Since day one, service has always been a part of the Nisivoccia culture. So it’s natural for us to have built the firm on working with 300 not-for-profit organizations providing audit, tax, and advisory services.

“This is what impresses and humbles me about coming to work every day,” says Nisivoccia partner Thomas Dartnell. “Our employees care so much about their clients and their work that they take that extra step that moves our company to the next level.”

Having been so involved in the not-for-profit industry for nearly five decades, we know you face challenges that traditional businesses never have to deal with. You have your own set of tax regulations that impact everything from staffing to fundraising efforts. That’s why we are with you every step of the way. From dealing with IRS paperwork like 990 filings to meeting with management board members to review financials, consider us an extension of your team. We don’t just present information using spreadsheets and graphs, but participate in active, real-world discussions about how to improve your organization’s overall performance.

Working with established Not-for-Profits is only one of our many passions. But also, helping nascent organizations and individuals start an NFP gives us great joy. Consulting, getting organized, filing paperwork, and setting an NFP on the road to success is a hallmark of our team. Our institutional knowledge separates us from our peers in the industry.  

Our understanding of complex grant application processes, how to set-up an endowment and the relationships between boards and management comes from 50+ years in the space.  Proactive Stewardship is one of our core values and we know that our Not-for-Profit clients want to be good stewards of the funds entrusted to them to manage.

One of the most frightening words in the world of business is “audit.” We at Nisivoccia know and understand that an audit is a fact of life for all types of entities, including Not-for-Profit organizations. We work proactively with our boards and management teams to prevent the kind of missteps or problems that might raise a red flag or be cause for legal concern. We don't want to have to report a problem to the board, but instead, want to be involved along the way so the audit goes smoothly.

How We Are Different

Community Matters

Our approach to customer service is not about 9-to-5 and then call it a day. Our employees are socially conscious and aware that great thinking and analysis doesn’t stop when the day ends or the weekend arrives. It’s not unusual for Nisivoccia employees to be in the office on a Saturday morning nursing a second cup of coffee while pouring over financials. Sometimes they’re at their desks wearing their running shorts after participating in a client’s 5K race.

As much as possible we support our clients, beyond tax and accounting advice. We golf in your outings and dance at your galas. We take the time to learn about your mission, beyond what’s written on your website. It’s important to us to hear the story of who you are and why you do what you do. This helps identify areas to better serve your cause.
