About me

As Managing Attorney at Pollack Law Group, P.C., Attorney David Callahan is known for his ability to step outside a case, see the "big picture" and identify a solution that will satisfy both sides. Direct, practical and efficient, he has a knack for getting everyone to focus on the issues and the end goals, helping to resolve cases as quickly as possible so people can move on with their lives.

While he prefers to settle cases amicably, out of court, Attorney Callahan is a skillful litigator. Because of his experience and reputation in the courtroom, clients often seek his representation in matters that are complicated or adversarial and will likely require court intervention or a trial.

Attorney Callahan also serves as a mentor and advisor to the growing team of PLG attorneys, helping to maintain the exceptional client service and representation expected by clients of Pollack Law Group, P.C.

David Callahan is a graduate of the New England School of Law and Becker College. He is licensed to practice law in Massachusetts and Connecticut.
