Lauren Mack joined T&M in November 2017 as Managing Director of Investigations. Since joining, she has helped clients across sectors and industries meet their diverse investigative goals and challenges. For law firms, Ms. Mack provides expert litigation support services including deposition support, witness interviews, data analysis, legal strategy consulting and expert witness referrals. In support of academic institutions, she conducts discreet investigations into issues concerning students, faculty and staff. For parents of college-bound children, she oversees inquiries into teenagers’ social media presence, helping to uncover and take action on any postings that could potentially negatively impact their college admissions process. Additionally, for T&M’s corporate and private clients, she oversees due diligence investigations and background checks for both employment and non-employment purposes.

Prior to joining T&M, Ms. Mack spent three years as a Partner with Moses & Singer LLP, where she was active in the Manhattan firm’s White Collar Criminal Defense, Government Investigations and Healthcare Litigation practice groups. In that role, she structured and negotiated pleas, corrective action plans and settlement agreements for health care providers, insurers, and individuals facing government investigations, prosecutions and civil lawsuits.  

Ms. Mack began her legal career at the Kings County District Attorney’s Office in Brooklyn, New York. During her 25 years as an Assistant District Attorney, she screened incoming matters, indicted and tried numerous court cases, negotiated pleas, monetary penalties, and analyzed and led complex investigations. She was also called upon to train investigators at various city agencies and cadets in the police academy. Ms. Mack’s success led to multiple promotions, including to Chief of the Health Care Fraud & Abuse Division, a 35-person unit which she founded, Chief of Public Assistance Crimes Unit, Chief of the Crimes Against Children Bureau, Deputy Bureau Chief of the Grand Jury and Chief of Investigations, where she and her team recovered more than $10 million from defendants involved in fraudulent matters. Working in these various units enabled her to gain prosecutorial experience in a wide range of subject matters and led her to be promoted to Executive Assistant District Attorney, the final title she held until leaving the Office.  

Ms. Mack’s prior joint investigative experiences alongside multiple government agencies and task forces has solidified her reputation for integrity, thoroughness and skilled strategic analysis, all of which positively impact her business relationships. With experience in public and private practice, she offers clients the unique ability to understand the perspective, strategy and acumen of both defense attorneys and prosecutors.
