Our Vision

We’ve come together to serve our clients through every stage, every idea, every challenge, no matter their size. We’ve expanded specialties while preserving what matters most, your relationship with the professionals you know and trust. Our team now offers a broader range of services, backed by deeper resources and specialized expertise across tax, assurance, advisory, accounting, and private client services—all delivered with the personal attention that has defined our legacy firms for decades.

Our History

The Carson City office was founded in 2006, when Darsi Casey and Nicola Neilon established Casey Neilon with a shared vision of serving entrepreneurs and their families in a more personal and flexible way. Built on decades of accounting and business experience, the firm grew through long-standing client relationships and a consultative approach rooted in trust. Today, as part of Sorren, the Carson City team continues to build on that foundation while offering clients expanded resources and deeper expertise.

Our Culture

Our culture is centered on long-term partnership, thoughtful guidance, and a deep understanding of the entrepreneurs we serve. We work closely with business owners facing complex, time-sensitive decisions, serving as a trusted advisor who brings clarity and peace of mind. As part of Sorren, we continue to invest in our people and technology while maintaining the high-touch, relationship-driven experience our clients value.
