I was lucky to be able to take film classes at Los Angeles City College. From there, I started volunteering with everyone who would have me, learning from awesome professionals and building up my skill set. A firm believer that while taking film classes is helpful, actually doing it is the only way to learn the skill.
I have worked professionally as colorist, camera, camera shader, DIT, lighting director/gaffer and producer. The main lesson that I've learned from working is that there is always someone who knows more than you do.
Stay curious. Stay humble. Work hard. If you do these three things, you'll always be busy.
