About Us

Experienced CPAs. Trusted Partners. Local Leadership.

Duffy Kruspodin is a Southern California CPA firm providing integrated tax, audit, and business advisory services to individuals and businesses. We help clients stay compliant, plan strategically, and make informed financial decisions across every stage of growth.

Trusted Southern California CPA Firm for Businesses and Families

Since 1990, Duffy Kruspodin has been the accounting and advisory firm business owners, families, and finance leaders turn to for dependable tax strategies, assurance services, outsourced accounting and long-term planning. We help clients meet today’s needs while staying prepared for tomorrow — with a team that listens, follows through, and stays involved.

More Than a Firm. A Trusted Partner.

We began in Woodland Hills with a clear purpose: to serve closely held businesses and high-net-worth individuals with practical guidance and personal attention. Today, with four offices and more than 200 professionals across Southern California and multiple states, we continue to work side-by-side with clients across industries and stages of growth.

Clients come to us for more than compliance. They want advisors who understand their business, bring the right expertise to the table, and help them make informed decisions with confidence. That’s what we deliver — through proactive planning, hands-on service, and clear communication.

Who We Serve

We partner with decision-makers who value reliable guidance, strategic insight, and steady financial support across every stage of growth.

  • Mid-sized business owners managing growth, complexity, and strategic transitions
  • High-net-worth individuals and families focused on wealth preservation, estate planning, and tax coordination
  • Closely held and family-owned businesses seeking multigenerational planning, succession support, and operational clarity
  • Professional service firms relying on integrated services across tax, outsourced accounting, HR, IT, and marketing support
  • Nonprofits and foundations requiring audit readiness, financial transparency, and regulatory compliance
  • Real estate investors and developers needing entity structuring, 1031 exchange guidance, and portfolio-level oversight

Partners in Growth

At Duffy Kruspodin, we help clients shift from reactive decisions to forward-thinking planning. Whether you’re navigating a transition, facing new challenges, or seeking more tailored support, we work with you to find the right approach — and keep things moving forward.

Clients choose us not just for compliance — but for proactive tax planning, audit accuracy, business consulting, and financial decision-making support.
