How “Emerald” Got its Name

Emerald comes from the city of dreams – Emerald City in the Wizard of Oz. Their slogan is ”Where the dreams that you dare to dream really do come true.” They realize their dream every day by having their own very successful QuickBooks® consulting business.

​Within this dream, Maureen and Audrey help others start and grow their own dream businesses. The rainbow in their logo is a visual reminder to you of YOUR DREAM. They are both Irish, so the Emerald and rainbow go hand in hand with the country of their ancestors.
