The Culture

We believe that life is too short to spend 40 hours per week of our lives dreading work. Because of this, Tatsumi and Partners tries to make every minute of everyday as enjoyable and fulfilling as possible. This includes creating an office work environment that nurtures camaraderie and friendships as well as a place of team-work and family. Toward these goals, we plan various events and activities that promote relationships and a sense of pride. Our culture also focuses on contributing to our professions as well as to the communities. Toward these goals, David Tatsumi has served on the State of California landscape architecture regulatory board and has represented California’s Board on a national level. The firm has also participated in numerous Career Days and various schools in the Southland.

Events and Activities

We plan activities and events which promote bonding and interaction among our team members. These may be specifically work related but also have absolutely nothing to do with work! Past company trips have included bowling tournaments, basketball games against other firms, trips to Las Vegas and even a cruise trip!


School Career Days

David Tatsumi, founder of Tatsumi and Partners, has participated in many Career Days at various schools around Southern California. Grades range from 3rd grade students to addressing students at California Polytechnic University, Pomona. A fun exercise for the 3rd graders was to take a blank sheet of paper and design what they would like to have in a park. Then they were asked place each item somewhere on the paper. This process made them think about what each item was and what their functional relationship with the other items were. They were quickly able to determine that relationships such as drinking fountains should be close to play structures because they’ll get thirsty by playing on them.
