Armstrong Teasdale Adds Five Attorneys from Boston Employment Boutique

August 16, 2021 Press Releases

Armstrong Teasdale proudly announces the addition of five attorneys in Boston who join from employment boutique Bello Welsh LLP. The move comes as Bello Welsh, which has enjoyed a successful tenure of 18 years and earned a strong reputation in markets along the East Coast, has decided to wind down its operations and will dissolve. Armstrong Teasdale planted a flag in Boston in May 2020 and is committed to continued investment in the market and actively adding skilled attorneys to further round out the firm’s core practice areas.
