Executive Leadership, On Demand
Who We Are
Impactive Consultants is a fractional executive advisory firm serving physician groups, healthcare organizations, and mission-driven nonprofits. We give growing organizations senior leadership in growth, operations, marketing, and people strategy without the cost of a full-time C-suite.
Our principals have built and scaled physician enterprises, medical technology companies, and multi-site nonprofits across the New York metro region and beyond. We don't hand over a slide deck and walk away. We sit inside your leadership team, build the plan, and drive it to measurable results.
Insight. Strategy. Execution. That is how we work, and it is why our clients keep us on retainer.
01 Insight
We start by listening. We review your numbers, your team, and your market to find where growth is stalled and where the fastest wins are.
02 Strategy
We build a clear, prioritized plan with owners, timelines, and the dashboards you need to measure what matters each month.
03 Execution
We roll up our sleeves and drive the work alongside your team, from recruiting and launches to campaigns and contracts, until the results show up.
Why Impactive
Not an agency. An extension of your leadership team.
Agencies run campaigns. We run growth. This is fractional executive leadership, not a fractional CMO. When you need senior judgment on recruiting, partnerships, operations, and revenue, not just more marketing, that is where we come in.
Already working with an agency? We often lead the strategy and manage agency partners so their work drives the results that matter to your organization.
