He helps his clients identify the issue and works with his team and clients to develop a solution. Whether it’s preparing tax returns, or multi-state tax planning and preparation, Eric is there to advise his clients every step of the way, keeping them from getting overwhelmed. He works with CFOs and business owners on planning, budgeting, and forecasting to help expand their business responsibly.

Eric previously worked for a small firm that Mercadien eventually acquired. He worked in all practice areas of the firm, including estate and trust administration, multistate corporate taxation and the nonprofit sector. He worked in both the tax and accounting departments on audits, reviews, and compilations of financial statements. Eric uses his well-rounded experience to continue to grow himself and his team at Mercadien.
