EOS History

EOS has been serving multinational companies since its formation in 1996. Our firm was established through the transfer of a segment of Ernst & Young’s Japanese business practice. This was done with the intent of bringing greater value to our clients by focusing on the needs of small-to-medium sized companies just starting operations in the U.S. as well as those companies who have been in the U.S. for a number of years. We believe that through our smaller structure, we are able to provide a hands-on approach to better tailor our services to meet the needs of our clients.

Originally based in Teaneck, New Jersey, we have recently relocated our headquarters to Hackensack, New Jersey to accommodate our growing company. In addition to serving as our headquarters, the New Jersey Office serves our East Coast clients. As we gained traction, we established our first Silicon Valley Office in 1999 in San Jose followed by the establishment of our Los Angeles (Torrance) Office in March 2003. In December of 2003, we opened our Honolulu Office and in October of 2006, added our second Silicon Valley Office in San Mateo. Together, the San Jose, Los Angeles, Honolulu, and San Jose Offices serve our West Coast clients. Our Detroit (Novi) Office opened its doors in February 2007 and our Chicago (Schaumburg) Office was established in June 2010 to serve our Mid-West area clients. In 2012, we opened our Tokyo Representative Office to liaison with the headquarters of our Japanese-owned clients, and placed a representative in Knoxville, Tennessee to serve our clients in the Southern part of the United States. In 2014, we opened out Houston office to serve our clients in Texas and surrounding areas.

In 1996, EOS began with three Partners and four employees. In the nearly 20 years since then, our business and size have expanded as well as our service capabilities. Today, there are 12 Partners and Principals and over 100 employees firm-wide. We look forward to the continued support of our clients as we approach our 20th anniversary.

Career
Born in Fujian, China. Began working at EOS in October 2009.
Hobby
Photography and running
Message
I was educated in China and received an MA in material sciences and engineering from the University of Science and Technology, Beijing. However, my real interest was in accounting because I am, by nature, analytical and good with numbers. Once in the United States, I chose accounting as my career and earned a Master’s of Science in Accounting. Within six months, I passed the CPA exam and found I had a real passion for the subject. I believe accounting is the common language for all businesses and that there are countless opportunities for people with accounting backgrounds. read more ...
