Mariana has been making art since she was three years old and her mother gave her tempera paints and brushes; her parents gave her a childhood rich in art, music and dance. She majored in Flute Performance in college and spent the first 30 years of her adult life working as a professional classical and jazz musician and teaching flute and piano.

She now works full time out of her studio in the home that she shares with her husband, John Kramer, in the Atlanta area. She works in mixed media: painting in watercolor and acrylic, making collage, floorcloths and sewn items. She also teaches beginning sewing lessons.

She and John lived in Cuernavaca, Mexico, for several years, and still have a home Mariana designed in the village of Ahuatenco, Estado de Mexico, Mexico. Mariana has travelled in Europe, Canada and Latin America and her work sometimes reflects her travels and her love of Hispanic culture. She tutors students learning Spanish.
