Toni’s journey into aesthetics began years ago while working in marketing for a well-known beauty and med spa brand. Immersed in that world daily, she developed a strong desire to be more hands-on with patients and help them achieve real, transformative results.

She followed her passion by enrolling in aesthetic school, where she gained expertise in treatments like Morpheus8, microneedling, HydraFacials, and more. After graduating, she joined another med spa and quickly fell in love with helping clients feel confident.

Driven to grow further, Toni made the decision to attend nursing school - a rigorous two-year journey filled with late nights, dedication, and a commitment to deepening her medical knowledge.

Now a licensed Registered Nurse, Toni is a part of the team at A Renewed You.
