Rosa leads the credit union's initiatives and efforts to expand access to financial products and services in the Upper Manhattan of New York. Thanks to her background in microfinance NTFCU was able to launch in-house mortgage and small business lending, which were outsourced before. The extent of the work includes ITIN holders who have equal access to financial products and services. During her years of work, Rosa played an active role in the implementation of collaborative work with Hispanic Consulates and the Juntos Avanzamos network, where she is a member of the Selection Committee. Her involvement in the Board of community-based organizations and small CDFIs, as well as advocacy groups, allows her to gain a broader knowledge of the financial needs of different groups and tailor the credit union's offer. Before moving to the USA, Rosa led projects and programs in the microfinance sector of urban and rural areas of Peru.
