I’m Dan Dimitriu

Dan was born in Bucharest, Romania. After defecting to the refugee camp in Traiskirchen, Austria, Dan arrived in the United States in 1982. One month after his arrival, Dan started teaching engineering as a lecturer at North Dakota State University in Fargo, North Dakota. 1989, Dan returned to NDSU to finish his Ph. D. degree in engineering, graduating in 1993. That year, Dan came to San Antonio to work as a senior design engineer for Kinetic Concepts, Inc., a medical equipment company. In 2001, Dan decided that it was time for a career change, and he became the Engineering Program Coordinator at San Antonio College. During his tenure there, among other accomplishments, he received the 2015 Presidential Award for Excellence in Science, Math, and Engineering Mentoring and published two books to help readers improve their spatial visualization skills. As for hobbies, Dan enjoys traveling, movies, reading, and creating challenging educational materials such as books and games.
