Competent on complex litigation, but communication could improve

Allyson Riemma handled a complex securities matter for our firm. Her 11 years of experience and Georgetown background were evident in her thorough analysis of the case. She is clearly knowledgeable, and her recognition in dispute resolution seems well-earned based on her strategic approach. However, while the legal work was solid, we sometimes experienced longer-than-expected wait times for responses to non-urgent emails. Setting clearer expectations on communication timelines upfront would have been helpful. For straightforward aspects of our professional malpractice exposure, her guidance was adequate, though the process felt somewhat transactional at times.
