In late 2001, Melissa and her family immigrated to the United States (US).
Upon graduating from high school, Melissa continued her educational goals as a non-traditional student at the Harvard Extension School (HES), a school within the Harvard University umbrella. HES refreshed the love of learning that Escuela Americana had planted in her from an early age. At HES, she completed a Bachelor of Liberal Arts (ALB) in Psychology and a minor in Communications as well as a Graduate Certificate in Business Communications. Soon after graduating, she began working in the mental health field as an Outreach Worker. She worked with adults and provided intensive case management services to support clients with acute mental health challenges in order to increase their stability and access to resources within their communities.
In order to further her education and professional goals, Melissa began her journey towards a Master of Social Work (MSW) at Boston College (BC). At BC, Melissa was part of the Latinx Leadership Initiative (LLI). The LLI is a cohort specifically geared towards social workers who want to work with Latinx (Latine) communities. As part of her degree requirements, she completed two internships; one at North Suffolk Community Services’s Children’s After School Program (CASP), and the second within the Social Work Department of Dana-Farber Cancer Institute (DFCI).

She uses her knowledge of the client to create detailed reports, connects clients with programs and services to set them up for success, and uses a combination of trauma based practices and therapeutic support when meeting with clients. She uses her language skills and cultural sensitivity to guide the work that she does at the firm to properly advocate for clients and their needs.
