About Oregon Specialty Group


Our History

Oregon Specialty Group provides advanced treatments and compassionate care through our four practices: Oregon Oncology Specialists, Oregon Rheumatology Specialists, Oregon Infectious Disease Specialists and Oregon Specialty Infusion

We also support independent practices with business services, so they can remain independent and continue to provide high quality care for our community members close to home, for the lowest cost. 

For more than 20 years, we have led the way in offering innovative, personalized care in a warm, welcoming environment that always puts patients first.

As one of the few remaining physician-owned practices in the state, we are committed to bringing the highest level of compassionate care to Oregonians who need it. Because our true specialty is caring for you. 

At our core, we take great satisfaction in making top-notch healthcare more accessible to you in the comfort of your own neighborhood. Our approach emphasizes affordability, ensuring that patients can prioritize their recovery without financial worries. We deeply appreciate the growth and success of independent practices, as they provide patients with a range of options within their communities.

Our Purpose

We take care of people.

We believe caring for patients means serving the community we share. Treating patients and each other with compassion, honesty and respect. Working as hard to promote health as we do to treat disease. And doing our part to ensure that Oregon is a healthier place for everyone. That’s why we do everything we can to support excellence in our practices and with our partners. Truly exceptional care begins with patients and expands to families, to each other and to the community. It’s what we do best at Oregon Specialty Group.
