Brow Artist

Kristina studied at the college of international esthetics and received her esthetician license in 2019. Her beauty journey started 9 years ago as a makeup artist at Sephora. She has always had an eye for brows and plans on getting certified as a PMU artist. 

She was born in Slovakia and raised here in Colorado. In her free time, she enjoys spending time with her family, biking, and taking trips to the mountains. It brings her joy when she can make someone feel confident and beautiful in their own skin. 

She has always been about brows and is so excited to start this new journey as a brow artist here at Highbrow.
