“Katie Osness taught me throughout my musical theatre degree at WAAPA, and I could not recommend her enough. Her professional technical knowledge of vocal physiology, singing styles, vocal health & vocal technique is of the highest calibre and quality out there. But it is her teaching style that truly makes her a standout and the best in the biz! Katie provides a safe, warm environment for her students with a zero judgement policy, and teaches with support, kindness and compassion. She encourages growth by lifting up her students as individuals and she works with you and your unique voice to find what techniques, repertoire and vocal choices work for you. She worked with me and my voice in every lesson, tailoring my warm-ups, cool-downs and everything in between. I felt safe to try new things, go outside my comfort zone and really explore my voice with Katie’s support. She truly helped me find the confidence and passion to be myself and be proud of my voice. I couldn’t be more lucky to have had Katie train me in my most formative time as I trained to be vocally fit for the musical theatre industry, and now as a professional musical theatre performer in my first major musical contract, I can confidently say that Katie has set me up with the tools I need to thrive.
