Greene Lyon Group History  


We have decades of experience in business operations and management, and in successfully bringing a start-up to IPO in a short time frame.  

The idea for Greene Lyon came out of our electronics manufacturing experience, and we have pursued this idea relentlessly – and successfully – for the last 10 years.
