“Casey explains why she feels the way she does in “Safer,” which showcases Matthews’ marvelous, strong vocals up and down the scales, stretching the passion and emotion in the piece with conviction.”

— Wisconsin Theater Spotlight, 2018

“As a dancer who’s not super comfortable singing, in only one lesson with Kiera I felt more comfortable being silly and loud than I have with any other voice teacher I’ve ever had. She’s so sweet and super professional, can’t rave enough about her”

— Amber W. from Thumbtack, May 2022

“Kiera Matthews has a bold, solid voice that holds its own against the volume of the pit band, all the while giving a snarky, darkly funny portrayal of a take-no-crap sex-worker.”

— Kassandra Novell

“Kiera is absolutely incredible! I’ve been in her studio for about 3 months and the progress I’ve made has been substantial. She is fun to work with, highly knowledgeable, and easily adaptable to my needs as a musician and singer. When I first started lessons, I had no formal training with singing, but in a short time we have been able to build my vocal technique more than I ever thought was even possible. I really can’t recommend her enough!”

— Connor H., student at New York University, May 2022

“Ragalie and Matthews accurately embodied two extremities of first date emotions, capturing their characters’ personalities perfectly. Ragalie appeared genuinely nervous, while Matthews delivered a balance of humor — fretting over ordering a salad — as well as somberness when sharing insecurities with her sister. Their voices blended together, even when their characters clashed.”

— Marquette Wire, 2018

“My newly-turned 16 year old son has been taking lessons with Kiera for about 3 months now and the difference is absolutely amazing. Not only has the quality of his voice improved, she's able to work with the voice changes that come with puberty, while still keeping the qualities of his voice that make it "his."

Even better, his confidence has absolutely skyrocketed! He is able to be playful with his facial expressions and movements because the singing part comes more naturally. He adores working with her and has learned so much!”

— Amy C. from TakeLessons, May 2022

“Kiera has been wonderful to work with so far in our two lessons together! I've previously taken 7+ years of vocal lessons and can say she really knows what she's talking about. She is personable, makes every concept and exercise very approachable, and really caters to my specific voice.”

— Elizabeth G. from Thumbtack, March 2023

“She approaches each lesson with fresh and contemporary pedagogies and ideologies that have continuously evolved throughout her career. Her range of experience and expertise has made her a wonderful fit for a variety of students and skill sets. She is an approachable, equitable, and experienced instructor whom I will continue to recommend to potential students.”

— Savanna M. from Thumbtack, January 2022

“Kiera is an absolute professional. She uses her extensive knowledge and education to assist in her teaching. Using a wide array of exercises and techniques, she helps harness your strengths, while also focusing on correcting your weaknesses. The end result is amazing productivity. I am much more comfortable singing than I was before I started my lessons with her, and I've discovered my natural range and have been working to increase my ability and my range. I'm completely satisfied with the results I'm getting.”

— Mike M. from TakeLessons, May 2022

“Kiera Matthews unloads a colorful voice as Gomez’s siren-wife, Morticia.”

— We Are Green Bay, 2019

“Kiera is the absolute best! She does an exquisite job when it comes to finding her students natural voices and allowing their individual beauty to shine through. I would recommend Kiera for any style of singing.”

— Joe M. from TakeLessons, May 2022
