Tommy Joyner founded MilkBoy in 1994 as a rough-and-tumble punk and hip-hop recording studio in North Philadelphia. Over the last 20 years the MilkBoy brand has grown to include the MilkBoy venue, film production company BBCG Films, and SHAKE Audio Post. Today as head of MilkBoy the Studio’s engineers, Joyner is responsible for production on over 100 records and demos each year, numerous composition jobs for film and television, and he continues to perform as a drummer and side-musician both live and in the studio. Joyner has played drums in Digable Planets and overseen recordings by James Taylor, Dave Matthews, Meek Mill and Miley Cyrus. In 2014 Tommy produced the feature film “Slow Learners” with co-producers Tammy Tiehel-Stedman, Jamie Lokoff, and Brian O’Connor.

Cody Cichowski is an engineer, producer, and composer at MilkBoy the Studio, where he has been a core part of the team since starting as an intern in 2003. Over the years, he has grown into a senior engineer known for his work in music production, sound design, and film audio post. 
A multi-instrumentalist with a deep technical skillset, Cody specializes in surround mixing, SFX creation, and crafting immersive sonic environments.

One of Milkboy's longest-tenured engineers, Matthew has been part of the studio since 2015 — growing from intern to one of its most trusted voices in the room. He has worked alongside legendary string arranger and producer Larry Gold, contributing to records for artists like Bruno Mars, Tate McRae, John Legend, and Lil Uzi Vert, among many others.

With thousands of sessions under his belt, Matthew brings major-market experience to every project — the same level of craft and intention you'd find at the top studios in Los Angeles, New York, or Nashville, right here in Philadelphia. But beyond the records, what drives him is something larger: building a music culture in Philadelphia that artists don't feel they have to leave to be taken seriously. Whatever the project, you'll find a collaborator who takes your music as seriously as you do.

Sam Rosen started at MilkBoy in 2015 and has since involved herself in a wide range of recording and mixing projects. Although specializing in vocal mixing and production, Sam began as a songwriter and has a passion for working with artists to develop their projects and their sound from start to finish. Sam also produces/sings/and plays in her own projects Lucky Rabbit and samryebread. Some of her released work can be found on her website: www.samryebread.com

Owen Hatton has been apart of the MilkBoy team since 2022.  Moved up to Engineer in 2025, Owen has proved he's not just a Producer but a very capable Recording Engineer as well. Specialising in Trap Production, Owen has worked with rappers all throughout the Philly scene, contributing to the Philly sound with tracks like Kurt Angel by Skrilla.  

Jeff graduated from Temple University with a degree in TV/Film media, and landed his first industry job running the school's film sound mixing studio. Jeff is one of the original studio crew dating back to 1996, and his production credits span various musical genres (R&B, Rap, Gospel, Jazz, Classical, Rock) and industries, including theatrical sound design, radio commercials, video and film audio post-production, studio design and tech maintenance.
Jeff recorded and mixed most of Schooly D's first EP, which some credit as the first real gansta rap record, and has fond memories of working with such notables as Patti Labelle, Teddy Pendergrass, Justin Timberlake, Sigourney Weaver, Eddie Murphy, Gerald Lavert, Michael and Kevin Bacon, the Philadelphia Mummers, Bedouin Soundclash, Kid Cudi, Cool C, and Pepe the King Prawn (of Muppet fame).
Although not an In-House engineer, he's always Larry Gold's first call for all his string recording sessions.
