The Impact of STEM Education: How Mentorship and Community Changed My Life

By: Jescely Castillo


I was unaware at the time but attending one of the nation’s first K-8 STEM schools would change the trajectory of my life. Before attending, I excelled in mathematics but struggled with behavioral challenges and lacked motivation. I frequently found myself involved in fights, bullying, and disruptions, accumulating suspensions and disciplinary charges. It would have been easy for others to dismiss me as a lost cause. However, everything changed when I encountered mentors and entered a school environment that was deeply committed to STEM education.

Discovering My Passion in STEM 

Through Problem-Based Learning, I shifted from simply recognizing my talents in math, science, and engineering to developing a strong personal connection with career pathways. I began to see myself reflected in the career lenses we explored through projects, the guest panelists who shared their specialties, and the wide range of career options we were exposed to. These experiences shaped my identity as someone who belonged in STEM, and that sense of purpose carried me through my college journey.

The Power of Mentorship

One individual who had a profound impact on my journey was Kellie Lauth, MindSpark’s CEO. Her kindness and support were instrumental—she invited me to speak at community events representing our student body, honored me with a school ambassador uniform, and encouraged me to mentor and tutor others.


Kellie also introduced Problem-Based Learning at the K-8 and high school I attended, STEM Launch and Northglenn High School STEM, which ignited my passion for STEM among many of my peers and inspired my deep involvement with the community.  


Continuing My STEM Foundation

In high school, I continued building on this foundation through advanced coursework, leadership roles, and hands-on projects. I pursued my passion for engineering by completing a four-course engineering elective program and studying up to Calculus III, earning college credits along the way. I also led fundraising efforts for events like Girls Only STEM Day, which gave young women the opportunity to connect with professional engineers and explore career options.

One of the most impactful experiences was my senior capstone project—creating a tactile keyguard for students with disabilities. Collaborating with industry partners, my team designed and manufactured a communication tool that provided students with motor and visual impairments more independence, a moment that deeply solidified my belief in STEM’s ability to solve real-world challenges.


Through my mentors and educators, I was offered an internship at MindSpark, where I further developed practical skills. I gained hands-on experience managing social media content, earned relevant certificates, and participated in professional development sessions. These experiences not only enhanced my career prospects but also allowed me to inspire educators and advocate for STEM education.


A Successful Transition to Higher Education

My experiences with MindSpark and STEM programs significantly prepared me for college, equipping me with the skills to engage confidently with professors, collaborate effectively in team projects, and communicate my work at a high level. I entered college ready to contribute meaningfully because I had already experienced real-world problem-solving, teamwork, and professional presentations during my time in these programs.


These experiences propelled me into college, where I became a first-generation mathematics and biomedical engineering graduate. During college, I served as a peer tutor at The Institute for Learning and Teaching at Colorado State University, pioneering tutoring services specifically supporting underrepresented students. 


I also joined the Ram Handler team, caring for CAM the Ram, CSU’s live mascot. As the only Spanish-speaking handler, I had the privilege of connecting with first-generation families at community events, sharing CAM’s story, and fostering a sense of belonging for families like mine. These opportunities not only helped me refine my leadership and communication skills but also reinforced the importance of mentorship and community—values that continue to guide me today.


The Impact of Educators

Students like me often lack professional networks when they enter the workforce.

For us, teachers are the most valuable advocates. Teachers know their students personally, understand their strengths, and are invested in their growth. They open doors that would otherwise remain closed.


Even after my college graduation, I reached out to my mentors and K-12 teachers because I knew they had built networks that could connect me to opportunities I wouldn’t have found on my own. My teachers and mentors mobilized, offering guidance, recommendations, and introductions.

Thanks to their encouragement and connections, I eventually landed interviews and secured a job with their recommendation. Their unwavering belief in me not only began my professional career but also reinforced the value of having educators who are deeply invested in their students’ long-term success.


If every student had a teacher with strong industry connections, the doors to internships, mentorships, and career advancement would swing open, creating lasting opportunities.


My Journey Today

Today, as the Development and Design Specialist at MindSpark Learning, I leverage my lived experience to advocate for STEM education and mentor the next generation of learners. Programs like those at MindSpark equip teachers with the tools they need to build these critical connections. 


Investing in educators means ensuring that students—especially those from marginalized backgrounds—have access to the same opportunities that changed my life.
