Through Kaya Girl Legacy, Dr. Yojana Rodriguez-Humbert is reshaping how Caribbean and diaspora families approach genetic health—moving from crisis response to proactive, informed care.

 

A Purpose Rooted in Heritage, Motherhood, and Mission

For Dr. Yojana Rodriguez-Humbert, a proud Cuban woman and founder of Kaya Girl Legacy, Inc., purpose is not something she discovered—it is something she lived, endured, and ultimately transformed into impact.

Based in Miami Shores, Florida, her work extends far beyond geography. It speaks directly to underrepresented communities, including Caribbean families, where conversations around genetic health are often delayed, overlooked, or misunderstood. Kaya Girl Legacy operates at the intersection of genetic health advocacy and public health, advancing early screening, education, and equitable access. What distinguishes the organization is its foundation in lived experience—bridging families, healthcare systems, and policy to ensure that no one has to navigate genetic health challenges alone.

 

Kaya’s Story: The Heart of the Legacy

At the center of this work is a story that is both deeply personal and profoundly impactful.

Kaya Jana Humbert was, in her mother’s words, “a baby in bloom”—radiant, joyful, and full of purpose. Her name, meaning “restful place” and “God is gracious,” reflected the peace and presence she carried, even in the face of unimaginable challenges. At just two weeks old, Kaya was diagnosed with Sphingosine Phosphate Lyase Insufficiency Syndrome (SPLIS), a rare genetic condition so newly discovered that fewer than 50 cases had been documented worldwide at the time.

 

Despite having two healthy children and prior genetic testing, Dr. Rodriguez-Humbert and her family were never advised to consider repeat testing as new conditions emerged. The diagnosis came unexpectedly, revealing a critical gap in awareness that continues to impact families today. Kaya’s journey was marked by immense medical complexity, including kidney failure, daily dialysis, and intensive treatment. Yet through it all, she remained a source of light—offering gentle smiles, soulful eyes, and a quiet strength that filled hospital rooms with hope.

 

Today, the number of known SPLIS cases has nearly doubled, and Kaya’s life contributed to that progress—not just as a statistic, but as a catalyst for research, awareness, and connection. Her story underscores an urgent reality: rare diseases often affect children and are frequently diagnosed too late. Awareness is not simply about treatment—it is about time. The earlier a condition is identified, the more empowered families are to make informed decisions and advocate for care.

 

Turning Grief into a Movement

In the face of loss, Dr. Rodriguez-Humbert made a defining decision—she chose to build.

Kaya Girl Legacy was created to honor her daughter’s life by planting seeds of knowledge and empowerment in other families. The organization is dedicated to educating communities about the importance of early and repeat genetic testing, particularly as medical science continues to evolve. Kaya’s story is a powerful reminder that genetic conditions do not depend on family history and can affect anyone, often without warning.

 

What began as a mother’s search for answers has evolved into a platform for advocacy, policy engagement, and community education. Through her work, Dr. Rodriguez-Humbert is ensuring that other families are not left navigating complex health journeys alone, without guidance or access to critical information.

 

Entrepreneurship with Purpose

For Dr. Rodriguez-Humbert, entrepreneurship is deeply tied to impact. She is not simply building an organization—she is shaping conversations that influence how families, healthcare providers, and policymakers approach genetic health.

 

Her work allows her to engage in spaces where change is needed, bringing visibility to issues that are often overlooked. It also enables her to create pathways for families seeking access, answers, and support. This form of entrepreneurship is rooted in intention, where every initiative, partnership, and conversation contributes to a larger mission of systemic change.

 

Addressing a Critical Gap in Caribbean Communities

A central focus of Kaya Girl Legacy is expanding awareness and access to genetic health resources within Caribbean communities. In many cases, families are introduced to genetic conditions only after symptoms appear, leaving little room for preparation or informed decision-making.

 

Dr. Rodriguez-Humbert is working to shift this narrative by encouraging earlier conversations around genetic health within families and communities. Her advocacy promotes education, awareness, and access to testing, helping individuals better understand their health and make proactive choices. By bringing these conversations forward, she is creating a cultural shift—from reactive care to informed, preventative action.

 

A Brand That Reflects Life, Faith, and Advocacy

Kaya Girl Legacy is a direct reflection of Dr. Rodriguez-Humbert’s life. Her work is grounded in faith, shaped by motherhood, and driven by a deep commitment to advocacy. She leads with transparency and intention, ensuring that her lived experience remains at the center of everything she does.

 

This authenticity allows her to connect with others in a meaningful way. Whether she is speaking at a university, participating in policy discussions, or engaging with families, her message is consistent, personal, and impactful.

 

Building While Healing

One of the most defining challenges of her journey was building an organization while navigating grief. Entrepreneurship demands clarity and resilience, yet she was simultaneously processing the loss of her daughter.

 

What sustained her was a strong sense of purpose and the belief that Kaya’s life had meaning beyond its time. Through faith and perseverance, she continued to show up—transforming pain into action and advocacy. Her journey serves as a powerful reminder that purpose and pain can coexist, and that even in the most difficult seasons, meaningful work can emerge.

 

A Year of Impact and Influence

In just one year, Kaya Girl Legacy has established a strong presence within the genetic health advocacy space. Dr. Rodriguez-Humbert has participated in national advocacy efforts on Capitol Hill during Rare Disease Week and contributed to the EveryLife Foundation’s Newborn Screening Working Group. She has also been involved in the National Institutes of Health “Save Our Cures” Campaign and contributed to the National Organization for Rare Disorders’ inaugural “Start Genetic Day” initiative.

 

Her voice has extended into academic and medical spaces, with speaking engagements at institutions such as UCSF and Stanford University, as well as participation as a panelist for the American Kidney Fund. Through collaborations with organizations like NephraWare and features across rare disease blogs and podcasts, her work continues to expand in both reach and impact.

 

Collaboration and Collective Impact

Dr. Rodriguez-Humbert believes that meaningful change is built through collaboration. She actively seeks to connect with other women, particularly Caribbean female entrepreneurs, to share knowledge, expand visibility, and strengthen community networks.

 

Her approach is rooted in the idea that growth is not meant to happen in isolation. By fostering relationships and creating opportunities for collaboration, she is helping to build a more connected and empowered ecosystem for women across the region and diaspora.

 

Empowering Families, Shifting Mindsets

The true impact of Kaya Girl Legacy can be seen in the families it serves. Individuals who have engaged with the organization often describe feeling more informed, more confident, and more empowered to take control of their health journeys.

This shift—from uncertainty to informed action—is at the core of her work. It is not only about providing information, but about creating the confidence and clarity needed for families to advocate for themselves and their loved ones.

 

A Vision for Caribbean Women

Looking ahead, Dr. Rodriguez-Humbert envisions a future where Caribbean women are globally influential and deeply connected, leading transformative change across industries. She also recognizes the need for increased access to capital, greater visibility, and expanded leadership opportunities to support that growth.

 

Her perspective reflects a broader understanding that when Caribbean women are empowered, they do more than build businesses—they shape communities, influence systems, and create lasting impact.

 

“I am not just building a brand—I am shaping conversations, influencing systems, and creating pathways for families who need access and answers.”
