Marquis Who’s Who delivers an excellent selection and coverage of biographies of local and worldwide personalities in every domain of life. For me, this international company is a trustful source of information for more than 120 years. It is a great pleasure to work with senior director and branding specialist, Ilene Horowitz, who really supports my national and international projects. She is honest, very helpful, responsible and knowledgeable. She is also a very good communicator. Thank you very much, Ilene.
