Prior to joining First Republic, McCabe worked at Goldman Sachs Trust Company and Neuberger Berman Trust Company. He is also a member of the Philadelphia Estate Planning Council's board of directors.

The firm said the new entity will allow clients to "realize the advantages of Delaware trusts," as they can offer significant income and estate tax benefits, in addition to greater flexibility in establishing multi-generational trusts, including dynasty trusts.

A number of firms have made hires to trust businesses in the first part of this year, as developments in the US tax code have driven demand for these services.

At the start of the year, Dan Lindley, president of The Northern Trust Company in Delaware and chief fiduciary officer of its private client business in Guernsey and Cayman Islands, anticipated that 2012 would be highly "tax-driven" for private clients.

His predictions were due to the 2010 Tax Relief Act, which he said had ushered in “unprecedented” opportunities to make lifetime gifts – but only within a two-year window set to expire at the end of this year.

Earlier in 2012 Key Private Bank, another regional bank and part of New York-listed KeyCorp, established a Delaware national trust company to work with its wealth clients and prospects on asset protection and tax savings.

Meanwhile, Cambridge Bancorp named Susan Martore-Baker as president of its subsidiary  Cambridge Trust Company of New Hampshire, while Neuberger Berman hired Diane Lederman as president and chief executive of Neuberger Trust Company earlier this month.

First Republic already has trusts in California, Connecticut, Massachusetts, Nevada, New York and Oregon, with over $4.6 billion in assets, as of 31 December 2011.

First Republic Trust Company of Delaware is part of First Republic Private Wealth Management and can serve as trustee, successor trustee, or co-trustee on various personal trusts, including marital, irrevocable and charitable trusts. The bank said it also serves as executor or co-executor for estate settlements.
