Her Story

About Shannan

My career has been shaped by a passion for languages, advocacy, and understanding how people learn. I began my academic journey at the University of Texas majoring in Chemical Engineering while interning at the Mexican Consulate, where I aspired to become a diplomat. Language acquisition and cross-cultural communication came naturally to me, and I envisioned a career dedicated to building bridges between people and nations.
Life took me in an unexpected but deeply meaningful direction when I became a single mother. Determined to provide for my family while making a difference, I earned my alternative teaching certification and spent the next two decades as a bilingual educator serving multilingual students with diverse learning needs. Working closely with these children ignited a passion for special education and exposed me to the significant challenges bilingual students often face in receiving accurate, culturally and linguistically appropriate evaluations.
This passion led me to pursue a Master of Education in Special Education, where my interests shifted beyond instruction and toward the clinical and neurological aspects of learning. I became increasingly fascinated by the complexities of cognition, language development, executive functioning, and the ways disabilities can be masked—or misidentified—in second-language learners.
My professional mission became deeply personal after my youngest son was born with a congenital heart defect that resulted in an intellectual disability. Navigating his medical and educational journey strengthened my commitment to understanding the neurological and cognitive foundations of learning and fueled my desire to become a Licensed Bilingual Educational Diagnostician.
Today, I combine more than 20 years of classroom experience with specialized expertise in bilingual assessment, cognitive evaluation, and special education eligibility. My work is driven by the belief that every multilingual learner deserves an evaluation that distinguishes language difference from disability, recognizes individual strengths, and provides equitable access to the supports necessary for lifelong success.


Her Interview

Ten minutes with Shannan

01What do you attribute your success to?

I attribute my success to resilience, curiosity, and a genuine commitment to serving others. My career has never followed a straight path, but each challenge has strengthened my purpose. Becoming a single mother taught me perseverance and adaptability. Teaching bilingual students for more than 20 years taught me patience, creativity, and the importance of meeting people where they are. Raising a son with complex medical and developmental needs deepened my empathy and inspired me to understand the cognitive and neurological foundations of learning on a much deeper level.

Throughout every stage of my career, I have remained committed to lifelong learning and to advocating for those whose strengths are often overlooked. I believe success comes from combining knowledge with compassion, asking difficult questions, and never settling for "good enough" when a child's future is at stake. My greatest accomplishments have come from helping multilingual students receive accurate evaluations, appropriate services, and opportunities to reach their full potential. That purpose continues to motivate me every day.

02What’s the best career advice you’ve ever received?

The best career advice I've ever received was to never stop learning. Every role I've held—from bilingual teacher to educational diagnostician—has required me to grow, ask better questions, and challenge my own assumptions. Education, neuroscience, and language acquisition are constantly evolving, and I've learned that expertise isn't about having all the answers; it's about being willing to keep learning.


I've also learned that your greatest challenges can become your greatest strengths. Some of the experiences that shaped me most—raising a child with complex needs, navigating life as a single mother, and working with multilingual students who were often misunderstood—ultimately gave me a perspective that has made me a stronger advocate and a better professional. Those experiences taught me that purpose and persistence are often more valuable than a perfectly planned career path.

03What advice would you give to young women entering your industry?

Never underestimate the value of your voice, your curiosity, or your compassion. Education is far more than delivering instruction or administering assessments—it is about changing the trajectory of a child's life. Ask questions, seek mentors, and never stop learning. The fields of education, psychology, and neuroscience are constantly evolving, and the professionals who make the greatest impact are those who remain open to new research and better practices.

I would also encourage young women to trust their instincts while remaining open to collaboration. Don't be afraid to advocate for students, especially those whose voices are often overlooked, even when it means challenging the status quo. Build your expertise, let integrity guide your decisions, and remember that your career doesn't have to follow a straight line. Some of the most meaningful opportunities will come from unexpected experiences. If you stay focused on serving others with excellence, empathy, and courage, your influence will extend far beyond the classroom or evaluation room.

04What are the biggest challenges or opportunities in your field right now?



One of the greatest challenges in education today is ensuring that multilingual learners receive equitable and accurate evaluations. Too often, language differences are mistaken for disabilities, while genuine disabilities can also go unrecognized because they are masked by second-language acquisition. As our student populations become increasingly diverse, there is a growing need for culturally and linguistically responsive assessment practices, highly trained bilingual professionals, and evidence-based decision-making.
At the same time, this presents one of our greatest opportunities. Advances in cognitive science, neuroscience, and educational technology are giving us a deeper understanding of how children learn and how to identify their unique strengths and needs. By combining research with culturally responsive practices, we can provide more accurate evaluations, reduce disparities in special education identification, and ensure that every child—regardless of language or background—has access to the support they need to thrive. For me, that opportunity is both professionally exciting and deeply meaningful.


05What values are most important to you in your work and personal life?

Integrity, compassion, curiosity, and perseverance are the values that guide both my professional and personal life. I believe integrity means doing what is right, even when it is difficult, and ensuring that every decision is made in the best interest of the children and families I serve. Compassion reminds me that every student has a unique story, and every family deserves to be treated with dignity, empathy, and respect.

I also value lifelong learning. Whether I'm studying advances in neuroscience, bilingual assessment, or educational practices, I believe there is always more to learn and that growth comes from remaining curious and open-minded. Finally, perseverance has shaped every chapter of my life. The challenges I've faced—as a single mother, an educator, and the parent of a child with complex medical and developmental needs—have strengthened my resolve to advocate for others and to approach every obstacle with resilience, hope, and purpose. Those values continue to influence not only how I work, but also how I strive to live each day.
