Systematic Approach to Voice

Kari Ragan, DMA, MM, BM, is an internationally recognized voice pedagogue and Singing Voice Rehabilitation Specialist (SVRS) with a career spanning more than four decades. She is known for her commitment to applying voice science in service of artistic expression—a guiding principle that has shaped her work with singers across genres and career stages. Dr. Ragan earned her Doctor of Musical Arts from the University of Washington (2005) and both a Master and Bachelor of Music in Vocal Performance from the Indiana University Jacobs School of Music. She received the Van L. Lawrence Fellowship in 2012, was named a Master Teacher for the NATS Intern Program in 2021, and was inducted into the American Academy of Teachers of Singing in 2025. From 2010 to 2021, she served on the voice faculty at the University of Washington and has maintained a vibrant independent voice studio since 1983. Working in affiliation with the University of Washington’s laryngology program, Dr. Ragan collaborates with a multidisciplinary voice team to support singers recovering from vocal injury or pathology and partners with voice clinics throughout the United States to help rehabilitate injured voices. An active presenter and educator, Dr. Ragan is frequently invited to give workshops and lectures for voice organizations and academic institutions nationally and internationally. She has presented for NATS, the Pan American Vocology Association (PAVA), The Voice Foundation, the International Congress of Voice Teachers (ICVT), and many others. Dr. Ragan is the co-founder and organizer of the multi-disciplinary Northwest Voice: The Art and Science of the Performing Voice Conference. Since 2011, she has also served as moderator of the popular NATS Chat series.
