Meet Our Team

Our founders are experienced clinicians who have worked together in a variety of clinical environments. We have united because we firmly believe — and our methods prove — that healthcare doesn’t have to be transactional. It is our vision to create a network of likeminded clinician groups at facilities across the country—changing healthcare for the better—one program at a time.

Hear from people we’ve served.

Feedback from the facilities we have served over the years share three common themes: We deliver. We drive change. And we do both with love. Hospital administrators and the clinicians we serve appreciate our compassionate, innovative approach because it prioritizes people while positively influencing metrics and performance.

“Their approach is truly unique. Some physician leaders sacrifice compassion for business priorities. With them, compassion was the priority and the business benefited because of it.”

Director of EM Services , 60,000 volume facility

“I’ve worked my whole career in healthcare and I’ve never run across physicians with a better understanding of how to transform an ED.”

Chief Executive Officer , Non-profit hospital.

They came into our new facility and set the bar higher than we ever could have expected. They brought metrics from nearly dismal to some of the best in the region. I cannot thank them and the provider team enough for all you have done for this community and facility.”

Hospital Administrator , Acute Care Hospital

“They wouldn’t settle for just a name on the schedule. Their leaders would go above and beyond to fill a shift themselves to avoid a “doc-of-the-day” setting. Their personal investment is clear in all they do. They consistently deliver.”

Chief Medical Officer , Non-profit health system

“I was amazed by their thoughts. We brought them in to build a more established ER group and to build trust between the ER and the primary care physicians in the community. They developed care paths with every individual PCP, and got an understanding of the patients they wanted to see and in the information needed and process that worked best for each office.”

Chief Executive Officer, Non-profit health system

“They come in and stabilize struggling ED teams. They know how to work with all members of the team from administration to all levels of clinicians to drive change.”

Chief Medical Officer , Non-profit health system

“It’s who they are and how they manage that drives change. They have a style of accountability with love that’s unique and effective.” 

Chief Nursing Officer , Regional Medical Center

They are effective because they are coaches, not dictators. They are empathetic and kind without sacrificing clarity and ability to drive results. They style of leadership very quickly makes an impact on practice culture. We saw results improve across the board very soon after they came on board.”

Chief Executive Officer , Regional Medical Center
