Commonwealth Financial Network  has added three independent financial advisory firms as affiliates.

Commonwealth will be the broker-dealer for Ellis & Ellis Investment Management, Ingargiola Wealth Management Group and Cornerstone Investment Group. All were formerly affiliated with LPL Financial.

The three will add $255 million in assets to the $71 billion under management by the 1,500 independent registered representatives that are part of Commonwealth, which is based in Waltham, Mass.

Ellis & Ellis, based in LaGrange, Ga., has six advisors and $150 million under management. It is led by the father and son team of Robert and Will Ellis.

Ingargiola Wealth Management Group, based in Dunmore, Pa., is lead by Lou Ingargiola and Sean McAndrews and has $70 million under management.

Cornerstone Investment Group, based in Pikeville, Ky., is led by Ronnie Spence and manages $35 million. 

The three firms “are industry leaders who share our strong cultural values and client-centric business model,” says Andrew Daniels, Commonwealth’s managing principal of field development. “We look forward to being a supportive partner to them as they enhance their practices and achieve their strategic growth objectives.”
