Sierra Cornell

I’m a Los Angeles–based vocal coach and songwriter passionate about helping singers and writers reach their full potential. After graduating from Berklee College of Music, I’ve had the opportunity to collaborate with GRAMMY-winning and multi-platinum artists, writers, and producers, as well as release songs with numerous up-and-coming and established artists. These experiences have shaped me into a versatile and deeply invested creator.

As a voice coach, I combine my Berklee training with mentorship under celebrity vocal coach Adreana Gonzalez, a Master Vocal Coach of Speech Level Singing trained by the legendary Seth Riggs (coach to icons like Michael Jackson and Barbra Streisand). I’m also currently a teacher-in-training with the Institute for Vocal Advancement (IVA), further refining my understanding of healthy, efficient vocal technique. My approach blends artistry and science, using the most effective and up-to-date vocal practices to help singers transform their voices with confidence and ease.

Whether you’re here to refine your voice, grow as a songwriter, or reconnect with your artistry, I’d love to help you make music that feels true to who you are.
