Colin Kirkland

As someone who had taken years off singing, I was hesitant about jumping back in and lacked confidence in my voice. I started working with Monica to knock the rust off and see what I could be capable of with focused instruction. In just a few months, I was shocked to hear how much my voice had strengthened and opened up. Now, nearly a year in, my voice is light years ahead of where we began. Monica has an excellent ability to meet vocalists where they are and to build them up in way that’s knowledgeable, approachable, and fun. Whether a beginner or seasoned pro, I couldn’t recommend her more!
Michelle Lucas

All my life, I have been singing with tension and poor technique. Until I met Monica Sadler. Over the past year, she has patiently worked with me to identify, dismantle, and rebuild my singing habits and mindset. Monica pinpoints what I’m doing incorrectly, and then provides specific exercises and uses creative visuals to help me develop the technique to be able to sound better and sing with more confidence.
Ellie Grizzell

Oh my goodness, Monica! She is the best! Monica will guide you through a lesson with kindness while also helping you get to where you need to go. She loves challenging you and finding those breakthrough moments! If you need help in the studio or would like to start taking lessons, Monica is your girl. She will create a special and specific plan for you and your voice type. She will also make you laugh and feel super comfortable with sharing your voice! She is an absolute joy to be around and I’m so lucky to know her!
Lauren Elizabeth

Monica is such an incredible vocal coach. Every time I have a lesson with her I hear growth in my voice and am left feeling encouraged. Not only that, but when I am struggling with an exercise, Monica always creatively finds a way to help me accomplish the desired goal.
Lauren Evans

Monica has a great teaching disposition and immediately puts you at ease with her genuine manner. I valued how much I learnt from her in such a short space of time and was able to ask questions along the way. She has so much knowledge to share, makes it easy to understand and is really encouraging. She gave me some really helpful exercises to understand my voice more to gain control and relieve tension. Thank you so much!

Specilizing in…

I could never be a Vocal Coach…

I told myself. There are too many struggles in my own voice, how could I teach someone else to find freedom if I couldn’t even live it out myself. I loved music and knew I was meant to do something with the gifts I was given, yet everything I tried didn’t pan out like I hoped. I was ready to throw in the towel, until a conversation changed everything.
