Merit Financial Advisors has acquired Mennenga Tax & Financial, a Wisconsin-based wealth and tax advisory firm overseeing $715 million in client assets, marking Merit’s 51st acquisition. The deal strengthens Merit’s holistic planning capabilities with the addition of deep tax expertise. 

Founded by Marshall Mennenga, the firm offers integrated wealth management, estate planning, and full-service tax planning and preparation. Mennenga will join Merit as Wealth Manager, Tax Advisor, and Partner, alongside more than 35 employees, including 20 credentialed enrolled agents. The partnership provides Mennenga with enhanced technology, resources, and marketing support to accelerate growth. 

“The addition of Mennenga reflects Merit’s continued focus on providing holistic financial planning that delivers more value to our clients,” said Zach Mersberger, Managing Principal and Partner at Merit. “Their tax planning depth strengthens our approach and enables us to serve clients more comprehensively.” 

The acquisition follows last month’s partnership with Obsidian Planning Solutions, adding $476 million in assets and expanding Merit’s business succession planning services. Recent deals also include Global Wealth Advisors ($860 million AUM), Second Half Financial Partners ($225 million AUM), and AMP Wealth Management and Olympic Wealth (combined $569 million AUM)—as well as Merit’s entry into Utah through the purchase of RCM Investments.  

The transaction closed October 31, 2025. Advisory support was provided by FP Transitions. Financial terms were not disclosed. Based in Atlanta, Merit manages $19.94B across 40+ offices nationwide as of June 30, 2025.
