Co-Founder & President

Senior MSK/Orthopedic Radiologist


Jeffrey L. Rosengarten, MD

Dr. Rosengarten was fellowship trained in MSK/Orthopedic Radiology and his passion in this practice segment is evident. During his first 15 years in academic practice, he won several awards for resident education, published multiple papers, and was the primary investigator or sub-investigator for over 50 research projects. He mentored over 50 residents, fellows and medical students. For 35 years he has had numerous academic appointments including at Northwestern University, The University of Illinois, and The Chicago Medical School at Rosalind Franklin University.

Dr. Rosengarten formed three independent radiology practices, built over 20 imaging centers, and co-founded or helped build several medical companies over the last 2 decades. As an entrepreneur, he participated in multiple projects on behalf of academic and community hospitals as well as his own and other radiology groups.

Dr. Rosengarten feels strongly about 2 practices that have helped ensure success throughout his business career: 1) Empowering coworkers at all levels so they feel as though they have control over their work lives;
2) Building a culture that encourages enjoyment at work.

All three of Dr. Rosengarten’s children have followed his footsteps into medicine and radiology, in particular, based on the passion that they observed their father maintain through both good times and challenging situations. Dr. Rosengarten feels that the support he has received from the people that he loves—family and friends—is most responsible for his personal success.

He loves world travel, meeting and learning from all people, experiencing new and varied cultures, and feels that lifelong learning is vital.

“I never thought that I would be saying that I have been practicing radiology for 35 years. I am still passionate about the same things 35 years later: patient centered care, with the highest quality, best service, and the lowest possible cost. That’s it! That equals the best value for the patient!”
