profiles of Financial Stress over Time Using Subgroup Analysis. (She swears it’s a great read if you’re having a hard time falling asleep.)

Salem graduated Summa Cum Laude from UNC-Chapel Hill and completed her MS at Penn State. Most of Salem’s free time is spent wrapping up her Doctorate. Otherwise, she spends time with her husband and 3-year old in Philadelphia.

Lindsey Roark Yee
