Orchestration / Reduction

As an orchestrator, I love finding unique sounds and textures for each project to support and further the storytelling of both original and re-imagined work. I tend to take inspiration from the time period and world of the show as well as incorporate unusual instruments whenever possible (and appropriate).

I have orchestrated on over a dozen shows, both as a contributor and as a lead/sole orchestrator. From original work to straight reductions to complete re-imaginings, I love it all!

Music Direction

Both as a music director and assistant, I love getting to work with an ensemble over the course of the rehearsal process to find their unique take on the music. My studies and experience in all aspects of theatre have taught me how to communicate and collaborate well with the many other departments it takes to put on a show.

Being a theatre music director requires so many hats - from score preparation to vocals to logistics to instrumental knowledge and so many more. When working with the rest of the music team, I thrive when filling in the gaps where other collaborators may not be as comfortable, making sure the team as a whole is as strong as it can be!

Technology / Software

From Mainstage to Finale, from Abelton Live to Logic Pro, I am comfortable with a large variety of music software. I use Mainstage to program almost all of my shows and have created both performance and sweetener tracks.

My experience with computer science and IT support have made me an adept learner and troubleshooter, comfortable picking up new technologies and creatively attacking problems until they are vanquished!

Other Skills



I have studied musical theatre and jazz composition and have experience writing for small ensemble, big band, orchestra, and musical theatre.


As an elementary school student, I followed in my older brother's footsteps and started playing the horn. Ever since, I have played in wind ensembles, orchestras, worship teams, and, best of all, pits!

I am comfortable transposing and playing off of lead sheets.

Music Preparation

I prepare all of my own parts and scores in Finale. The cleaner it looks, the better it will be played!
