I have met many more trainers that are top quality in my book that don't have any certifications under their belt than trainers that do. I find that people use the certifications to "prove" what they know about dog training. The proof, in my opinion, is in how many titles in obedience and or schutzhund the handler has on dogs, client referrals, and how he/she handles my dog in front of me on the fly. If they can't handle him/her or can't show me what they can do for me, or can't show me a dog they are working with or one of their own...I would never consider them a trainer.....no matter the certifications. Just my 2 cents.
