Putting People First
IES is proud to be a physician-founded, physician-owned, and physician-led group. We do not have outside investors borrowing from tomorrow to create opportunity today, so we can perform without non-clinicians dictating what is right for our patients. We are committed to doing the right thing for our clinicians, patients, and communities.
Healthcare The Way It Should Be
A trusted partner to a vast network of over a thousand clinicians and over two million patients. We are sustainably funded through responsible growth and reinvestment. Our leadership is thoughtful about growth, and we have created a culture that fosters a career you can grow with. Most importantly, we are committed to always doing the right thing.
Partnerships Built For Trust
Our purpose is patient-centered healthcare. Partnering with physicians, hospitals, and healthcare leaders, we create a culture of excellence through leadership, research, education, knowledge translation, and data-driven decision-making. We strive to be the benchmark against which all others are measured, delivering exceptional results.
