What our clients are saying


FAS saved us from disaster.

I have been a client of FAS Bookkeeping & Tax Services for almost ten years now and became a client when my financial/accounting person left with no notice. Having never written a check, managed payroll, tracked…..all of the above and more. The idea of working remotely was something I’d not considered but I am so thankful I found FAS.

Their commitment to excellence and the attention they pay to the details of my business surpasses my previous experience and current expectations. I appreciate their financial expertise, professionalism and reliable service as they handle our business bookkeeping, pay bills and seriously make sure our business is tax compliant. (For the first time in the life of my business my taxes were filed on time). Cristy is just an email or phone call away and always ready to answer questions I have or provide assistance when needed.

I highly recommend FAS Bookkeeping & Tax Services.

FAS is the best accounting services (bookkeeping) I have encountered in my 39 years of self-employment. They are hard working, ethical and honest in every aspect of their professional lives. Both Dennis and Cristy have gone way beyond their normal duties to provide services at the highest level.

I highly recommend this company to anyone in need of accounting (bookkeeping) services.

With everything that you need to juggle as a small business owner, it’s so easy to get busy and take your eye off the ball. For business owners, starting with the right bookkeeping and tax service firm is key. We have been working with FAS since 2014. Cristy & Dennis are both reliable and with high work ethics. With FAS handling the bookkeeping, bills processing, cash flow forecasting and income tax preparation, I have peace of mind and can focus on growing my business while FAS handles the financials. I highly recommend FAS Bookkeeping & Tax Services, a company you can trust.

I hired FAS Bookkeeping and Tax Services to do my books since 2018; their Professionalism and attention to Detail makes me go with them.

They recently was going over our books and found that our Payroll Company took a large sum of money out of our business account since October of 2020. They notified me about this draft so I contacted the Payroll Company which have no good explanation for what they did and will therefore be losing my business here soon. They agreed to put the money back into our account ASAP

There is no way I would have been able to find this money if it wasn’t for Dennis and Cristy; I am so grateful to them.

For honesty and integrity, FAS should be the company you should talk to.
