J Garth Rasmussen, CPA

Certified Public Accountant in Corona, California

John Garth Rasmussen, CPA, is committed to delivering customized financial services that meet the unique needs of both businesses and individuals. With extensive experience in tax preparation and compliance across a broad range of non-governmental entities, I ensure that each client’s tax obligations are managed with accuracy, diligence, and personalized attention. In addition, I provide specialized financial accounting and bookkeeping services tailored to each client’s specific requirements.

My professional path is deeply rooted in a proud, multigenerational family legacy in accounting. My grandfather, Joseph Rasmussen, established the foundation of our family’s long-standing commitment to integrity, hard work, and exceptional service. He built enduring client relationships, many of which continue today.

This tradition was strengthened by my father, John Rasmussen, who dedicated more than 45 years to the accounting profession. His deep expertise and steadfast commitment helped expand my practice’s reputation for reliability and personal care. Many of today’s clients worked with my father for decades, and several even worked with my grandfather before him. Their continued trust is a testament to the values and consistent quality that defines my firm. My father still lends his insight from time to time, further enhancing the services I provide. Since formally establishing my practice in 2018 through a buyout of my father’s business, I have continued to deliver dedicated, personalized solutions to a diverse and loyal clientele.

I earned a Bachelor of Business Administration with a concentration in Entrepreneurship and Free Enterprise from Graceland University in 2001, forming the foundation of my professional career. Following a successful managerial tenure with Walgreens, I transitioned into the accounting field in June 2007, joining John Rasmussen, DBA Rasmussen CPA’s. To further advance my expertise, I completed additional coursework at California State University, Los Angeles, fulfilling the educational requirements to sit for the CPA Exam. In November 2011, I earned my Certified Public Accountant license from the State of California, an important milestone in my professional development.

Over the years, I have built extensive experience in individual taxation, corporate taxation, commercial and residential real estate, and not-for-profit organizations. I have represented both individuals and companies in a variety of tax matters before the Internal Revenue Service and the Franchise Tax Board. I maintain active membership in the California Society of Certified Public Accountants and the American Institute of Certified Public Accountants, enabling me to stay current with evolving tax laws, best practices, and industry standards.
