tax experts.


Strategic tax preparation, planning, and controversy representation for individuals, families, and business owners with advanced estate and legacy planning as part of a long-term strategy.

Individualized Attention

We take the time to get to know our clients and their goals. We ask questions to ensure we are not missing present or future opportunities for tax savings and tax planning.

Technology Fueled Practice

We run a paperless office, which means you will have access to electronic copies of your documents whenever and wherever you need them.

Communication

Our firm provides year-round availability for tax preparation, tax planning, and related matters, with an emphasis on clear and reliable communication through phone, text, email, and our secure client portal.

Fair and Transparent Billing

We offer many flat-rate services and reasonable hourly rates that provide clarity to your billing. We prefer to surprise you with our exceptional services and work, not bills.

    Tiffany R. Guillemaud, Esq.

    Tiffany is not a typical attorney. Her unique combination of technical know-how, practical experience, and human understanding allows her to work with clients of all backgrounds, including high net worth individuals, working families, creatives, and business owners.

    Tiffany is an Enrolled Agent and Attorney who has spent years learning the ins and outs of tax law, business strategy, and estate planning. Her clients trust her because she can simplify a complicated issue into straightforward, digestible, and easy-to-follow advice that truly makes a difference.

    Adaptable and steady, Tiffany is equally comfortable advocating in formal proceedings or guiding clients through important decisions in a more personal setting. Her work is defined by clarity, discretion, and an approach that empowers rather than overwhelms.

    Tiffany is admitted to the California State Bar and the United States Tax Court, allowing her to support clients through both the resolution of complex tax matters and proactive planning.
