Since 1999, my medical and surgical practice has been limited to voice care. I maintain an

informational web site on voice disorders - voicedoctor.net, preceptor medical students in their

early years at Oregon Health Sciences University, offer an international fellowship in laryngology as

well as short observerships to physicians, speech therapists, voice teachers and interested students.

I produce “voxdoc, the voicedoctor” on YouTube, including Laryngology 101, a series of learning

videos. I published “Why is there a frog in my throat? A guide to hoarseness.” I frequently lecture

internationally on laryngology and phonosurgery. I remain surprised at how much there is still to learn

about the larynx.
