As a museum educator, Ehrlich's work has driven innovation in the field of teen programs. Teen programs Ehrlich developed continue to be used as models and applied in museums locally and internationally. Ehrlich has a proven track record of increasing audience engagement through the promotion of  shared leadership, community-based practices, and inclusion and diversity. Lessons and programs she develops are visiter-centered and include inquiry-based activities that are dialogical and multimodal.  

In her role as Manager of School, Youth, and Family Programs at the Museum of Arts and Design (MAD), a craft-based art and design museum in New York City, Ehrlich managed and trained Artist Educators who provided individualized art and craft-based learning experiences for school, teacher, youth and family audiences. During her time at MAD, family programs yearly attendance increased 1150%, attracting greater attendance rates than the museum recorded annually for five years prior.  Programs Ehrlich curated included Knitting Nation 15, a site-specific and live labor performance by artist Liz Collins, hands-on art-making workshops in partnership with the Robert Blackburn Printmaking Workshop, and MAD's first summer family film festival in partnership with the New York International Children's Film Festival. Additionally, Ehrlich managed and taught in the Arts Reach partnership, a customized museum-school partnership for middle and high school students suspended from public school. She also led salon-style professional development for educators, including Teaching Art Through Team-Building Activities and Teaching Art Using Dialogue.

While at the Brooklyn Museum, in her role as Senior Museum Educator and Teen Programs Coordinator, Ehrlich increased yearly attendance rates for teen programs by 1750% and grew out-of-school programs for teens from one program a year to five. Her novel approach paved the way for expanding conceptions about contemporary teen programs in art museums. In addition to facilitating Brooklyn Museum's flagship teen program, Museum Apprentice Program (MAP), Ehrlich conceptualized and developed several unprecedented teen programs responding to teens' interests in art and art history, event planning, technology, feminism and LGBTQ+ topics.  Ehrlich co-founded the Cultural Institutions Teen Programs group (formerly NYC Art Museum Teen Programs group) in 2008.

Ehrlich's expertise in art and museum education include: teaching methodologies, community and visitor engagement, event production, best practices and standards in gallery-based teaching, curriculum writing and development, diversity training, strategic planning, goal setting and evaluation, visitor experience and audience development, increasing and expanding audience retention and participation, risk management, exhibition and interpretative materials design, new technologies and archiving. ​
