Bankruptcy and Creditor Debtor Rights / Insolvency and Reorganization Law
CSG provided exceptional guidance and expertise regarding best-case and worst-case scenarios during a contentious situation with an uncooperative borrower. The litigation attorney and the corporate finance attorney with whom I worked provided exceptional feedback on numerous legal strategies that helped to drive the bank's exit strategy. Overall, my experience with CSG was very positive and I look forward to working with them again in the future.

Employment Law - Management
I worked on the opposite side of negotiation with Margaret Wood. She is a smart and zealous advocate who can disagree without being disagreeable. She did not waste time on nonsense and was collegial while never failing to represent and fight for what was best for her client. As a professional I found her demeanor and civility exceptional. Her knowledge and professionalism is without peer but consistent with the attorneys with whom I have dealt from her firm. I would not hesitate to refer a friend or colleague to her.

Health Care Law
I have worked with Nicole DiMaria for years. She is a brilliant, efficient lawyer who gets to the heart of a matter and address issues with surgical precision. Although we have always been on the opposite side of transactions, I have found her to be collaborative when appropriate and tough when necessary but unfailingly civil and professional. She is able to be adversarial without being nasty, balancing zealous advocacy for her clients with a professional and collegial demeanor with attorneys. I have and will continue to refer others to her for advice and representation.
