Our Team

"With the freedom that my independent, comprehensive healthcare clinics bring, I am showing the NE and SE Portland neighborhoods that Portland Urgent Care is different because we integrate Urgent Care, Wellness Care and MobilMED for a indepth patient experience. I hand picked my staff to fit the business model that puts patient care as #1. I am extremely proud of their dedication to make sure every patient receives compassionate care, feels listened to and properly cared for."
