Hi @ec - Thanks for reaching out!
We did a bit of research and it seems like there are a lot more fly fishing classes available than spin/bait fishing. Depending on what style you are interested in learning, the following organizations might be a good fit:
- JB Fly Fishing Lessons
- Phoenix Fishing Supply - their Facebook page mentions offering classes; sell both fly and spin/bait supplies
- Arizona Game and Fish Department - offered a Sport Fishing Education Program in the past, but you will need to contact them at (623) 236-7240 for current offerings
Hopefully this helps!
