  • Support senior leadership in the hiring process, including interview coordination and onboarding.
  • Provide training to junior staff, enhancing team performance and mentoring administrative personnel.
  • Plan and coordinate offsite meetings, conferences, and special events.
  • Act as the primary point of contact for high-level external stakeholders, maintaining professional relationships.
  • Represent senior leadership in meetings, conferences, and events as needed.
  • Work with various departments to ensure smooth execution of initiatives and facilitate communication.
  • Assist with other duties as assigned within the designated department. Travel as required.
