DAVID DICKEY has spent most of his adult life doing Japan-related training, consulting, and coaching, working with both Japanese and non-Japanese clients. Dave’s goal is to facilitate his clients’ discovery of ways for people to collaborate and thrive in Japan-U.S. and other mixed cultural environments. He believes that establishing understanding, relationships, and eventually friendships is the basis for personal and business success.

Dave graduated cum laude in Asian Studies (Japan focus) from Cornell University, where he began his study of Japanese in the intensive one-year FALCON (Full-year Asian Language Concentration) Program. Upon graduating, he honed his language skills by first working at a Japanese restaurant, then relocating to Japan and devoting eight years to the Tokyo Center for Language and Culture (TCLC). TCLC sent him to three regions in Japan: Tokyo, Kyushu, and Toyama. He became an Intensive Course Program Manager for TCLC, designing and conducting multi-week, live-in, intensive language and culture trainings for Japanese company employees working globally.

Upon relocating to San Francisco, Dave joined a Bay Area cross-cultural consulting firm and was put in charge of the Japanese language and culture training for Silicon Valley clients such as Intel and Applied Materials. Dave joined teams of trainers who conducted Working with Japan and Living and Working in Japan training programs for non-Japanese, and International Management Development programs for Japanese. Recently, in addition to his work with manufacturing and hi-tech firms, Dave has been working with pharmaceutical companies in Japan, the U.S., and Europe as they strive to improve their global collaboration and marketing.

Dave feels fortunate to be working with many of the same colleagues he encountered 25 years ago upon returning to San Francisco. His responsibilities now have expanded to include Working Globally, Leading Virtual Teams, and Teambuilding programs, although his focus remains on enabling Japanese and non-Japanese to live and work together effectively. Dave notes that, although in recent years more and more work with clients has become virtual, he still prefers to get together face-to-face, to build relationships, and to find paths to personal and professional effectiveness in the cross-cultural arena.

Dave lives in the San Francisco Bay Area where he and his wife participate in a wind and percussion ensemble, and where he enjoys riding his bicycle and photographing birds – “biking & birding” – every day.

KAY M. JONES has focused her career on facilitating communication and business among people from different cultures. She has lived and worked in China, Japan, France, the U.K., and the U.S. Through exposure to a variety of cultures and languages, Kay has honed her expertise and her ability to transfer practical wisdom to others.

Kay graduated cum laude from the State University of New York at Albany with a degree in Chinese studies and French language; subsequently, she completed graduate work in international management. She began her career at the Chicago Council on Foreign Relations, working in the areas of public relations and corporate fund-raising. Next, she spent three years working for Chindex in Beijing, where she coordinated sales activities for American and European manufacturers of hi-tech medical and scientific equipment. This involved frequent travel throughout the People's Republic of China as well as to Japan, Singapore, and the U.K.

Upon returning to the U.S., Kay began doing consulting work in diverse industries, including pharmaceuticals, consumer goods, law, heavy machinery manufacturing, and high technology. The cultures with which she has worked most closely are the People's Republic of China, Taiwan, Hong Kong, Japan, France, Israel, Singapore, India, and the U.K. Her work requires regular travel to these locations and other regions of the world.

In addition to conducting intercultural training and research for global corporations, Kay designs and adapts corporate training programs for specific global business environments. Examples include localizing and upgrading a workshop on organizational savvy for senior bankers in the Asia Pacific region; helping to create nine days of workshops in business skills for the Chinese employees of a global manufacturing company; and outlining dozens of modules of basic staff training for the hospitality industry in Saudi Arabia.

Kay speaks Mandarin, Japanese, and French as well as her native English. Her language skills led to her appointment in 2013 as the pronouncer for the annual South Asian Spelling Bee for northern California. She is co-author of Culture Shock! Beijing (Marshall Cavendish, 2008) as well as several articles on intercultural business topics. Twice each year, she guest lectures on global business issues at the University of San Francisco.

A resident of the San Francisco bay area but originally from a farm in upstate New York, Kay enjoys reading and listening to music (mostly the blues); she is also very active in feral cat rescue efforts in her local area.

*STEFAN MATTHIES is a trainer and executive coach who provides, in both the United States and Germany, personal and professional development in the areas of leadership, conflict management, effective communication, presentations, and team-building.

Born and raised in Germany, Stefan holds a bachelors degree in business administration and has studied applied cultural sciences at the University of Lueneburg. His first corporate position in Germany was in human resources at Babcock Textilmaschinen, after which he held marketing management positions at both RMM Marketing Research and at Springer&Lardon. As a management consultant and trainer at Fromm Management-Seminare, Stefan designed and conducted a variety of management coaching and training programs for German multinational corporations. Attending his programs over several years were executives and employees of Airbus, Allianz, Axel-Springer-Verlag, Beiersdorf, Bertelsmann, CSC Ploenzke, DaimlerChrysler, Gruner+Jahr, Hamburgische Landesbank, Nestlé, Philips, Premiere, RTL Television, Thyssen, and Volkswagen.

In 2001, Stefan relocated to Southern California and founded his own coaching and training firm there. In order to keep up with business developments in Europe as well as North America, he consults, coaches, and leads seminars in both Germany and the U.S. He has presented on cross-cultural issues at the Anderson Business School of the University of California, and on innovative leadership at the Microsoft’s Executive Briefing Center; in 2002, he spoke at the United Nations roundtable in Geneva. His personal client list includes, among others, Allianz, Avery Dennison, Bertelsmann, Ceradyne, Philips, SAP, and TimeWarner.

Stefan has been trained in global leadership systems, global executive coaching, cross-cultural training, transactional analysis for organizations, systemic neuro-linguistic programming, and the power of body language. He has enhanced his coaching skills by studying at the Newfield coaching and organizational learning program, and at the Wharton Business School’s executive coaching workshop. His interactive, results-oriented coaching and training approaches apply the personal development tool known as shadow coaching, plus Stefan’s own technique that incorporates humor, which draws on his training some years ago in the art of clowning. Stefan’s talent for humorously mirroring business situations has made it possible for previously defensive or otherwise reticent clients to become able to wholeheartedly seek innovative solutions to challenging business issues.

Although they visit Germany often, Stefan and his wife reside near the beaches of Southern California. Stefan is not only a trained clown but also a long-time actor, abilities that have proved useful in his personal life as well as in his professional services to corporations.
