Dr. Warren was my voice teacher for quite a few years. I drove 3 hours round-trip for each lesson and always felt like it was well worth the time and effort: Yes, he's that good!
I cycled through three other voice teachers before finding Dr. Warren, each of whom either did not recognize or else cultivated incorrect technique so that I became frustrated and uncomfortable, with a very limited vocal range. Dr. Warren was immediately able to identify what to address first, and gradually helped to unravel the maze of confusion and bad habits that I had developed.
He is encouraging, supportive, friendly, and a master teacher, with an approach that always feels safe, at the same time making one eager to practice and improve more. Under his guidance, I learned to love the sound of my voice, singing became satisfying and fun, and I was able to handle music that I had never imagined I would ever be able to sing. I can't recommend him enough!
