  • Assist with planning and execution of office events
  • Provide general administrative support such as answering phones and registering employees for training and events
  • Maintain office cleanliness, organization, and overall functionality

You Have:

  • 2+ years of facilities or administrative assistant experience in a professional office environment
  • Experience working in a role that requires collaboration, client service, confidentiality, attention to detail, and problem solving
  • Proficiency with Microsoft Office, Outlook, Teams, and calendaring tools
  • A valid driver's license and access to a reliable personal vehicle for regular work-related travel
  • Ability to lift up to 40 pounds and perform physical tasks as needed.
