Silveira at a glance

Founded to work with the enterprise-building spirit, advising real estate investors, international, and business to grow to the next level of success.


Lets talk tax strategy.


Our tax-strategy focus, coupled with collaboration, is at the heart of what we do, which is to provide a seamless process for our advisory and compliance services and to help our clients mindfully form, build and evolve their enterprises.

We don’t do it all ourselves. We like to work shoulder-to-shoulder with our clients and all of their advisers – in fact we insist. The products are better and the work is more thorough.

We believe this approach provides a truly client-driven result.

Our goal is to be a CPA firm that our client WANT to talk to on a regular basis – even if just to chat.
