I have known Christy for about 5 years. She has assisted several of my clients and me personally.

If you are a business owner, Christy makes an outstanding strategic partner. I highly recommend her.

I started looking for a new bookkeeping and tax service firm as my company was no longer getting the service and attention that we deserve from a CPA firm.

I highly recommend FAS to business owners who are looking for a reliable and professional bookkeeping and tax preparation service firm.

Because of the nature of my business and report requirements from corporate that are time-sensitive, I can count on Cristy and her team’s eye for detail and reliability to deliver accurate and timely financial information.

We've been with FAS for years and they are one of the most professional and honest people we've worked with.

I highly recommend Cristy, Dennis and FAS Bookkeeping & Tax Services Firm.

Being a small business owner means we’re always constrained by time and resource.
