    I love what I do and it makes me so happy to be able to share my passion with others.

    In 2005 I found a voice teacher who taught a technique that changed and improved my voice in a way I never thought possible. I finally had the right tools to give my voice consistency and my performances greater confidence.

    With a love for teaching, I joined the Speech Level Singing Teacher Certification Program. After certifying to a Level 3 Instructor, I moved to The Institute for Vocal Advancement to continue my education and certified to a Level 5 Mentor Instructor.
