Our Team

She is passionate about helping small business owners take control of their finances so they can make a bigger impact in their family, their future and their community.

Stacy’s passion for small business stems from her entrepreneurial family. From her maternal grandfather’s cattle ranch to her father’s sales firm, her sister’s online marketing business      and her mother’s crafting side hustle, business ownership runs in the veins.

Maria Kreutz

Maria (Masha) is a professional accountant with both bachelor’s and master’s degrees in the field. She assists with client bookkeeping and tax questions and paperwork. She has been with Lang Accounting since September 2018 and brings with her 4 years of experience working with small and growing businesses. She is skilled in working with personal and business tax returns.

Masha has been a vital addition to the team, allowing clients to have their tax and bookkeeping questions answered quickly so they can continue doing what they do best–work in their own businesses. She is an avid reader and volunteer at her children’s school and the Saving One Life charity.



Mekele Cole-Purvis

Mekele (pronounced like Michelle, but with a K) has been in the accounting field since her junior year of high school, when a local small business was in search of a bookkeeper. 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.
