**Schedule: Monday - Friday, 8 am - 5 pm

**Pay Range: $25.00 - $32.00 per hour

Why This Role Matters:

This isn’t a typical admin role. You’ll act as the right hand to the Medical Director, ensuring clinical priorities turn into action across multiple sites. You’ll be the connector, organizer, and follow-through driver that keeps everything running smoothly.

What You’ll Get:

  • Competitive compensation
  • Growth exposure within a multi-site healthcare organization
  • High-impact role working directly with executive clinical leadership
  • Opportunity to be part of operational and strategic initiatives
  • Collaborative, fast-paced environment where your work is visible

What You’ll Be Doing:

Executive & Operational Support

  • Manage complex scheduling across clinical, operations, and vendor teams
  • Prepare agendas, materials, and briefing documents
  • Optimize the Medical Director’s time and priorities

Meetings & Execution

  • Capture clear notes, decisions, and action items
  • Track deliverables and hold stakeholders accountable
  • Send summaries within 24 hours and keep projects moving

Project & Workflow Coordination

  • Support clinical initiatives, workflow improvements, and accreditation prep
  • Maintain trackers, dashboards, and organized documentation
  • Coordinate across multiple sites and departments

Communication & Follow-Up

  • Triage emails and flag urgent items
  • Draft responses and ensure timely follow-through
  • Act as liaison between clinical leadership and operations

Compliance & Credentialing

  • Track licenses, certifications, and CME deadlines
  • Maintain ACR documentation and compliance calendars
  • Assist with audit preparation and internal documentation

What We’re Looking For:

  • 2 years in healthcare admin, medical office, or executive assistant role
  • Strong organizational skills—you can juggle multiple priorities without dropping the ball
  • Comfortable working in a fast-paced, multi-site environment
  • Proficient in Microsoft Office Google Workspace
  • Experience with tools like Asana, Monday.com, or similar
  • Strong communication skills (written and verbal)
  • High level of discretion and professionalism

Bonus Points

  • Experience supporting a Medical Director or physician leader
  • Familiarity with ACR, CME, credentialing, or compliance workflows

The Bottom Line:

You’ll play a critical role in enabling clinical leadership to focus on what matters most—patient care, compliance, and growth—while you keep everything else running seamlessly.

Benefits & Additional Information:

  • Medical, Dental, and Vision Insurance
  • Life Insurance and AD&D
  • Short-Term and Long-Term Disability
  • Employee Assistance Program (EAP)
  • Paid Time Off and Paid Sick Time
  • Paid Holidays
  • 401(k)
