Associate Reviews

  • “Firm culture is warm, friendly, and professional. We have monthly firm-sponsored events and various social events throughout the year. Lawyers and staff interact regularly and without any distinction.”
  • “Firm continuously reviews ways in which it can foster a positive and engaging culture. Weekly trainings, monthly lunch meetings, strong mentorship program, quarterly parties, etc.”
  • “Everyone at the firm is very kind and emphatic to one another. Good feelings and attitudes among staff and legal professionals.”
  • “Everyone is very kind and helpful. I have learned not to be shy about reaching out if I need help or have a question. Shareholders and senior associates will often let you figure things out on your own, but they are happy to step in if needed. Most people come into the office a few days a week and chat when they run into each other in the hallways. As more people come back into the office, firm social events are pretty well attended. There are lunches and events most weeks, and people will catch up before and after the event if there is a presentation.”
