A British national...
... and a native Londoner, I've lived in New York (Long Island) since the mid-90's. I’m able to record your project in my own professional studio, or if required, I can easily travel to a designated studio in the New York metropolitan area.
For those who prefer live sessions, I offer full Source Connect connectivity as well as Skype, Zoom and phone patch connecivity. For customers in the US, I can supply your British voice needs whilst satisfying both legal residency and IRS requirements… and without those troublesome time zone issues.
I am happy to supply a test read to see if my voice fills your production's requirements.
