tammie leung   director · marketing & graphic design

Native from Hong Kong but left her home country and went aboard since 16 years old. From Vancouver to Shanghai, she first completed her bachelor degree with a major in business administration. In a week before her graduation ceremony, she volunteered to help the board to design a graduation leaflet without any art or design background. Surprisingly, this experience seeded her passion in design. She decided to travel to San Francisco, a wonderful, international city to seek her path in design. She stayed in San Francisco and completed her second bachelor degree majoring in Graphic Design at the Academy of Art University. As proud as she could be, she told herself, “This is just the beginning of my design journey.”

Combining with her business instinct and the experience of being a freelancer of graphic design, she strongly believes that a successful business is only possible with good marketing, branding and visual design that sync well to present the company’s story and values. She also realizes that under the technology influences, new media is the bridge to connect between audiences. Print design is no longer the dominant source to communicate; interactive design on screen can speak louder and more effectively. Bracing with this believe, she starts working as a visual designer and continues her master degree in New Media and Web Design at the Academy of Art University.

Designing for print and for screen are similar but different. Both are visual communication, but the visual aspects are different. Taking advantage of her prior aesthetic in graphic design, she is able to unlock her creative vision and design potential in the field of new media design.
