Jeanne Grube, CPA
Client CFO
Jeanne Grube, CPA, obtained her BBA in accounting from The University of Texas at Austin. She started her accounting career with Ernst and Young after college and her experience with EY, led to a trust officer position and later a controller position with a local architect firm. Motherhood and the desire for a more flexible work arrangement led her back to an auditing career with Blazek & Vetterling, and it is where her love and passion for the nonprofit community developed. After spending over 15 years with Blazek & Vetterling, she desired to apply her experience in a role with MWCPA that could more directly assist clients in developing policies and processes that provide strong controls, accurate reporting, and a smooth annual audit process. As an avid shell collector, she is known to spend hours on the beach searching for the perfect shell. Jeanne also enjoys traveling with friends and photography.
Jennifer Skobel, CPA
Client CFO
Jennifer has a BBA in Finance from the University of St. Thomas, a Certificate in Accountancy from the University of Houston, and ultimately her CPA license. Her career started in finance, with a transition to accounting in the audit department of a public accounting firm, and then into the corporate sector. Her career was put on hold when she moved overseas for her husband’s career to SouthEast Asia for 7+ years. When they moved back in 2017, she returned to the accounting world. She was blessed to work with Cox & Associates CPAs (later merged with Ratliff + Associates, P.C.) where she was introduced to the nonprofit sector, gaining valuable knowledge and training in preparing their 990 tax returns. Assisting nonprofit organizations and those that lead them to focus on what they do best in accomplishing their mission has provided her fulfillment in what she does and drives her to continue this path.
