RINA is a regional full service accounting and consulting firm with offices located in San Francisco, Oakland and Walnut Creek, California as well as Bellingham, Washington. RINA serves closely-held businesses and their owners, high net worth individuals and families, and many not-for-profit organizations and private foundations. RINA’s practice was founded in 1946 by Leo Helzel, an Oakland attorney and CPA, in a small office near 14th and Broadway. From its modest beginnings, RINA has grown to become one of the largest public accounting and consulting firms in Northern California and has repeatedly ranked as one of the “Top Accounting Firms in the Greater Bay Area” in the San Francisco Business Times. Our team is made up of 80 Certified Public Accountants and paraprofessionals.

In 2017 to continue a commitment of excellence to our clients and provide a true coordination of advice, RINA Wealth Management Services (RINA Wealth), an independent registered investment advisor was formed. We offer a broad range of services including retirement planning, investment consulting, portfolio management, life insurance, and a host of other financial planning services. Perhaps more importantly, it allows us to deliver a tax-efficient approach to these services due to the collaboration with our parent company, RINA Accountancy. RINA Wealth is excited to deliver this in a model that is price efficient and focused on positive outcomes via good advice.



We will be the most respected regional accounting, consulting and wealth management firm in Northern California.



RINA is a dedicated team of accounting and business professionals. We provide a collaborative environment that fosters innovative solutions. Guided by our resources and experience, our clients and our team members identify their goals and achieve their maximum potential.
