"Erin is a very good and experienced litigator. She is smart, practical and pragmatic. She's also doing a great job of developing newer attorneys, bringing them along to some of the things that are less sophisticated so that the work can be done at a lower rate. She's great at spotting issues too and can be honest without being abrasive, which is useful from a relationship-building perspective when it comes to other individuals at our company from a non- legal background. She's very tactful in that sense."
