The deal is Mariner Wealth Advisors’ ninth announced acquisition in 2021.
The financial terms of the acquisition were not divulged.
Savant Investment Group focuses on providing financial planning, wealth management and retirement plan services.
Currently, it serves around 240 clients and has nearly $770m in Assets Under Advisement (AUA).
Savant Investment Group CEO and CIO Scott Lummer said: “This is an incredible opportunity for our firm to expand our comprehensive financial planning experience to clients and to provide career development for our employees.
“I’m excited to draw on Mariner Wealth Advisors’ broad array of services to bring even more value to our clients, from insurance and tax planning to estate and trust services.”
As agreed, Lummer will continue to lead Savant’s Emeryville office as managing director. All eight professionals will also continue with the company.
The deal, once it closes, will further bolster Mariner Wealth Advisors footprint as it seeks to achieve milestones of 1,000 associates and 500 advisors.
Mariner Wealth Advisors president and CEO Marty Bicknell said: “We’ve seen great success implementing our growth strategies, and we’re just getting started.
“Our growth has been driven by strategic acquisitions, and we look for like-minded partners who can grow with us. I’m thrilled to continue adding to our team with an impressive firm like Savant Investment Group.”
