MIND

BODY

SPIRIT

Our classrooms are small, multi-grade environments. They are structured in schedules and routines. Daily content and expectations are based on developmental learning. Because of our small class size, students are privileged to receive more one-on-one instruction and thus progress through their studies more efficiently. Having multi-grade environments allows for leadership, reinforcement of learning and skills, and creates strong relationships between the

faculty and students.

Exercising and learning to care for our bodies is an important aspect of education. When the body is strong, the mind is strong, and then the spirit will be strong also. All age groups go outside for fresh air, exercise or free play at least once a day. Science classes emphasize nutrition, how our bodies work, and how to keep our bodies strong for the service of God.

Each class taught at HAA is done so with Christ-focused instruction. Jesus is invited into the classroom each day as we begin with worship. Special chapel presentations take place each Friday, and a Week of Prayer service is scheduled once per semester. Community service activities, spirit week, and prayer buddies are also emphasized within the curriculum.

ROMINA REGALADO

Position: Pre-K & Kindergarden

I feel it is my mission to minister
to children in this capacity and it goes beyond my job description. I have had the pleasure of teaching at Houston Adventist Academy. Our school is home and family to me, there is no other way about it! I love our school and our students and their families. Serving here has been my greatest pleasure

SONNYA 
MOSQUEDA

Position: 5th & 6th Grade Teacher

“Become a teacher,” I was told more than once.  My answer was always, “no way!”  Here I am, 15 years of teaching in the public and private sectors plus 2 years of homeschooling my own and others, doing what God has loudly asked me to do.  I look back and don’t see myself doing anything else!  From Pre-K to 8th graders, God has lead me to not only teach, but be taught!  Children have that effect, you know, and every year I learn to become a better teacher because of my students... aka “my kids!”

STEVE ESTRADA

Position:  Mathematics 

What Students can expect from my class is to walk into a classroom in which students aren’t afraid to ask questions. Parents can expect their kids to learn to depend on God to understand the material and improve in their math skills. What separates me from other educators, probably my experience teaching abroad.

SARAI

GONZALEZ

Position: 3rd & 4th Grade Teacher

As a little girl, I dreamed of becoming a teacher one day. I made that dream a reality in 2012 when I graduated with a degree in education from the University of Houston-Downtown. graduated with a Master degree in Curriculum and Instruction from Houston Baptist University. I believe communication is key in a successful classroom. I like to keep parents informed and up to date about events, grades, struggles, and victories. I believe my communication with students is just as important. Students will know what is expected of them at all times, and what we will do to achieve our goals. They will also know they are loved and cared for by their teacher.

GABRIEL LARRIU

Position: Physical Education Teacher/Director of Athletics

In my class students can expect to think critically. It is of great importance that a student learns how to think.

We use biblical teachings and stories and make them relevant to us now.The end of goal of a Coach Larriu taught class is not content mastery, rather Christ character mastery. We can have all the knowledge in the world but with out Jesus we have nothing

I promote group collaborations and discussions. Most importantly I require my students to be responsible and hold them accountable for their work and their actions. We are all in this together!
