I've been working with Nguyen & Co. on updating my financial business practices which used to be pretty 'old school'. My business used to do quite a bit of time consuming manual accounting, and they've been hugely beneficial to updating our practices, saving us both time & money. Most recently they have been instrumental in securing both my PPP & EIDL loans for my business. There were times during the pandemic when I was trying to secure the loans myself from a larger bank to no avail, and they provided me with advise which eventually led to success. I highly

As a new small business owner in the state of California, I found myself somewhat lost and intimidated with all the Tax laws and tax codes. I felt that the everyday changing tax laws would be impossible to navigate with out the right help and to still be able to run a business, but I am glad and blessed that I was referred to Nguyen & Co. They have helped me and my business for the past 4 years and guided me through the struggles successfully. Andrew, Gianna, Carlos and the entire team, have saved me from so many headaches and possible penalties by keeping my business running smoothly
