Scott Sims, president and founder of The Pinnacle Group, said in a prepared statement.

Financial details of the transaction were not released.

Founded in 1994, Pinnacle specializes in retirement planning. an area of professional focus that Mariner is seeking to expand and scale through its retirement plan solutions and platform, which is designed to aid businesses in managing their employer-sponsored retirement plans for employees, the release said. The news release also said that by acquiring Pinnacle, the firm’s high volume of CPA referrals would complement Mariner’s existing CPA Alliance.

I’m excited to see what we can accomplish together.”

ECHELON Partners, an investment bank headquartered in Manhattan Beach, Calif., advised the owners and founders of The Pinnacle Group on the transaction, which is expected to close on September 24. Once it does, Pinnacle will rebrand under the Mariner Wealth Advisors name, while Sims continues to lead his firm’s Cincinnati headquarters.
