Meet Kay!
Founder & Licensed Esthetician
My name is Kyungri Mason (aka Kay), founder of Nourish Skin Nashville, and a licensed esthetician. I'm native Korean and moved to US in 2012 for the love of my life, my husband! I graduated from Aveda Institute Nashville in March 2020 and started Nourish Skin Nashville in December the same year.
I started my career in one of those chain spas but after I saw their basic run of the mill facials they offer in less than an hour, I knew I wanted something more than that. I wanted to take enough time for each client to learn their skin, build my relationship with them, and offer 100% customized treatment for their skin needs. So I made my dream practice in my cozy little studio!
And since then I've been honored to be able to help all my clients' skin care journey and gain their trust. It's my joy to treat each and every one of you with love and truly care for you as a part of my dream. And I'm a constant learner and love diving into the latest studies in skincare so I can offer the right solutions and results for my clients. I'm looking forward to meeting you all!

Meet Roselyn!
Licensed Esthetician
Hi! My name is Roselyn Hernandez and I'm a Licensed Latina Aesthetician. I began my Esthetics journey in 2020 in the middle of a pandemic and I've thrived in this industry for 3 years now. I've fallen in love with being an Aesthetician.
While on this journey, I felt a strong calling to help/care for people through my passion for safe and effective skincare. As a person who struggled with acne and the effects taking a toll on my mental health, when I finally found healthy ways to manage it, I knew I wanted others to be able to have the same feeling!
But for me it's deeper than just the skin's surface. I want to help you love your skin at every phase, not only the "clear and textureless" skin that society and social media tell us to celebrate. I'm an advocate for self love and firmly believe that you "can't hate your skin into healing it." Let's start this journey together and loving it at every moment. I'm so excited to work with you at Nourish Skin Nashville!!

Meet Sasha!
Licensed Esthetician
Hi there, I'm Sasha, a licensed esthetician with a deep passion for transforming skin into its healthiest state. After making significant strides in my own skincare journey and gaining invaluable knowledge about our largest organ, I realized that skincare transcended habit; it had become a calling. This realization has allowed me to connect with my Korean heritage and discover essential rituals that keep me grounded.
In my sessions, I believe in creating a safe and supportive environment where everyone can explore their unique relationship with their skin. I am dedicated to educating and empowering you with practical, healthy skincare routines that can seamlessly fit into your daily life using my personalized, committed, and high-touch approach.
Outside of Nourish Skin Nashville, you will likely find me reading a book, visiting the Belcourt, or catching up on various television shows with my husband, Dan and our pets: Persimmon and Tony. You may also find me browsing local thrift shops, going to a local show, staying active with reformer pilates, and visiting the Nashville Zoo.

Meet Katie!
Licensed Esthetician
Hi, I'm Katie Wyllia! I'm a Tennessee native and licensed esthetician. After many years in the cosmetology industry, working as a hair stylist, I realized that I wasn't living out my passion. I knew I still wanted to love on people and help them feel beautiful and confident, but in a different way!
I spent quite some time searching and praying for a career that would fuel my desire for nurturing people. I was lead down the path of esthetics and I did a deep dive into the art of skincare and the industry as a whole. I knew this was something I wanted to be a part of! Before I knew it, I was back at the Aveda Institute learning to perfect my craft as an esthetician!
I believe skincare is not one-size-fits-all, which is why every treatment from me is customized with intention and care. Whether your goal is relaxation, correction, or maintenance, I'm here to support you every step of the way and create a positive, safe environment for you! I want to help you love the skin you're in and create a strong, trusting relationship with you! I'm so happy to be a part of Nourish Skin Nashville and I hope I can be a part of your skin Journey!
When I'm not at the spa, you can always find me at home watching Gilmore Girls while cuddling up with my dog, Harley, and my sweet husband, Billy. They are the joy of my life!
