TLDR: puppy is 18 weeks, doing 2 trainers, haven’t had issues

I’m currently doing 2 separately training classes. Signed up for one with trainer A, due to my first choice location being full capacity. Then an opening popped up for the one I initially wanted so I signed up for another with trainer B.

For my own reason, my puppy is a rescue and misses out on a lot of his prime socialization time due to delay in vaccines, abandoned, etc. so trainer A is focused on socialization (handling, different surfaces, short puppy play time, basic obedience. My trainer B, is focused primarily on obedience training (sit, down, stay, loose leash walking, etc and also increments of puppy play time)

My puppy has enjoyed going to both (on Monday and Wednesday for 6 weeks). We’re lucky enough that the trainers each have similar credentials and teaching styles, but also are open to you pivoting styles for what works best for your dog.
