Henry H.

Henry H. is a certified educator with a deep commitment to helping students thrive academically and personally. Born and raised in San Antonio, Texas, he earned his Bachelor of Arts in Interdisciplinary Studies and a Master’s in Business Administration from The University of Texas at San Antonio (UTSA).

A lifelong sports enthusiast, Henry grew up participating in basketball, soccer, track, and cross country, and he remains an avid runner to this day. It was during his time at UTSA that he discovered his passion for teaching and mentoring young people, which led him to a rewarding career in education.

Henry began his career sharing his love for mathematics and sports, coaching a variety of indoor and outdoor sports at the middle school level and mentoring high school athletes in distance running. He has a particular interest in helping young athletes balance academics and sports to achieve their full potential.

In addition to coaching, Henry spent several summers working with the Pre-Freshmen Engineering Program (PREP), which introduces middle and high school students to STEM fields through hands-on experiences. This role further fueled his passion for teaching, and he has since dedicated time to tutoring and mentoring students one-on-one, primarily focusing on math, but also supporting broader academic growth.

Henry believes that building strong, trusting relationships with his students is key to fostering their success. He continues to refine his teaching and mentoring strategies, finding the process deeply rewarding as he helps students overcome challenges and reach their goals.

“I believe that every student has the potential to excel, and my role is to guide them toward realizing their own abilities. Education isn’t just about knowledge—it’s about building confidence and curiosity. By creating a supportive, engaging environment, I help students unlock their full potential and develop a lifelong love of learning.”

Steven O.

Sometimes in life the good lord lets you go 360 degrees, then brings you back where you belong. My dad successful businessman laid a great foundation for me to follow in his footsteps. After 3 unsuccessful attempts, I ended up stopping at the catholic chancery seeing a hiring teachers sign. This is where I began my teaching career. 25 years later I retired from San Antonio college loving every minute of teaching. My engaging personality is one of the keys to my success. The other was a fierce loyalty to my students and their success. Helping students is where I needed to be, and it is where I want to be.

I am knowledgeable and patient and am passionate about helping students be successful. I enjoy helping each student be successful in math and to increase their confidence and achievement. I am excited to be able to help students and know that the results will be significant. My outside interests are distance running, walking, watching sports, music and spending time with my family.

Jordan G.

Jordan is certified through the Texas Education Agency in Mathematics, grade levels 4 through 12. Jordan has 10 years of experience teaching in the public school system, charter school system, and private tutoring. His experience is with mostly middle school and high school grade levels (6th-12th). In today’s education world, students are being asked to problem solve using algebra at younger ages. This is why students must be mathematically prepared for whatever their future holds, whether it is scoring better on college entry tests or daily at whatever skill they seek to pursue.

Jordan is a Marine Corps veteran, but don’t worry, he’s actually one of the smart ones! Seriously though, Jordan is very sincere and passionate about mathematics and connecting/teaching students. Jordan discovered that this was his God-given purpose in life during his time as a youth minister at his home church for 2 years, soon after being honorably discharged from military service. Jordan looks forward to serving the community by assisting students to develop a growth mindset and a passion for the most important topic in school, MATH! Although, Mr. Guerrero is somewhat biased in this opinion!
