Jacqueline T. Colclough


Jacqueline Colclough is a partner at Regan Zambri & Long. She is a magna cum laude graduate of St. Anselm College, where she earned her Bachelor of Science degree in Nursing in 1988. After receiving her license to practice as a registered nurse in Virginia, she received her law degree from the Columbus School of Law, Catholic University of America, in 1991. She is admitted to practice in the State of Maryland, the District of Columbia, the State of New York and the U.S. District Courts for the District of Columbia and District of Maryland.

Prior to joining Regan Zambri Long, PLLC in 2005, Ms. Colclough worked as an associate with Thompson Coburn LLP, Washington, D.C., and Lamb & Barnosky, LLP, Melville, New York, where she represented corporate clients in transactional and regulatory matters for more than ten years. It was during this time that she developed and refined her negotiating and litigation skills as the lead attorney in multimillion dollar transactions.

With a goal to ultimately combine her medical and legal expertise, Ms. Colclough returned to the practice of nursing to strengthen her clinical skills. She worked as a staff nurse at a Northern Virginia hospital in the area of obstetrics and neonatology for several years. Ms. Colclough then chose to join Regan Zambri Long, PLLC in order to use her many years of nursing and legal experience in medical malpractice actions for the benefit of those who have been seriously injured due to the careless and preventable errors of others.

Ms. Colclough's practice is rooted in her belief that patient safety considerations should never be compromised in the health care setting and that victims of medical negligence are entitled to fair and just recompense for their injuries, particularly when those injuries are life-altering. Her practice is further focused on achieving justice for patients who have been severely injured and families who have tragically lost loved ones through no fault of their own.

Ms. Colclough is a member of numerous professional and other organizations, including the American Association for Justice, the District of Columbia Trial Lawyers Association, The Maryland Association for Justice, The Virginia Trial Lawyers Association, The American Health Lawyers Association, The American Association of Nurse Attorneys, the American Nurses Association, the Maryland State Bar Association, the District of Columbia Bar Association and the alumni associations of St. Anselm College, the Columbus School of Law and Thompson Coburn LLP.

Ms. Colclough was born in Manchester, New Hampshire and lives in Northern Virginia with her family.
