Laurence D. Mass Attorney at Law is a plaintiff-focused legal practice dedicated to representing individuals who have been harmed, not large corporations. Specializing in advocacy for those wronged by professional misconduct, negligence, or breaches of duty, the firm stands out for its commitment to justice and client-centered representation.
Larry Mass works exclusively with plaintiffs on a contingency fee basis, meaning clients pay no upfront attorney fees—compensation is received only when the client recovers money. With extensive experience in civil litigation, he handles cases involving professional malpractice, fiduciary breaches, and personal injuries, offering personalized, one-on-one legal support from case evaluation through discovery and resolution.
