Katherine Castro has been perfecting her craft in the nail industry for 11 years. Licensed in Connecticut, where she completed her foundational education and training, Katherine has spent the last three years deepening her expertise through specialized certifications and advanced coursework — a reflection of her belief that great work requires continuous growth.

 

Her strengths lie in attention to detail, genuine client care, and creating healthy, long-lasting nails. She is passionate about educating her clients on nail health, ensuring that every set she creates is as strong and lasting as it is beautiful. Her signature service is the Russian manicure combined with structured gel — a precise, meticulous process she loves for the clean, polished finish it delivers and the durability it provides.

 

For Katherine, the heart of her work has always been the client experience. She takes pride in building real relationships, creating a space where clients feel comfortable, cared for, and confident when they leave her chair. Those who know her best would say she's caring, detail-oriented, and easy to talk to — someone who genuinely wants the best for every person who sits down with her.

 

Katherine chose Obsidian because from the moment she walked in, it felt like home. The welcoming atmosphere, the sense of community, and the opportunity to grow alongside talented professionals in a beautiful environment made it the natural place to plant her roots.

 

Outside the salon, Katherine is a proud mom of three children, all under the age of four. She finds joy in making memories with her family, exploring new places, and striking the balance between a career she loves and the people who matter most to her.
