Christy is an awesome accountant and adviser. I highly recommend her for personal tax and business tax. Not only she help with our taxes, she even organize our entire book keeping for very reasonable price.

Running a small business is an extremely challenging task. However with a team like FAS, I do not have to worry about our bookkeeping and tax services. Cristy and Dennis have been a vital piece to our company. I am glad that we can count on their timely response, budgeting plans and cash flow forecasting to help us financially prepare for business objectives.They are truly great team! More...

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. Since I hired FAS Bookkeeping & Tax Services, I have peace of mind knowing that my financial records are maintained correctly and updated monthly. Using QuickBooks online as our accounting system, instead of QuickBooks Desktop maintained at the CPA firm office and to which we don’t have real-time access, now, we can run reports customized to our needs and we can generate reports when we need it. If we need to consult with FAS, Cristy Fontanilla, is always willing to schedule a time to meet with us and answer questions we have. At tax time, I know that I will be stress-free knowing that my company is taken care of by FAS who truly cares about the success of their clients. They were very attentive to our questions and very patient in explaining situations to us which we really appreciated.I highly recommend FAS to business owners who are looking for a reliable and professional bookkeeping and tax preparation service firm.

VERY RESPONSIVE!!!!!!!FAS bookkeeping service has been an integral part of my consulting business. For many years now, I have peace of mind knowing that my financials are in order. If we have questions about our business financials and need help navigating through the complexities of our QuickBooks accounting system, Cristy Fontanilla, willingly finds time to meet with us to answer questions we have or provide us guidance. This really means a lot to us as business owner. FAS exemplify the true meaning of outstanding client service. I highly recommend FAS to business owners who are looking for a reliable business partner to handle their bookkeeping needs. More...

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.

FAS, with Cristy & Dennis, has been an important part of our progress as a company and I will not hesitate recommending them to business owners who are looking for a serious business partner for such a sensitive financial matter.

“Being a small business owner means we’re always constrained by time and resource. There are so many bookkeepers out there but finding the one with the right expertise and passion to help their client succeed, is hard to find. I highly recommend FAS for your bookkeeping and tax preparation needs”. More...

Fontanilla Accounting Services is the best accounting services 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 services.Marv ConwayTIGER-ROCK Martial Arts More...
