Mr. Sambrano

Hello parents and students my name is David-Ryan Sambrano, and I am very happy to be apart of San Marcos High School. I am apart of the social studies department and I will be teaching Academic World History this school year. With the current situation of online learning, All assignments will be on my Canvas page.

About me: I am a born and raised San Marcian. I graduated from San Marcos High School in 2010 and then received my Bachelors from Texas State University with honors. I love sports, and anything with physical activity. I coach Freshman Football, and I am the Varsity Assistant for the Rattler Baseball Team. I am proud to be home at San Marcos High School and I truly enjoy teaching Social Studies, which allows me to broaden students horizons. 

  • Online Learning: Students I will be publishing a weeks worth of work starting on Monday. As long as you get all work finished then you will be done for the week. It allows you to work on your own time and not be overwhelmed. However, on Friday, we will have a discussion question you need to check in and do on only friday. Make sure you are getting into canvas on our alloted class time, and you will have a video conference on if you need to ask me any questions during our class time.
