As part of our the team, you will

  • Own comprehensive calendar management across professional, campaign, and personal commitments—scheduling meetings, coordinating logistics, and maintaining a forward-looking (weekly/monthly/quarterly) plan to ensure time is aligned to top priorities and high-value outcomes
  • Plan and execute complex travel and logistics for business, campaign, and personal/family needs, including detailed itineraries, briefing agendas, ground transportation, lodging, and contingency planning; complete and reconcile expense reports accurately and on time
  • Support the CEO/principal with task management and prioritization, translating goals into actionable plans, tracking deadlines and deliverables, and proactively removing obstacles to keep critical initiatives (company and campaign) moving forward
  • Draft and prepare correspondence and materials across business and personal contexts, including emails, letters, internal communications, invitations, talking points, and meeting briefs—ensuring the appropriate tone, confidentiality, and professionalism
  • Serve as a strategic “gateway” to the executive’s time, balancing access with focus: triage requests, negotiate scheduling tradeoffs, and create win-win solutions for internal partners, external stakeholders, and campaign/community relationships
  • Maintain strong situational awareness of upcoming commitments, decisions, and sensitivities—keeping the CEO/principal prepared with timely reminders, concise briefings, and structured follow-ups to ensure nothing drops across fast-moving priorities
  • Exercise sound judgment to assess meeting and event value, recommending declines, delegates, or alternatives when appropriate; protect deep work time while ensuring high-impact relationships and obligations are maintained
  • Manage the overall flow of communication (internal, external, community, and campaign-related as appropriate), communicating directly and on behalf of the CEO/principal, and ensuring messages are routed, tracked, and answered with clarity and timeliness
  • Prioritize and respond to incoming communications (email, calls, texts, DMs as applicable) by flagging urgency, anticipating required actions, drafting responses for review, and replying on the executive’s behalf when appropriate—maintaining a consistent, professional voice
  • Coordinate campaign support activities such as event scheduling, speaker logistics, community meetings, stakeholder outreach coordination, and preparation of briefing packets—while keeping careful separation and confidentiality as needed across roles.
  • Support an active family and social calendar by organizing personal appointments, family logistics, celebrations, travel, and social commitments; track key dates (birthdays, anniversaries, school and community events) and ensure the executive is prepared and present
  • Handle special projects and personal obligations with discretion, including vendor coordination, reservations, household/admin needs, and time-sensitive requests—operating with high trust, confidentiality, and impeccable follow-through
