Rex Lees has been inspiring his students at Emmett J. Conrad High School since the fall of 2021 with a passion that reaches far beyond the classroom walls all the while also inspiring a community-wide love of STEM education.

“We are the FIRST Robotics Competition UIL State Champions for the second year in a row!” he said.
Under his leadership, the club has expanded to supporting projects, such as the “RoboChargers for All” campaign, which promotes inclusion and diversity in robotics and STEM through specialized camps run by female mentors with the goal of encouraging all students to go into the field of engineering.
“We hold robotics camps specifically for girls and non-binary students, led by female mentors, to show that anyone can become an engineer,” Lees said.
Lees’s journey with Dallas ISD led him to join the renowned 3005 RoboChargers, a For Inspiration and Recognition of Science Technology (FIRST) Robotics Competition team. Established in 2009 and revitalized in 2013, the RoboChargers compete across the state, inspiring students from diverse backgrounds to pursue careers in engineering and technology.
“3005 RoboChargers was inspired by the need for technologically savvy workers in and from the Vickery Meadows area,” Lees said. “Our goal is not only to win competitions but also to excite STEM education, particularly within Dallas.”
For Lees, education isn’t just a career choice; it’s a familial legacy.

“Education has been in my blood,” he said. “All my grandparents were educators, and my mom still is. Both of my grandmothers were nationally recognized math teachers in their time.”
The club’s activities are as diverse as its members, ranging from computer aided design and programming to fabrication and outreach. Another important factor of the club’s activities is the collaboration with external organizations and professionals.
“We have 10+ professionals from various fields who volunteer their time to work with the students,” Lees said. “From manufacturing to programming, our students gain invaluable experience from these partnerships.”
Through hands-on experience and mentorship, students gain practical skills and knowledge essential for their future endeavors.
“Students have direct access to and interact with professionals as they solve problems together,” Lees said. Some of the club’s volunteers come from Texas Instruments, REV Robotics and Cisco.
The impact of the club extends far beyond technical skills. Lees notes a transformation in his students’ attitudes and behaviors.
“Many robotics students start as introverted quiet kids,” he said. “But throughout the program, they develop confidence in themselves and their abilities.”

The robotics journey hasn’t been without its challenges. The pandemic forced the club to reset, with Lees and a handful of students starting fresh in the 2021-2022 school year. The club has grown exponentially since then, fostering a culture of teamwork and inclusivity.
Lees’s reflection on his time with Dallas ISD shows his passion for education and robotics.
“Seeing my students’ successes and witnessing their enthusiasm for STEM education is my favorite memory,” he said.



“Rosa Castillo is our BEST parent volunteer who always goes above and beyond to serve the needs of our [team members], students and families. She always has a smile on her face and is quick to help at a moment’s notice. Not to mention, she is very creative and always has new ideas to offer to help improve our school atmosphere.” said Catherine Gonzalez, counselor at Julius Dorsey Leadership Academy. Castillo was recently nominated as Julius Dorsey Leadership parent for Dallas ISD State of the District. Besides being an exceptional role model and helping with the North Texas Food Bank, she has formed a gardening club with parents and students. “This school year there was a turnover in our parent organization and they went from being a PTO to a PO, which meant they were no longer able to fundraise. This didn’t stop Ms. Castillo, it only made her work harder to seek donations from other parents and the community to help meet school needs. Ms. Castillo used this as a way to introduce herself to new mothers on our campus (especially immigrant mothers) to make them feel welcome and encourage them to volunteer at our school. She was able to form a new Parent Organization with new mothers who, through donations, have been able to provide student and [team member] incentives for holidays, as well as for special events like the total solar eclipse!”
