Expertise in FEA

Hi everyone. I graduated in mechanical engineering 6 years ago. I’ve been working as a designer engineer in manufacturing ever since. I’ve discovered quite an interest in FEA lately and I would love to get the expertise. My issue is that I can’t find good in school training for that and I can’t get employment in the field with the amount of experience I have. So please tell me, how did you guys get your expertise? I’m in Montreal so if someone could guide me to get where I want to be, I would appreciate it very much. Thank you
