    P-TECH Assistant Principal


    Office Location - Room 160D

    Hello and Hola! My name is Ralph Spencer, Jr. and I serve as the Sunset P-TECH Assistant Principal. I have been blessed to work in the field of Education and Student Support for approximately 25 years, which includes my work in the college area as well as secondary public schools. My personal mission is to use the talents, skills, and experience I have been blessed with to provide the needed support for young people to grow up educationally and personally. My parents and so many others invested so much in me and it is my priority to make every effort to do the same for the young people I have an opportunity to work with. It is what our Sunset P-TECH students call.."THE COLLEGIATE WAY". Thank you in advance for being a part of our growing greatness.



    Dr. Tamara Robison, Ed.D.

    P-TECH Workplace Learning Coordinator 


    Office Location - Room 160C

    My name is Tamara Robison and I serve as the Sunset P-TECH Workplace Learning Coordinator. My goal is to ensure every student who enters and leaves this organization is properly prepared for their future careers.  This includes having a current resume, industry certifications, proper interview skills, internship and job shadowing opportunities.  If I have exposed students to their many possibilities, then I have done my job. 

    I have used the quote "Education is the movement from darkness to light" by Allan Bloom to guide my educational path. When I first made my career change from business to education, I found joy in seeing “the light bulb” go off as students gained understanding. I loved the idea of exposing my students to new and exciting perspectives in my English class. I have been in education for 20 years now and there has never been a dull moment.  Now as the Workplace Learning Coordinator, I am able to work with our Industry Partners to bring engaging academic activities to our students, making it a real-world experience.

    I have experienced an amazing journey in my career as an educator. I believe that if you do something that you enjoy doing, you’ll never work a day in your life.  I truly enjoy what I do and the opportunities that I have to help students, their families, and the community as a whole.

    Mr. Andrew Kirk

    AP Human Geography


    My name is Andrew Kirk, and I am the AP Human Geography teacher for our P-TECH here at Sunset. I am a native Dallasite, fifth-generation Texan, and proud Dallas ISD alumnus (Woodrow Wilson, '06). I attended Southwestern University, graduating with a double-major in German and History. Afterward, I began Georgetown University's MA program in Global, International, and Comparative History, where I specialized in an empire and historical memory in Southern Africa. I examined the role of memory in shaping public space, foreshadowing my career as a geography teacher. After I graduated, I completed a term of service in AmeriCorps with Reading Partners, a literacy intervention nonprofit then working in collaboration with Dallas ISD. This experience led me to pursue a career in public education, and I applied (and was accepted) to Dallas ISD's Alternative Certification Program.  I accepted my first teaching position here at Sunset in 2014, and I've been here ever since. I love Sunset, and I'm very excited to be a part of our newly launched Collegiate Academy. I look forward to seeing the Collegiate Academy further enrich our school's learning environment, preparing our students for post-secondary education while equipping them with cultural literacy in an increasingly interconnected world. 



    Ryan McKelvy, M.A.

    World History Honors


    Room 166

    Education: Bachelor of Arts in History, 2012, and Master of Arts in History, 2016, from Midwestern State University.

     I was raised in North Texas and lived for some time in Dallas before graduating from Rockwall High School in 2008. I then returned to my hometown of Wichita Falls to attend Midwestern State University (MSU). At MSU, I majored in History with a focus on Modern European History and minored in Political Science. I completed the last two classes of my undergrad studying abroad at Queen Mary University of London in the Summer of 2012. I graduated later that Fall and was able to teach American History for 2 years while working on my master's degree. In 2016, I graduated from Midwestern State University with a master's degree in History, focusing on American Western History. 

    After a few years in the public sector, I decided to pursue my original calling of being a teacher. I began my endeavor at Houston’s Westfield High School in 2019 where I taught everything from Government/Economics to World History to Dual Credit US History. In 2022, I made the decision to move to Dallas and was fortunate enough to join the Sunset P-TECH team where I currently teach World History Honors. I look forward to growing with the Sunset P-TECH P-TECH ECHS and making sure my students are ready for Dual Credit US History next year.

    Mr. Jaime Govea

    Name: Jaime Govea
    Title: P-TECH 11th-grade Team Lead
    Subjects: Physics (On-level, Honors, AP)
    Email: jgovea@dallasisd.orgEducation: Bachelor of Science in Physics with a minor in Mathematics and Education from the University of Texas at Arlington
    Description: I teach to repay my debt to society and gave gratitude to the state and country that lifted me from poverty. Teaching is my way of saying thank you. My childhood dream of becoming a Physicist has been achieved. It is now my turn to ensure today's youth have the cognitive skills to achieve theirs. When I am not teaching, I continue to learn. I do this by reading philosophy, foreign languages, architecture, and other STEM-related books. I journal and sketch ideas. What drives me to continue learning is my curiosity for different ways to solve the world's issues and improve existing designs.
