Honoring the Legacy of Remarkable Leaders
Building on a foundation of excellence.
At GreenGrowth CPAs, we honor the legacy of CPA firms that have built a foundation of integrity, client dedication, and excellence in their communities.

For retiring firms, this means peace of mind knowing their clients will receive the same thoughtful, high-quality service they’ve trusted for years, with the added support of expanded resources and support.
This page is dedicated to the firms whose commitment and expertise have shaped the accounting profession and paved the way for our growth at GreenGrowth CPAs. We are grateful for the groundwork they’ve laid and are committed to preserving the standards, relationships, and values they upheld. Together, we keep growing, ensuring their legacy endures through continued service and excellence.
Inspiring Journeys
Success stories from our esteemed alumni.
CSM & M
Founded in 2001 | Merged in 2024
CSM & M was a well-respected full-service accounting firm based in San Rafael, California. Known for its deep commitment to the local business community, the firm offered a wide range of services, including small business accounting, payroll, audits, tax preparation, and QuickBooks setup and training. Their focus on professionalism, responsiveness, and quality helped clients optimize their finances and achieve financial goals.
With a team of experienced professionals, CSM & M was dedicated to protecting personal assets and maximizing hard-earned dollars for individuals and families. They also helped businesses increase efficiency, stay compliant, and boost revenue and profits through their expert tax planning, compliance, and preparation services. Clients trusted CSM+M to ensure they took full advantage of deductions and credits, minimizing tax liabilities.
When the founders decided to transition into retirement, they sought a partner who would uphold their values and continue their legacy of outstanding service. The merger with GreenGrowth CPAs enabled a seamless transition, allowing clients to enjoy enhanced services while maintaining the personalized care and financial expertise they had always relied on. Today, their clients continue to benefit from the same professional guidance that has defined CSM & M for over two decades, now supported by GreenGrowth CPAs’ expanded resources and industry leadership.
“Transitioning our firm was a big decision, but GreenGrowth CPAs made it seamless and stress-free. It’s rewarding to see our clients thriving, and there’s real comfort in knowing our legacy is in trusted hands, carried forward with the same dedication.”
