Mr. Oscar Velasquez

Welcome to AP/Dual Credit Biology...My name is Oscar Velasquez and I will be your Guide, Jedi Master, Instructor, and Teacher for the course.  This year will be my 17th year teaching and 13th year teaching AP Biology.  I started my teaching career at Reagan High School but moved to Johnson when it open it's doors in 2008.  I graduated from the University of Texas at Austin (Hook'em Horns) with a BS in Molecular Biology and a MA in Science Education.  Additionally, I am part of only a few Certified Master Science Teachers in the District.  I am married to a beautiful and smart Baylor Bear Christine Velasquez, who used to teach at Johnson but now tutors math at home...I have three amazing kids Ellie, Lucas, and Darwin.  

On my free time (not much during the school year) I enjoy watching Football (Go Horns, Go Cowboys) and Basketball (Go Spurs Go).  I also enjoying collecting comics, listening to music, watching movies, and reading non-fiction material (all things science).  I am a huge "Star Wars" fan ("Empire Strikes Back" favorite) and a Marvel Studios Fan ("Avengers Infinty War and Endgame" favorite BUT also Avengers: Assemble...Overall SuperHero Fan).  My favorite shows are "Parks & Rec" (sad it ended already), "Rick and Morty", "Star Wars Rebels", "Game of Thrones", "The Simpsons", "X-Files" (Classic), Stranger Things (EPIC), and The Umbrella Academy (Season 2 was just WOW!!!).  My favorites Bands are The Cure, Postal Service, Modest Mouse, Weezer, Cat Power, The Shins, Explosions in the Sky, Death Cab for Cutie, Stars, and all things 80's...just to name a few.

Coming back this Year is "Evolving with Mr. V Podcast"...A weekly podcast that covers the week that was in AP/DC Biology and Much More...Give it a Listen on any Podcast Listening Platform.
