Introduction: I'm a CPA and have been in business for 20 years, started my career with KPMG (one of the Big 4 accounting firms) and held other management positions in local accounting firms in Newport Beach and Irvine. I started my own firm (Nexus Square) in 2009 to provide the same level of experience in accounting and tax offered by big accounting firms to small businesses and their owners.

I had my tax returns for 2020 completed. The return was done well, the team was timely and professional. Great experience will use again

We could not be more pleased. We interviewed five other CPA’s and found Mohamed’s service to be far better in terms of experience for our small business needs. Mohamed has done several hours of research for us already and not yet asked us for a single penny. The quality of his work is excellent and so, we’ve decided to move not only our small business but also our personal accounting over to him. We recommend him highly.
