I'll just say that my business was started by the owner in his farm's shop rebuilding/selling motors. When he expanded to doing controls they were like 3 employees and his friend was the electrician who they hired on. Since then the Electrician partnered with his Son-in-law and they train the majority of their guys right from their apprenticeship.
As much as I keep using "My company" throughout these posts I'm still just a guy in a programming/integrator role.
