About

What do you think a "good accountant" does?  Most answers include nothing more than preparing necessary tax returns once a year and sending them to you for signature.  However, we want you to raise your expectations!

We are a unique Tucson, Arizona CPA firm that focuses on providing comprehensive accounting and tax services to meet the needs of small business owners by providing relevant advice on more than just tax issues. 

You and your small business need to make decisions more than once a year. Looking at the history of your business is nice, but how about planning for the future of your business? How about proactive advice and guidance along the way to help you make informed decisions?
