All about Northwest Minimally Invasive Surgery

We are a patient-focused surgical clinic. We have three locations to serve you, and each of our board-certified surgeons is an expert in multiple specialties.

We opened Northwest Minimally Invasive Surgery in 2017 because we identified a need in our community. We realized there were few if any places for patients to turn in order to receive expert, cutting-edge surgical care in a setting that also prioritizes patient comfort.

We dedicate ourselves each day to ensuring a warm and welcoming setting for those who entrust us with their care. And that environment allows our world-class surgeons to do their best work while keeping patient comfort at the forefront of their minds.

Learning that surgery is a medical necessity is hardly a pleasant experience. But at Northwest Minimally Invasive Surgery, you can trust our accomplished and compassionate team to provide expert surgical care and healing with an emphasis on your comfort and wellbeing.

Bottom line: Our patients are the sole reason our practice exists, and our surgeons are laser-focused on healing, health, and overall wellbeing.
