Seiler LLP was founded in 1957 by Donald Seiler and remains a locally-owned firm with offices in San Francisco and Silicon Valley. Over the years, Seiler has become the preeminent firm in Northern California providing tax and estate planning, charitable gift planning, family office and consulting services to high net-worth individuals and families. Seiler specializes in tax, assurance and consulting services for private companies, real estate clients and non-profits, and is also a leader in family law and commercial litigation consulting services.

While Seiler LLP's client base resides mostly within California, our reach extends worldwide. We service our clients' multi-state and international needs through our membership in London-headquartered HLB International, a global accounting and consulting firm. Through HLB International, we maintain close affiliations with locally owned CPA firms in most major U.S. metropolitan areas and with regional accounting firms in more than 90 countries. Since we never give or take fees, commissions or referral fees, our professional services are provided with our clients' best interests in mind.

We're proud of our clients, many of whom have long-term relationships with the firm because of our high standards of service. Most have achieved prominence in such industries as real estate, retail, technology, investment advisory services, construction, import/export, hospitality, professional services and wholesaling. They include entrepreneurial individuals and families with a high net worth/net income and their related family entities and businesses.

And we're equally proud of our staff. From the beginning, we've empowered our professionals with career-focused accounting programs in order to better serve our clients. As a result, Seiler professionals grow and stay with us, producing a remarkable record of longevity and performance that has led the leading industry publication to name us to the "Best of the Best" list for the 6th consecutive year, longer than any firm in the western U.S.A..
