Jonathan Altfeld is an NLP trainer, communication coach, and founder of the Mastery InSight Institute. His official biography connects his NLP work to an earlier background in artificial intelligence and knowledge engineering and describes an approach centered on modeling how experts think, speak, and behave. It lists teaching areas including public speaking, communication, voice, belief systems, nonverbal communication, and NLP practitioner training. The provider's Finding Your Irresistible Voice page identifies Altfeld as the instructor and describes an audio program containing exercises on vocal mechanics, resonance, breathing, consonants, vowels, and tonality. These pages establish his authorship, training role, and course subjects. They do not independently validate NLP, hypnosis, influence, certification, student counts, communication outcomes, or claims about changing another person's trust or behavior.
PimpMyMind associates Altfeld with Finding Your Irresistible Voice and Flirtopia. His accepted provider page confirms his authorship and instruction for the voice program; Flirtopia remains a catalog relationship from the accepted research record. Neither entry establishes authorization, completeness, rights clearance, endorsement, or communication and influence results.
