Your Success is Our SuccessTM

At NUSSBAUM, our mission is to help our clients achieve their goals through the most professional and extraordinary client service.

  • Service, Above Everything

    Our goal is to listen—because every client has different needs and objectives. Once we understand those, we deliver personal, hands-on, customized service. We don’t cut corners and we don’t look for quick fixes. We earn your trust by providing sound advice, backed up by years of expertise and experience handling the needs of thousands of clients.

  • Breadth of Services

    As a mid-sized accounting firm with top talent and strategic alliances, we are uniquely positioned to offer all the resources and services of a large firm. We handle personal and corporate taxes along with more specialized services like business valuation, forensic accounting, and succession planning, covering all of your accounting needs.

  • Globally Connected

    As a member of the RSM US Alliance network, we have access to the resources of top accounting firms across the globe. Our accountants have in-depth knowledge of tax laws, including sales tax and payroll tax, in every state. We also assist clients with international tax needs.

  • World-Class Talent

    We hire the best in the industry. Many of our partners and employees hail from the Big 4 accounting firms and we seek out professionals with quality experience, top-notch communication skills, and passion for their jobs.

  • Partner Involvement

    Our partners are actively involved with every single account we handle. Not a single return goes out unless a partner has reviewed and signed off on it. Our clients are able to speak directly with partners at any time if they have questions or just want to get to know the people handling their finances.

  • Looking to the Future

    We are all about long-term relationships. We’ve helped and watched clients take their businesses from a home office to a skyscraper. We’ve assisted individuals in growing from just a few investments to wealth that promises security for their children and grandchildren. Because we offer such an array of services, we can grow with you as your needs change.
