Our Founder, Veronica Medina
Veronica Veras Medina, graduated from Catherine Hinds Institute of Aesthetics in 1997 and worked her magic throughout Wellesley, Newton, Chestnut Hill and Dedham for over 25 years.
Veronica was a talented and knowledgable aesthetician but her greatest gift was loving and pampering others. Just to be in her presence made you feel safe, celebrated and loved. After a long battle with cancer, Veronica passed away in January 2026. Every thing we do at Essential is focused on continuing on this important legacy.
