Cheryl M. Cronin is leaving the Boston law firm Brown Rudnick Berlack Israels, where she has been a partner for five years, to establish her own boutique firm.
Cronin, who is active in legal and political circles, has represented clients including Bechtel, former governor Jane M. Swift, and former House speaker Thomas M. Finneran.
She has also been a fund-raiser and strategist for the political campaigns of Deval Patrick and Chris Gabrieli.
A graduate of Boston College Law School, Cronin entered private practice in 1989 after working as a lawyer for the state attorney general and state campaign finance office.
In her solo practice, Cronin will continue to represent clients before government agencies.
