Tim Castle
Tim Castle has over 30 years of experience supporting computers, including 14 years working in Information Technology departments in the Silicon Valley. Tim started tinkering with computers a little in high school, and quickly discovered a knack for problem-solving and a penchant for achieving business results. Tim has experience working at startups from height of the “dot-com” boom. There, he learned how to move quickly, work independently, and wear a lot of different hats. Since then, he has worked supporting business needs in a wide variety of start-up and SMB environments. Tim has been doing independent consulting since 2002, and have found out how grateful people can be for someone who will show up on time, listen well, and treat them with respect. He hopes you can expect the same from working with him. Mr. Castle holds a Bachelor's Degree in Mathematics & Computer Science from Pepperdine University.

Joshua Fleitell
Josh has been taking things apart since he was a little kid. Not much has changed, except now he (mostly) puts them back together again. For Sentant, this often means constructing audio-visual equipment and server racks, as well as integrating A/V and corporate systems. Joshua is proficient at multimedia coding such as Arduino and MaxMSP, A/V suites such as Touch Designer, as well as shell scripting and systems integration. While not pushing buttons for other artists and designers, he can usually be found in the dark doing strange things with electricity; creating the things that go blink in the night. His work as a creative engineer and programmer can be seen in a variety of venues across the world, with clients ranging from Blue Man Group to the Empire State Building. He has served as technical director for the band OKGo, where he was responsible for ensuring visually-rich performances went smoothly on tour for this popular act. If you're ever been in New York City and seen the lighting on the Empire State Building or the Kosciuszko bridge, you've seen Joshua's work first hand. Joshua holds a Bachelor of Fine Arts degree from the California Institute of the Arts and worked for industry-leading multimedia firm WorldStage (formerly Scharff Weisberg) before transitioning to consulting work. https://www.linkedin.com/in/joshua-fleitell-4698676/
