Linda Dobbs
Instructor
Linda Dobbs
Instructor
Linda should have been born in Texas, but the USAF decided she would be born in Arizona. She did eventually make her way to Texas, attending high school in San Antonio and then receiving B.A. degrees in English, Computer Science, and Mathematical Sciences from Rice University.
After a stint with IBM in Austin, Linda began pursuing her greatest passion – offspring. She and her husband (Bill) created three amazing human beings. These three amazing human beings then created Linda’s passion for teaching, and Linda and Bill decided to homeschool their offspring. Homeschooling led to teaching at the Austin Area Homeschool Cooperative which led, over time, to teaching here at ATA College Prep. Linda enjoys teaching mathematics, literature, grammar, theater, and history. She believes in the Oxford comma.
Although Linda has little innate athletic talent, she does enjoy lifting weights and punching bags with her little, red boxing gloves. Her offspring obviously inherited some recessive genes, and all became college varsity athletes – the girls both in crew and the boy in tennis (after some time here at ATA) – giving Linda some solid second-hand understanding of the athletic mind.
Linda also enjoys reading (my first love), cooking (and the corollary eating), and drama (both in and out of the theater). She is currently on the board of the Lakeway Players and directs a show about once a year.
Linda is not prone to philosophizing, believing that Coach Tommy has that sewn up, but if she did have a philosophy of teaching it would be:
1) The most valuable thing you can learn is how to teach yourself.
2) The most valuable thing you can teach is how to work.
Simple, but not easy.

Jon Watson
Instructor
Jon Watson
Instructor
Jon joined the ATA College Prep team in the fall of 2023 and has enjoyed teaching Math & Logic 1 and 2, Creative Thinking, Debate, Physical Science, and Shakespeare Thru Performance (his favorite!!). After receiving his BS in Communications from the University of Texas in the early 1990’s, he earned an English Teaching certification from UT four years later.
Jon began combining his passion for theatre and his love of language arts in 2001, when he began working with homeschooled students via Zachary Scott Theatre’s Performing Arts School. Hearing young people share their own creative ideas while staging A Midsummer Night’s Dream or encouraging them as they wrote their own original music for an adaptation of the classic Greek comedy Lysistrata brought him immense joy. After six years as the Assistant Director of the school, Jon wanted a change — and he got it, teaching English abroad in Taiwan for over a year and enjoying travels to Thailand and the Philippines as well.
After returning to the US, Jon taught both Speech and sophomore English at Westlake High School, sponsoring both the Debate team and the Model United Nations club in their travels to Chicago, Kansas City, Duke University, and elsewhere. Six years later, Jon left Westlake to become the elementary and middle school Theatre teacher at Austin Discovery School in east Austin, where he remained for seven years.
Jon is the proud bio dad of three super-creative kiddos — as well as the loving cat dad of rescue kitty Lily. He enjoys solving the New York Times crossword, writing music for the songs of Shakespeare, visiting with his twelve nieces and nephews, playing Scrabble, and making homemade ice cream (you should try his miso salted caramel). When it comes to his teaching philosophy, he borrows from Walt Whitman, encouraging students to “rivet and publish” their own personalities through hard work, dedication, and risk-taking. He looks forward to lotsa learning and playing in the year ahead!
