Sandy Spinrad is really excited to be at Lake Washington Tech! After nearly 10 years of part time computer science teaching working with students from first grade all the way through professionals at Bellevue College, last year Sandy took “the plunge” and have became a full time educator. He’s now teaching computer science at both Hazen High School in Renton and at Lake Washington Tech.
Decades ago, someone volunteered to lead a 4-H computer programming group in Sandy’s small town of Santa Ynez, CA, and introduced him to BASIC on an Apple II computer at the area’s one local computer store. Since that moment Sandy got hooked. He begged my parents to get him a Commodore 64 and with that, taught himself BASIC and 6502 Assembly language. This young love for computers blossomed into getting a BS and MS of computer science at UC Santa Barbara, and a very successful 28 year career as a Lead Principal Software Engineer at Microsoft, where he primarily worked on a variety of lower level Windows components.

Dave Dion was previously a chef running his own catering company. In the late 90’s when the internet started to bloom Dion taught himself to design websites, so he could create one for his catering company. When a friend heard that he knew HTML, Dion asked to join him in his internet company which was growing rapidly at that time. He decided to take a chance and change careers. He enrolled in Lake Washington Institute of Technology (then Lake Washington Technical College) to extend his knowledge of the internet and design software. During his time as a student, he was asked to teach an Illustrator course and continues to do so 18 years later.
In addition to his teaching, Dion does freelance design and consulting and works for a small private school as IT/web manager. When not on a computer, he prefers to be in the woods, on the water, gardening and/or spending time with his family.
