Welcome to Permies!!
We did a book giveaway last year with Leonid Sharashkin, Keeping Bees with a Smile He was awesome, posted quite a bit on the forums, and has classes he teaches. Put his name in the Search function here! Wonderful man, we loved him!
That book is an excellent place to start. It's geared towards very cold climates but it also helps understand things from the bee's perspective. Here's Leo's website https://horizontalhive.com/index.shtml which is also informative.
"Organic & natural" bee classes seem to be rare. I think Leo's would be excellent. Michael Cox runs a treatment free group on Facebook. Check his bees posts here at permies for that address. I suggest taking a beginner class from your local beekeeping organization & when they mention chemicals ask them about alternatives. Read some of the other permies bee threads too. The forum is not a class but it's natural & organic.
In my opinion & experience ... it boils down to starting with strong locally adapted bees in a nontoxic environment with plenty of bee food plants around. Then observe them carefully but mostly leave them alone. Survival of the fittest.
Argue for your limitations and they are yours forever.
