Working Toward a Century of Service

At Casey Lundregan Burns, P.C., we trace our origins back to a time before anyone could imagine the devastation of the Great Depression and our nation thought we had just been through the “war to end all wars.” William J. Landergan opened the firm soon after graduating from law school in 1924.

Even though the decade was still in mid-roar while William attended law school, he understood the importance of hard work and asset conservation. William earned his way through law school working shifts at his family’s bakery.


After starting his practice in 1926, William had little time to get established before the stock market crash triggered a financial crisis that turned lives and fortunes upside down. His service to clients and the community during these troubled times led to his election to serve as a State Representative for West Lynn in the General Court for the Massachusetts Legislature in 1935.

William continued in service as the First Assistant Attorney General and was eventually appointed the Presiding Justice of the Lynn District Court in 1952 where he served in that capacity until his death in 1970.


Judge Landergan’s daughter Pauline kept the legal business in the family when she married Joseph David Casey, after he graduated from Boston College and law school. Due to his innate litigation skills, he was simultaneously appointed to serve as an Assistant District Attorney for Essex County, while continuing to run a thriving private practice.

He also served as Legal Counsel for the Lynnfield Center Water District, the Essex Agricultural and Technical Institute and served as President of the Essex County Bar Association.


Two of Pauline and Joseph Casey’s five children, Pamela and Christopher, followed in their father’s footsteps, earned their law degrees, and joined the Casey firm. Christopher honed the firm’s focus on probate litigation, probate administration and estate planning. When Pamela was elected to serve as the Essex County Register of Probate, she left the practice to focus on Public Service. However, the family connections at the firm continued to thrive as Christopher brought his wife Sharon into the practice.

The two met during clerkships in law school, but after graduation, Sharon spent several years in-house at Fidelity Investments in Boston. When she joined the Casey firm, she served as Supervising Partner of the Real Estate Department until she was appointed to serve as The Baker/Polito Administrations Deputy Legal Counsel and Executive Director of the Judicial Nominating Commission. She later became Clerk-Magistrate of the Cambridge District Court where she continues to serve today.

Casey Family Joins Forces with Lundregan Team

In 2006, Joseph Casey passed away, and Christopher merged the Casey firm with the well-respected firm of Lundregan and Lundregan. The firm was managed by the husband and wife team of William J. Lundregan and Jane T. Lundregan, both graduates of Boston College Law School. The Lundregan firm had an outstanding reputation for probate litigation and expertise in detailed estate and tax planning.

The merger was a natural fit, taking two strong practices with a focus on family protection and building them into a team with unmatched depth of experience and devotion to client service.


Yet there was still more to come. In 2017, Attorney Allison Rose Burns joined the firm’s Litigation Department after graduating Suffolk Law School summa cum laude. Since joining the firm, Allison earned a reputation as one of the best probate litigators in Massachusetts and was named a Rising Star by SuperLawyers Magazine by her peers in 2021 and 2022.

Today, Allison Burns serves as Partner & C.O.O. while Christopher Casey continues in his role as Managing Partner and William Lundregan shares the benefit of his experience in an Of Counsel role. The team at Casey Lundregan Burns, P.C. now includes seven attorneys supported by knowledgeable administrators, paralegals and assistants all devoted to protecting families in Massachusetts with fiduciary litigation, probate administration, estate planning, and real estate assistance throughout the Commonwealth.

Since 1926, the laws have changed, and the technology involved in the legal practice has grown to levels unimaginable when our firm first started operating. However, what has not changed in over 96 years is our focused commitment to serve our clients with zeal, ardor, and consummate skill. We at Casey Lundregan Burns, P.C. are ready to put our 90 plus years of experience and dedication to work for you.
