Our Story

From Humble Beginnings.

As an immigrant from Hong Kong, Mary Wong, EA, has come a long way. In her journey to get where she is today, she faced many obstacles, including language barriers and an unfamiliar culture. But through hard work and dedication, Ms. Wong was able to complete college and eventually start her own business.
She has always had a heart for helping small businesses succeed as well as investing in her local communities with her extensive professional knowledge. Now, as the incumbent president of the board of directors of the Asian Youth Center, she is helping to raise awareness of how AYC/Project NEO can help our children who face academic challenges.

To Professional Success

Mary studied at Cal Poly Pomona’s School of Business Administration. Through a series of successful professional experiences, she started a successful accounting firm in 2007.

Aligning Her Life’s Passion To Her Professional Journey

In 2010, Ms. Wong founded Project NEO, a 501(c)3 non-profit organization that provides after-school tutoring and mentoring to at-risk youth in grades two through eight. During the academic year of 2015-2016, over 250 at-risk youth received individualized tutoring.

Over 200 young people were trained to provide tutoring services to youth in need of academic support. As part of its leadership development program, Project NEO initiated a Student Leaders Board, which consists of 12 bright individuals from local high schools and colleges.


In order to expand the outreach of Project NEO, Ms. Wong explored creative options. Asian Youth Center approached Ms. Wong to form a partnership that would pool resources to strengthen the tutoring program for children, a component of what the Asian Youth Center was looking for. Non-profit mergers are uncommon, but Mary always says, “Where there’s a will, there’s a way.” Finally, the two organizations merged in November 2016.
In addition to her non-profit organization and accounting firm, Exact Tax Inc. has served the local communities for over ten years. They launched free seminars last year to help attendees understand everything from navigating audits to filing taxes while awaiting a green card.

Trusted Community Leader

Mary’s outstanding leadership and relentless efforts in addressing the need for tutoring academically challenged children and providing tax seminars for the community are two of the many reasons people put their trust in her.
