Samson Spilk, MD

American Board of Internal Medicine

Education:  Universidad Anahuac

Residency:  Pinnacle Health, Harrisburg, PA

My family and I  have called Oregon our home since 2010 and enjoy exploring its  mountains, trails, rivers and beaches. After practicing acute care  internal medicine for years my focus is now on preventing and treating  chronic medical illnesses like diabetes, high blood pressure and heart  disease. Creating and nurturing long term rapport with patients and  keeping their best interest at the forefront will be my focus. Growing  up in Mexico I can offer a bi-cultural, bilingual service.  I highly  value the all important patient-doctor relationship paramount to healthy  living. In my spare time I enjoy adventures in the beautiful Pacific NW  with my wife and 2 children.
