Delivering Quality Accounting Services for More Than Two Decades

PBTSI is an accounting firm in Las Vegas, Nevada, that offers advisory and consulting services for a vast pool of clients. If you’re looking for experienced and reliable public accountants to help you with your needs, you’ve come to the right place!

Outside-the-Box Approach to How We Work

Our company was founded on the idea that there is a better way to help clients with their accounting and tax challenges.

Upfront Client Interview and Engagement

We believe that selecting an accounting professional is a personal choice. The accountant you will choose, to properly do their job, will have a window into your finances.That’s why every client engagement starts with either an initial assessment of your business or individual financial situation to structure the right relationship in the future and ensure that we are the right fit for your needs.

Ongoing Assistance

Our client engagements are structured as ongoing or annual programs, not one-off transactions. This is because year-long contributions to our clients’ businesses can help them avoid the end-of-year panic most people associate with accounting.

Regular Contact

To ensure that we’re always up-to-speed on your situation, we require regular review meetings.

Our Mission, Vision, and Value Statement
