TN holder residing in MI x 7 yrs want to switch to greencard

Hi there.
I'm a canadian citizen-TN holder, working as a pharmacist for the same company, and living in michigan, for 7 consecutive years. I am interested in changing to a green card to give me more freedom in where i can work. Is there a process in which i can apply for this without going through my company?
Thank you very much.
Sincerely
P. Crozier
