Yvette C. Cromwell Sosa

Yvette has always been driven by integrity and purpose. “Motivation and determination have always been factors to which I attribute my success,” Yvette has stated. “When I set my mind to do something, consider it done.” Yvette established her accounting career in 2000. Accounting came naturally to her. Throughout her years in the field, Yvette has worked with a wide variety of clients, including convention services, a law firm and a non-profit organization.

In 2020, Yvette joined HeimLantz as a fulltime bookkeeper. Her experience in many areas of accounting—accounts payable, accounts receivable, collections, financial preparation, and reporting—makes her an asset to the firm and adds a great deal of value to her clients’ experiences.

Yvette currently resides in Mitchellville, Maryland. In her spare time, she enjoys strength training and dancing. As a foster parent to unaccompanied immigrant children, Yvette adores children. She recently adopted a baby boy into her family.
