Principal Mercy Nazario Cruz
It is both an honor and a privilege to serve as the principal of this incredible school community. At Mark Twain, we believe every child deserves a place where they feel valued, challenged, supported, and inspired to reach their fullest potential. Together, we are committed to creating a school where students thrive academically, socially, and emotionally.
As an educator, I believe that schools are built on meaningful relationships, high expectations, and a shared commitment to excellence. Every student brings unique talents, strengths, and dreams to our campus, and it is our responsibility to nurture those gifts while preparing them to become confident learners, compassionate leaders, and responsible citizens.
Our dedicated teachers and staff work tirelessly to create engaging learning experiences that encourage curiosity, creativity, collaboration, and perseverance. We know that our greatest successes happen when families and schools work together as partners, and I believe that open communication, trust, and mutual respect are the foundation of a strong school community.
This year, as we embrace Richardson ISD’s “Dream On” theme, we are challenging every Mustang to dream boldly, believe in themselves, and embrace every opportunity to learn and grow. Dreams become reality when they are supported by hard work, kindness, resilience, and a community that believes in one another.
It is my privilege to serve alongside an exceptional team of educators who are passionate about making a difference in the lives of children every day. Together, we are committed to ensuring that every Mustang is known, supported, and empowered to succeed.
Thank you for entrusting us with your children. We are honored to partner with you as we build a school community where every student feels a sense of belonging, every family feels welcomed, and every dream has the opportunity to flourish.
I look forward to an incredible year as we continue to Dream On, grow together, and celebrate the success of every Mustang.
With Mustang Pride,
Dr. Mercy Nazario

I am incredibly honored to serve as the Assistant Principal at Mark Twain Elementary. It is a true privilege to work alongside our dedicated staff, amazing students, and supportive families as we create a school where every Mustang is encouraged to learn, grow, and dream without limits.
With more than 20 years in education, I have had the privilege of serving students, families, and educators in a variety of roles, including classroom teacher, instructional leader, parent engagement specialist, dean of students, and campus administrator. These experiences have strengthened my passion for building positive relationships, supporting teachers, and creating a school culture where every student can thrive.
I earned my bachelor’s degree in Liberal Studies with bilingual certification from California State Polytechnic University, Pomona.and my Master’s degree in Educational Leadership and Policy Studies from The University of Texas at Arlington.
At Mark Twain Elementary and as a servant leader I am committed to fostering a positive, inclusive culture where students feel safe, respected, and empowered to become their very best. I also believe that our greatest successes happen when educators and families work together with a shared purpose. I look forward to partnering with our Mustang families as we celebrate achievements, overcome challenges, and create meaningful learning experiences for every child.
Outside of school, I enjoy traveling, exploring different cultures, spending time with my family, and making memories with those I love. These experiences remind me to embrace curiosity, celebrate diversity, and continue learning every day.
This year, as we embrace our district’s “Dream On” theme, I hope to inspire every student to believe in themselves, every teacher to continue making a difference, and every family to know they are an essential part of our Mustang community. Together, we will dream big, work hard, and make this an unforgettable year for every Mustang.
Your Proud Assistant principal,

Every child deserves a champion, every family deserves a partner, and every dream deserves the opportunity to grow.
