Dr. Charles Reininger, Jr., Principal
I am Dr. Charles Reininger, Jr. and the proud principal of Reagan High School. I was formerly the principal at Tex Hill Middle School for five years and was at Churchill High School prior, where I served as assistant principal for two years. Before WC, I started my NEISD journey as an assistant principal at Bush Middle School from 2008-2015.
San Antonio born, I am the eldest son of five children by Charles and Carolyn Reininger, Central Catholic and Providence graduates. I am the fortunate husband to Sandra Garza Reininger. We have two children, Nicholle and Charles III. Tennis is a large part of Sandy's world beyond her extraordinary devotion to her family, and I am an avid saltwater fisherman and enjoy hunting and playing golf. I came to NEISD after 17 years as a teacher, coach, counselor and administrator at the Marine Military Academy in Harlingen, Texas, and one year as a middle school campus assistant principal in Alice, Tx. I maintain Texas educator certification in teaching, counseling, principalship, and superintendency. I lettered in track & field at the University of Texas Austin, earned a BA (Speech Comm, English) and an M.Ed. (Counseling) from the University of Texas-RGV. I completed doctoral studies at the University of Houston in Curriculum and Instruction.
I am an energetic, gregarious, and serious individual who believes that there is no more important vocation than actively participating in the development of our youth. I believe in a team concept and am collaborative, respectful, and demanding. I believe in delivering a positive and caring attitude, and in implementing best practices through a “360 Degree” approach to developing our students.
I encourage your student(s) to participate in their high school experience as fully as possible. During this time of exploring and honing talents and passions, we look for them to develop a sense of pride in their efforts and in representing Reagan High School. I would also encourage and invite parents to actively participate in their student’s education by joining our Reagan PTA and keeping aware of the various opportunities for volunteering.

Mr. Brian Brookhart, Asst. Principal
It is truly an honor to join the family at Reagan High School!
I moved to Texas in 2022, where I served as an assistant principal at Dripping Springs before coming to NEISD. Prior to that, I had spent my entire career in the Northeast Ohio area first as a band director and then as an administrator. I had the unique privilege to serve as assistant principal in the town I was raised in - Aurora, Ohio (Go Greenmen!) - and it was there that I learned just how important all stakeholders are in building a culture that can provide incredible opportunities for students.
Similar to a band, I view the school community as a group of dedicated partners who produce their greatest results when they work together in harmony. I look forward to the opportunity to support the students of Reagan High School in their educational journey, and to work with all stakeholders to maintain the strong culture of excellence that is clearly already present in Rattler Nation.

I began my journey with NEISD eleven years ago as a History teacher and coach at Tejeda Middle School. After Tejeda, I moved to Johnson High School where I coached basketball and track for three years.
An opportunity arose which allowed me to stop coaching and I was able to move into the role of Student Council sponsor and the Spirit Assistant where I helped dance and cheer.
I am excited to act as an assistant principal at Ronald Reagan! I look forward to working with the staff and community to provide the best education to all students who attend Ronald Reagan.

I look forward to collaborating with parents, staff, and the entire Reagan community to build upon our shared foundation and ensure this school year is one of exceptional achievement, growth, and pride.

Mr. Mark Soppe, Asst. Principal
I have always enjoyed helping others grow and excel. That has been the driving force behind my educational career. The field of education has allowed me to make a difference in the lives of all the students I have had the opportunity to mentor, grow and exceed expectations that they thought could not be achieved. It is what continues to instill in me a passion to foster life-long learning and leadership in my students.
Having grown up in a small town in Iowa I knew that I needed to see more of the world. My first teaching job was at Widefield High School in Colorado Springs, Colorado teaching business courses. After eight years my family was offered an opportunity to move to Germany which we could not pass up. While in Germany I was hired as the Unit Training Manager for NAF on Ramstein Air Base and I taught Master’s level courses at the University of Phoenix on base.
When we moved back to the states, I spent two years teaching graphic design at Freedom High School in Woodbridge, Virginia. Finally, we moved to Texas where I have been at Reagan High School ever since.
It is an honor and privilege to be part of the administrative team at Reagan and I look forward to belonging to a leadership team that grows the greatest staff and students in San Antonio.

Ms. Jennifer Esparza, Asst. Principal
Hello Rattler Community!
My name is Jennifer Esparza, and I have over 25 years of dedicated experience in
education. My journey began in my hometown of Abilene, Texas, where I attended public
schools and later earned three degrees from Hardin-Simmons University: a Nursing
degree, a Bachelor of Arts in Spanish and Biology, and a Master of Education in Counseling
and Human Development. Go Cowboys! I later completed my Principal Certification
through Lamar University.
My career in the classroom started at Abilene Wylie High School, where I taught Spanish for
five years. In 2004, my family relocated to San Antonio, and I proudly embarked on my
NEISD journey right here at Reagan High School. I spent years teaching here at Reagan
before transitioning into campus administration. Through these roles, I have learned the
unique expectations of this community, and I know this is exactly where I want to continue
to serve. Reagan has a long tradition of excellence built on quality instruction, strong
leadership, and a community that deeply values and supports its school.
As an educational leader, I practice servant leadership grounded in empowerment and
supportive environments. While I deeply value traditional values, I always look toward
improvement and innovation. It is vital to honor our past, recognize our present, and
envision our future. It is my duty to ensure the well-being, growth, and success of all
students and my fellow colleagues through a shared commitment to lifelong learning—and
I am here to serve!
On a personal note, I am a proud NEISD parent. I have been blessed with four children and
have had the privilege of watching two of them walk across the NEISD graduation stage. My
two younger children are currently in high school, and we look forward to watching them
walk that same stage very soon! I truly love the NEISD community and feel honored to be a
continuous part of it.

I started teaching in 2004 and taught English and Social Studies before becoming an administrator, where I have served in a variety of roles.
I am incredibly passionate about our profession and Reagan's mission. I look forward to working with and serving the students and families of Reagan High School!
