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.
