Our Team


Ambika Dani

CEO / Superintendent

Ambika Dani began teaching when she was 14 years old, in Lagos, Nigeria, when she gathered a group of underserved children in the living room of her apartment to help supplement the education they were receiving. Since that summer of teaching children on mats in her living room, she has dedicated herself wholly to education and to ensuring that children everywhere have equal access to the quality education they deserve.


Ambika comes from a strong mathematics background. During her undergraduate years in college, she provided SAT tutoring and additional after-school support to low-income students of all ages on a volunteer basis. Following her graduation from Columbia University with a bachelor’s degree in mathematics, she spent six years teaching math at the elementary, middle, and high-school levels in both charter and private schools. Two of the schools she taught at, THINK Global School and Saint Ann's School, have been recognized as two of the most innovative schools in the United States. These opportunities helped her recognize high-quality, effective instruction and made her further appreciate how rare it is. In 2015, Ambika returned to Columbia University to pursue a master’s degree in mathematics education from Teachers College in order to further improve her teaching practice.

As Ambika worked to found Promesa Academy, she was a New Schools Creation Fellow with the High-Tech High Graduate School of Education. Ambika continues to seek out opportunities to learn from schools around the country that are being truly innovative and student-centered to help inform the vision for Promesa Academy.

Casandra Reyes

Casandra Reyes

Director of Operations

A native South Texan, Casandra Reyes was the first in her family to graduate from college. She comes from a family with a mother who worked incredibly hard to support her and her three siblings and who always instilled the value of a strong work ethic.

She studied Fine Arts, Graphic Design, and English at Texas A&M University in Kingsville.

Casandra believes that despite any socio-economic background or resources, all students deserve the right to quality education. At Promesa, Casandra hopes to help build an environment that cultivates the same love for learning that she was fortunate enough to experience growing up. When away from the office, you can find Casandra baking away or acting as an advocate for animal rights.

Mary Hoekje

Director of Curriculum & Instruction

Mary has worked as a K-2 bilingual and dual language teacher on the Southeast side of San Antonio for four years. She grew passionate about education at a young age as she saw the many ways her parents shared their love of learning and passions with her and others. Her mother was a dancer and her father worked in the trades and both spent ample time teaching and learning from the community. As a result, Mary grew into a person who also felt called to share her passion with others and to support her community through public service. For her last four years as an educator, Mary became deeply invested in the community and families she served on the Southeast side of San Antonio and grew professionally to develop into a curriculum writer, mentor, and coach for new teachers.

Mary's deep connection to the communities she has taught in and her desire to change the inequities that persist in education also led her to co-found SA RISE in 2016. At SA RISE, she led grassroots community organizing efforts around education all across San Antonio.

Mary deeply believes in social-emotional development and wellness as a building block for the success of every learner and is dedicated to finding creative solutions to support every student and every teacher she encounters. Her strong linguistics background, having majored in Spanish with a minor in Latin American Studies and tutored English while living abroad, and her experience in the classroom has helped shaped how she envisions what excellent teaching, classrooms, schools, and support look like and feel like and deeply influence how she plans to support learners and teachers as Promesa Academy's Director of Curriculum and Instruction.


Anna Bathgate

1st Grade Math Teacher

Anna Bathgate has been a high school math teacher near San Bernardino, CA for the last 11 years. She was a founding member of her current high school and the math lead for the last 5 years. In her previous role she also worked on the development of high school curriculum and vertical alignment with lower grades. She has a Bachelors in Math and a Masters in Curriculum & Instruction with an emphasis in Language and Culture. In addition to teaching students, Anna has been able to speak to members of the California Mathematics Council on how to use technology to develop a growth mindset in students.


A high school teacher, Anna has worked to shift the fixed mindsets of her students from believing their math ability is something they are born with, to realizing their ability is something that can grow through reflection, perseverance, and authentic learning opportunities. There is no better time to instill this in students than when they first begin their math careers, so Anna is excited to be able to develop a strong foundation in mathematics with Promesa's students. A big misconception in math is that there is only one way to an answer, but the truth is that when creativity is let free there are an endless number of approaches. Anna is looking forward to sharing her content expertise with the families at Promesa so that they can see the big idea of where their learning is going to take them in the future.

Outside of the classroom, Anna's priority is spending time with her family, which includes her 3 children. She is an avid reader, enjoys cooking, and exploring the outdoors.

Breanna Cadena

School Counselor

Breanna Cadena is a National Certified Counselor and a current Licensed Professional Counselor (LPC) Associate. Originally from the Rio Grande Valley, Breanna recognized a stigma towards “mental health” amongst her community and decided to be a part of the movement towards destigmatizing the term.

Breanna moved to Austin in 2015 to attend The University of Texas at Austin where she pursued a B.A. in Psychology. From there, Breanna moved to San Antonio in 2018 to pursue a Masters in Clinical Mental Health Counseling at The University of Texas at San Antonio. While pursuing this degree, Breanna furthered her passion for helping others who would not get help otherwise. She felt it necessary to help psychoeducate and find resources for those who did not even recognize help was available. She is well aware we are far from destigmatizing the term “mental health” completely but believes students are the population to begin with so we can build a community surrounded in empathy.


Breanna recognizes how important it is to have these conversations and build relationships with not only our students, but their families as well.

She is incredibly excited to begin her counseling journey here as part of the founding team!
