She has a great deal of experience advising clients on benefits issues arising in corporate transactions. Additionally, she assists clients with various participant disclosures and communications, negotiating contracts with benefit plan service providers, such as third party administrators, consultants, and investment advisors, drafting and amending health and welfare plans, pension plans, employee stock ownership plans (ESOPs), and 401(k) plans, and ensuring those plans remain in compliance with the complicated requirements imposed by the Employee Retirement Income Security Act (ERISA) and the Internal Revenue Code.

Tiffany has represented a number of large public companies before the Internal Revenue Service (IRS) and the Department of Labor (DOL), in connection with employee benefit plan audits, and a significant part of her practice involves assisting companies of all sizes with the correction of plan failures through the DOL’s Voluntary Fiduciary Correction Program and the IRS’s Employee Plans Compliance Resolution System (EPCRS). Tiffany has filed numerous voluntary correction program (VCP) applications and has assisted plan sponsors with all aspects of plan correction matters. She also assists companies with internal reviews of their benefit plans and has deep experience in advising employers on their fiduciary responsibilities with respect to their benefit plans.
