Capstone Accounting & Tax Bolsters Central Oregon with Acquisition of Nissen & Meyer

Capstone Accounting & Tax, a rapidly scaling regional CPA and advisory platform, has acquired Nissen & Meyer - a trusted Redmond, Oregon-based firm with over four decades of history. The transaction represents a landmark expansion for Capstone in Central Oregon, enabling the firm to combine local intimacy with a broader advisory infrastructure.

Deal Summary

• Acquirer: Capstone Accounting & Tax, a full-service firm offering accounting, tax, and advisory services across the Pacific Northwest.
• Target: Nissen & Meyer, a Redmond, Oregon CPA practice founded in 1983 by Rick Nissen, with Chuck Meyer joining in 1986.
• Geographic Coverage: Nissen & Meyer will continue operating from its Redmond office, integrating into Capstone’s Central Oregon footprint.
• Service Offering: The acquired firm specializes in tax planning and preparation, advisory services for individuals, businesses, and nonprofits.
• Strategic Purpose: Capstone views Nissen & Meyer as a strong cultural match whose decades of client relationships and commitment to personalized service support its client-centric growth model.
• Continuity: The Nissen & Meyer team will remain in place, allowing existing clients to maintain trusted relationships while gaining access to Capstone’s broader resources.
• Capital & Growth: Capstone is backed by Seaside Equity Partners, providing strategic capital to support M&A and expansion.

Industry Context

The accounting and tax advisory industry continues to consolidate as platform firms target regional practices with deep client ties and technical specialization. Capstone’s acquisition reflects a broader trend: aggregating seasoned local firms to scale advisory capabilities while retaining the client trust and operational ethos that made those firms successful.

These roll-ups are particularly compelling in tax and advisory services because of the high value clients place on continuity and local expertise. At the same time, larger firms provide increased capacity, technology, and expanded service lines - offering clients a more comprehensive value proposition.

Lower-Middle-Market Roll-Up Perspective

From a roll-up strategy point of view, this deal exemplifies several key principles:

1. Value-Aligned Acquisition: Capstone is not simply adding volume; it is acquiring a well-respected, deeply embedded business that shares its client-first philosophy.
2. Retention of Leadership and Culture: By keeping the Nissen & Meyer team intact, Capstone ensures smooth integration, minimizing client disruption.
3. Operational Leverage: Capstone can apply its systems, talent, and investment to enhance service capacity - enabling Nissen & Meyer to offer more sophisticated advisory and tax planning.
4. Scalable Growth via Capital Collaboration: With backing from Seaside Equity Partners, Capstone is executing its growth plan strategically, using capital to support both organic expansion and M&A.
5. Regional Strength Building: This transaction strengthens Capstone’s presence in a key geography, allowing it to serve local businesses, nonprofits, and individuals with more depth.

Capstone’s recent M&A activity supports this playbook: earlier in 2025, it added Sargent CPA in Klamath Falls, further extending its Oregon reach.

Why This Sector Is Attractive for Roll-Ups

• Fragmented Landscape: Many high-quality regional accounting firms remain independent, offering a large pool of potential platform partners.
• Recurring & Advisory Revenue Streams: Tax, bookkeeping, and strategic advisory generate stable and recurring client engagements.
• Cross-Selling Opportunities: Platform firms can bundle tax, advisory, and business planning services to deliver more value.
• Talent & Tech Leverage: Merged firms benefit from shared infrastructure, technology platforms, training, and operational economies of scale.
• Institutional Capital Support: Investors like Seaside Equity Partners are backing professional-services firms that can scale while preserving a high-touch, local service proposition.

Conclusion

Capstone Accounting & Tax’s acquisition of Nissen & Meyer is more than a geographic expansion - it’s a purposeful scale move that marries long-standing client relationships with enhanced advisory capacity. For Capstone, the deal reinforces its growth strategy and commitment to Central Oregon. For Nissen & Meyer, it offers access to capital, broader capabilities, and continuity for its clients.

In the broader accounting landscape, this transaction reinforces the strength of a hybrid model: one that bridges local expertise with platform infrastructure - a compelling value proposition for both clients and investors in this evolving M&A environment.
