“Professionalism and integrity…”

My company has been an Eder Casella & Co. client going on two decades. Our company was founded and managed by a CPA with many years for Public Accounting experience; so we understand the criteria used to evaluate the professional services of a CPA firm. Without hesitation we can attest to the professionalism and integrity of Eder Casella & Co. and would recommend their services.

“Personal attention…”

The best part about working with Eder, Casella & Co. is the personal attention they have given our company over the years. They work with me to get our payroll done efficiently , which takes away a lot of stress knowing that it is done correctly. When setting up our accounting software, they guided me through the process to establish our reporting in a format that works best for us. Everyone I have worked with is ready to answer any question very quickly, and they always make sure that we are happy with the services they provide our company.
