One Source Process

is not just defined by its Founder and CEO, Brandon Yoshimura, but also by its accomplished partner, Danny Koo. With a wealth of experience in government contracting, business administration, and sales, Danny has made significant contributions to the company’s growth and success.

Hailing from Buenos Aires, Argentina, Danny’s multicultural background is a valuable asset. Fluent in both Spanish and Korean, he embarked on a journey that eventually led him to Salt Lake City, Utah, during his childhood. He pursued higher education at the University of Utah, where he earned a BA in Economics. His path eventually led him to Washington, DC, where he met his wife, Natalie, and together, they are the proud parents of their son, Oscar, and daughter, Riley.

Joining One Source Process in 2018, Danny has played a pivotal role in shaping the company’s trajectory and reinforcing its position as an industry leader. His dedication to collaboration and unwavering commitment to customer satisfaction have paved the way for securing numerous government contracts from both state and federal agencies. This success has further solidified One Source Process’s reputation as a dependable and trusted service provider.
