A Different Approach

At Sonnenberg & Cunningham PA, we believe the spirit under which your company was formed is a vital part of its compliance and growth. We won’t tell you to change your corporate culture or anything else that makes your business a unique and successful enterprise.  We work to use your existing resources and practices to improve import and exporte related processes, achieve greater compliance, and more efficiently reduce costs and risks.

Unique Solutions

We treat all our clients as individuals and don’t think a one-sized-fits-all solution will work. We’ll help you develop a customized plan to your unique position, but will use our experience with large and small importers to explore the best solutions.

Quality Over Quantity

While the name of the firm has changed over the decades, it remains a small but significant firm that has focused exclusively on U.S. Customs import and export related legal services dating back to its predecessor founding in 1974.
