Artist Statement

As someone that grew up with YouTube, I love being able to work in the space, and hope to expand to other social media as well. I would love to work in all sorts of fields, such as Podcasts and editing for TV someday. For right now, I want to continue to edit for YouTube and Vertical creators, and perhaps start working on my own content. 


From a young age, I’ve always been drawn to media. I believe film, television, and photography are such beautiful and powerful works of art and communication, and I’m truly honored to be able to play a part in it. I really like the idea of taking anything and transforming it into a new piece of art: whether it be a project started from scratch or simply changing a few things to enhance the overall project.

I want to be known for making people laugh. I work to create new stories through my edits and strive to constantly grow and learn new ways to make meaningful and beautiful stories regardless of what my position is in the process.
