Who We Are
Oregon Medical Group’s primary care providers, pediatricians and specialists are devoted to providing convenient, coordinated and comprehensive medical care to the people of Eugene, Springfield and Lane County.
Convenience: We know that if we make it easy to see a doctor, our patients will be healthier. To help, we offer appointments in 10 locations across the community, including an After Hours clinic that offers evening and weekend appointments and two NOW Immediate Care walk-in clinics. For patient convenience and speed of care, clinics offer on-site labs and imaging. See a full list of our clinics here.
OMG prides itself on an uncommonly coordinated approach that puts patient care at the forefront of its efforts. We know that if we make it easy to see a specialist, the continuity of care each patient receives will be superior. Our providers work as a team, so you can be certain that your doctors and care team are collaborating to ensure high-quality and thoughtful care.
In addition to the core services provided by our family practice, adult medicine and pediatricians, our specialty providers include internal medicine, orthopedics, sports medicine, OB/GYN and dermatology. See a full listing here.
We are led by CEO Karen Weiner, MD and a board that includes practicing physician owners as well as community members. Everything we do is calibrated to achieve our vision:
Together, we help you live your healthiest life.
This sounds easy enough, but the approach was ground-breaking. It meant full buy-in by everyone on the team, and a deep commitment that would take a long view, rather than being satisfied with short-term successes. Over the years, this physician-led and patient-directed approach has made it easy to act on the best interests of our patients.
