Partner Spotlight: Denise and Tina

Denise Nelson and Tina Marso could be described as polar opposites in some ways. But it only makes their business partnership stronger.

Take their background specialities, for instance: Denise comes from a background specializing in accounting and payroll while Tina’s background focuses on tax returns and preparation. Combined, they form a powerful partnership at Accounting Plus to bring both halves together to form a whole.

Denise and Tina first got together in 1993 and have been on a path of growth together since then.
