Testimonials

"In my 45 years running a finance department as a controller, treasurer and CFO I have never come across a firm like Grassi that provides such a high level of professionalism and technical services."

Paul R. on December 11, 2023

"When we searched for new auditors we wanted a firm with DDI industry expertise, with strong auditing procedures but reasonable to work with. The field team from Grassi quickly learned about our agency, provided prompt responses to questions, kept us apprised of the audit status and tailored their procedures to utilize our existing workflows. It was an excellent first-year audit and we look forward to our continued engagement."
