Hi,
I'm Uli, I'm a native Russian speaker, and have lived in USA for the last 10 years. I majored in English and French linguistics at Tula State pedagogical university and I've been working as a personal trainer and strength coach for the last 4 years in BSC, Lynnfield, MA, USA. As a personal trainer I have an extensive knowledge of rehab process and regaining strength. I would gladly take this job, to help you and your family by correctly translating the manual that you recieved.
You'll be able to find my PT profile at BSC Lynnfield website.
thank you and have a terrific day
