She has an associate’s in accounting, a bachelor’s in marketing, and a master’s in human resources management. Additionally, she holds professional certifications in HRM. Mekele has worked most of her career in various industries in corporate America, but it never gave her the same satisfaction as working with small business owners; everyday is something new and challenging. She is a self-described nerd and loves all things analytical, but she is not your stereotypical accountant profile and is anything but boring; she’s a great storyteller, too!

Away from work, she has volunteered her time in many capacities within her community, including holding a position as a commissioner on the City of Chandler’s Housing and Human Services Committee. She also enjoys cooking, reading, and spending time with her husband, son and dog.

Nikki’s bookkeeping career began, at a young age, in the restaurant industry. Her journey took an exciting turn when a local CPA firm was looking for someone with a restaurant background. It was a perfect fit! Guided by the firm’s resources, she rapidly expanded her expertise across various industries, becoming a versatile asset. With the tools and support of a large firm, Nikki was able to grow her knowledge of bookkeeping in a variety of industries. With the increasing use of in-house accounting programs and the support of fellow employees, Nikki took on the role of QuickBooks consultant.

To this day, she enjoys helping and supporting businesses, of all sizes, with the knowledge and process of accounting and utilizing technology to its full use. Nikki recently moved back to the Pacific Northwest to be closer to family and friends.
