Born in Barcelona in 1973, Mireia Serra aimed to be a sculptor from a young age, but her parents persuaded her to study fashion design instead. In 1995 she graduated with a degree in fashion design and started her professional career as a lingerie designer. In 1998 she left her well-paying job because she wanted to expand her creative talent and find happiness in the fine arts arena. Serra graduated in 2002 from the Llotja School of Arts in Barcelona (the same school that took under its wing Antoni Gaudí, Pablo Picasso, and Joan Miró), specializing in iron and bronze. Later she took an advanced sculpture portrait course taught by sculptor Jorge Egea at Museo European d'Art Modern in order to master her technique.

Serra has been working as a full-time sculptor since 2003. In some of her recent sculptures, the presence of elements from the fashion world such as cameras, texture, detailed finishing of the clothes and shoes make an appearance. She started to exhibit with galleries throughout Spain and landed her first solo shows and her first international art fair in Madrid in 2013. Since 2016, Mireia Serra has been exhibited in galleries and art fairs in Germany, Austria, France, Luxembourg, Sweden, Belgium, Italy, the United States, and Hong Kong. Notable collectors include Kelly Clarkson.
