We are proud of our track record.

Mainstream Source President, Tad Sisler, and staff of professional filmmakers, producers, composers and editors have been awarded multiple film festival awards for our works.  We are grateful to have built lasting friendships with clients throughout the years.

Tad Sisler and I have worked together on several projects that required both extreme attention to technical specification and creative musicality. These types of projects require you be part computer programmer and part artist. Tad has the ability to combine the technical programmer part with the creative musician part and end up with a piece that satisfies all needs. I think Tad’s other great strength is his ability to shape and refine through collaboration. We’d often work on material together, bouncing ideas off of each other and Tad would always be able to incorporate ideas, offer alternatives and apply the finishing touches that elevate something from good to great.
