Professional music producer/mastering engineer with over 20 years of experience. I've worked with a wide range of artists, from indie musicians to major label stars, and I'm passionate about helping you create the best possible sound for your project.

I will elevate your sound to new heights with a balanced blend of clarity, warmth, and cosmic depth.

My journey began with co-writing and producing tracks for my band, Breathing Theory. This experience opened doors to collaborate with producers like Malcolm Springer (Matchbox 20, Collective Soul) and Sahaj Ticotin (Starset, Nothing More). As I gained experience, more artists began reaching out, sparking a deep passion for producing and co-writing.

I bring feelings into the songs I sing and write, feelings I want my listeners to be able to reflect and reflect on. The songs I write is my version of being an open book. You get my songs? You get me.
