About Us

We are a boutique management strategy consulting firm led by former McKinsey consultants. Our work spans high-impact engagements with private equity firms, Fortune 500 companies, and healthcare innovators. With a fast-paced, high-performance culture, we pride ourselves on delivering the rigor of top-tier consulting with the flexibility and focus of a smaller team.

The Role

We are seeking a highly capable, detail-oriented Executive & Personal Assistant based in New York City to support both firm-related and personal needs. This is a hybrid role that combines professional assistant work - such as document prep, email management, and scheduling - with personal support including errands, returns, and basic household coordination. This is a contract or part-time opportunity with the potential to expand into a more integral role depending on interest and performance.

Key Responsibilities

Professional Support (Firm-facing):

• Draft and format professional emails, presentations, and documents
• Calendar and inbox management
• Light project coordination and client-facing logistics
• Support consultants on day-to-day administrative tasks

Personal Support (Home-facing):

• Coordinate in-home services and vendors
• Provide on-site support for household needs (e.g., organizing, deliveries)
• Handle occasional travel planning or reservations

Who You Are

• Based in New York City and available for in-person support on a weekly basis
• Previous experience in a professional services or executive support setting
• Highly organized, proactive, and comfortable juggling multiple workstreams
• Strong communication and writing skills; polished and discreet
• Interested in being part of a high-performance team and growing within the role
• Comfortable navigating both professional and personal boundaries with discretion

Why Join Us

• Work alongside ex-McKinsey consultants and gain exposure to fast-paced strategic work
• Hybrid role that combines structured, high-level assistant work with flexibility
• High-growth trajectory for the right candidate (could evolve into Chief of Staff, Ops Lead, etc.)
• Opportunity to learn from and support a team driving impact across industries
