The heart of MAST is Mellow, Sofie and Tasha. We are longtime friends, and partners of thirteen years plus, who create all of our jewelry and leather goods in our individual Tucson studios. We bring our personal collections together to make up the foundation of MAST.

We work cooperatively to further curate what we hope is an  inspired and welcoming store with functional and mindfully made products.

Offering form and function in both the everyday staple and the modern heirloom feels right to us, and it is the standard that we set for ourselves as artists, as well as, for MAST as a whole.

The M in Mast

Mellow Dawn

Mellow is a radical, a lover, a fiercely compassionate human, a designer and a ever evolving leather crafter.  She meticulously works to create leather goods that will make you happy and are the epitome of both form and function.  Mellow loves to move and groove, grappa, her family (and yours) and making a bold and beautiful statement in everything she does!   The M in MAST.
