BARE Investors has training on investing (http://bareinvestors.com) but unfortunately, we are based in Columbus, OH where all our training is held. Try meetup.com there will be groups on there in your area.
I just learned about this school. But might be out of my price range right now.
I would consider reading a few books on commercial real estate before paying for any classes or training.
I haven't use them, but REFM is pretty well respected: https://www.getrefm.com/
You may also find something at ULI that's worthwhile: https://uli.org/
I would also echo many of the comments above. Get a hold of a few good books before you spend too much money on courses. There's a ton of information available online across all asset classes.
