Gwen's tax practice includes advice to individuals, businesses, nonprofit entities, and local governments on federal and state tax issues. She is experienced in corporate, partnership, and individual taxation matters, as well as the income tax and transfer tax issues of trusts and estates. Part of Gwen's practice focuses on the "sharing economy," including advice to cooperatives and cost-sharing entities, the creation of collaborative agreements among public and private entities, and innovative grant- and gift-making techniques. Gwen also addresses international tax issues, including foreign investment in businesses and assets, as well as FACTA and FBAR compliance.
In addition, Gwen is the Executive Director of an Oregon state agency that is housed at Tonkon Torp: the Oregon Facilities Authority. In this work, Gwen works closely with the Office of the State Treasurer to help Oregon nonprofits access low-cost financing for the acquisition of facilities and equipment through the issuance of revenue bonds. The Oregon Facilities Authority has issued over $3 billion in bonds in its 23 year history.
Gwen's clients appreciate her ability to listen and to hear not only to what is said, but what is not said, a critical element in helping them achieve their long-term objectives as well as short-term goals. Clients say she deploys a unique combination of intelligence and common sense to help them solve their legal problems, without forgetting the all-important human side of any problem.
Gwen began her law career at the Dallas, Texas law firm of Akin Gump, and then spent a number of years teaching law school. She taught tax law at Willamette University College of Law in Salem, Oregon for many years before joining the Eugene, Oregon boutique firm of Speer Hoyt PC. She came to Tonkon in 2008.
