GROWTH MANAGEMENT SYSTEMS was founded in 1994 by Saeed Sadr, CPA, with a simple yet powerful mission: to provide high-quality financial services with a personal touch that larger firms and commercial service providers simply can't match.

For over 30 years, we've been the trusted financial partner for businesses and individuals across the country. What started as a small practice in Orange County has grown into a full-service CPA firm that has served over 1,000 clients nationwide while maintaining close relationships with our 300+ active client base. Through all that growth, you'll still work directly with our team—never outsourced overseas, never rotated to strangers. We've never lost sight of what matters most—the personal relationships and individualized attention that set us apart.

While our office is based in Tustin, California, we serve clients nationwide, including California, Arizona, Georgia, Minnesota, North Dakota, and Texas. We provide the same personalized attention to clients nationwide as we do to those who walk through our door.

Our team of dedicated professionals brings decades of combined experience in bookkeeping, tax planning, payroll services, sales tax compliance, and strategic business consulting. We're committed to integrity, reliability, and innovation, ensuring that our clients receive the highest level of care and expertise—no matter where they're located.

At GMS, you're not just an account number. You're part of our family.
