"We consider Grassi a valued partner, and they are much more like a member of our own team than an external services provider, working very closely with us and providing a great value to our team."

"Michele Holmes and Barbara Durante are fantastic! They get the job done in a responsive and timely manner. Grassi gives good tax and overall good business advice."

"The team at Grassi excels not only in technical expertise but also in collaboration. They have taken the time to understand our organization, working seamlessly with staff at all levels, and providing constructive insights that strengthen our financial processes. Their high-quality work has earned the respect of our team and our Board."

"Great staff and great process for yearend audit and tax services"

"The customized support and the genuine commitment to customer success"

"What we like best about working with Grassi is how genuinely collaborative your team is. You bring a level of professionalism and technical expertise we truly rely on, but you pair it with an approach that feels supportive rather than transactional. Your team is responsive. It always feels like you’re invested in helping us operate at our best, not just completing an audit."

"The Grassi team is highly professional, knowledgeable, and dedicated. They are always willing to help, easy to reach, and respond promptly to any questions or meeting requests."

"Professional staff - and easy to talk to. Made Board and Finance team feel comfortable that Grassi was 'part of the team'"

"Professional and responsible and at the same time on our side. I like the consistency of the time and when to tell me no. Rob Grote and Anna Poolt have been with us every year -- terrific partners with us, know what they are doing. Tax team is great also -- calm and collected, honest and also on our side -- but will not let us cross the line, if we would ever ask."

"Grassi, especially David Rottkamp, is very knowledgeable about the nonprofit I/DD industry with extensive experience with OPWDD and SED rate methodologies and requirements."
