MANAGEMENT TEAM
Vanya Zlateva- Executive Director
Vanya fell in love with BEST’s mission as soon as she attended one of our competitions. With a master’s degree focused on Marketing and Business planning, as well as over 13 years of professional experience in various fields – media, e-commerce, digital marketing, sales, she wanted to apply her skills and knowledge in a way that would support Bulgarian youth. Vanya is a very results-driven and her self-starter personality has helped her launch and expand a number of different companies – magazines, an online store, a digital agency, etc. Her international experience has taught her the importance of foreign language skills, as well as critical thinking, public speaking and self-initiative and she sees BEST as a place where she can help young people foster that through the power of speech and debate. When she’s not dealing with the numerous responsibilities she has when it comes to running our community, she enjoys reading, yoga and swimming.
