Superior Vocal Health is the result of more than 20 years of research and investigation by David Aaron Katz, Cantor, international singer of Opera and Broadway, voice teacher, coach, author, nutritional consultant, herbalist and lecturer. While working with, teaching and coaching actors, singers, lawyers, clergy, and professional speakers from around the world, David found that all voice professionals were in constant need of something that would help preserve and take care of their voice that was not addicting or damaging to the cords, and that was consistent, safe and reliable. In addition these voice professionals were much more trusting and felt more secure about using Superior Vocal Health products to maintain their voice and throat knowing they were natural and organic certified.
