The investment advisor, with offices in Westport, CT, and Boca Raton, FL, is a 15-strong team across the two locations managing $700 million in assets.

Under the wing of HighTower, RDM will add a New York location to better serve local clients in the state.

“After 35 years in the industry and 26 running RDM Financial Group, I recognized the need for access to world-class resources, scale and a greater variety of solutions for my clients’ needs,” said Ron Weiner, chief executive of RDM Financial Group.

The drive of independent advisor channels continued to gather pace in 2015; HighTower noted that $10.2 billion of client assets landed at independent firms this year.

In October, Fort Lauderdale, FL-based firm Legacy Wealth Partners brought its $600 million in client assets onto the platform.
