We'd like to provide you with an opportunity to get to know our staff as well as our firm's values before you come to see us. The following pages should give you an idea of what we're all about. We hope you enjoy them! Our firm provides outstanding service to our clients because of our dedication to the three underlying principles.
Whether you're an individual or a business owner, taxes are a fact of life, but when you work with an accounting firm like ours, our dedicated team of tax and accounting professionals makes sure that you have one less thing to worry about.

If you're looking for a cost-effective solution to managing your finances or feel like it's time you obtained an accurate picture of your financials so that you can make informed decisions about your financial future, we can help.QuickBooks is the ideal business accounting software for small to mid-sized business owners.
Every year, Congress promises to simplify the tax code, but every year, the tax code seems to become more complicated than ever. If you've tried tax preparation software and found it confusing, you're not alone. As the tax code becomes more complex, so does tax preparation software -- and you might not be getting all of the tax breaks you're entitled to.
The key to successful retirement planning is developing a plan that while based on your current financial situation, also meets your projected financial goals down the road. That's no easy task, however. Tax rules regarding retirement plans are complex. Each benefit plan has specific requirements as outlined by the IRS and it's important to understand the tax implications of your retirement planning choices.
Planning for your family's financial future is not just for the one percent; it's important for everyone especially if you have a spouse or children. The reality, of course, is that most people do procrastinate and never get around to estate planning until it is too late. There are many reasons why this happens.

Dean Brenner is a liar and a cheat. He will take all of your information and NEVER file taxes despite multiple correspondence stating otherwise. Do not work with him! I have reached out multiple times prior trying to get our paperwork back before posting this review. We have done business together for years with no issues however, clearly something has changed in his life and his moral compass has changed as well. We have called IRS and filed a complaint with the BBB and will not stop until this wrong is corrected.

I repeat DO NOT DO BUSINESS WITH DEAN BRENNER.
