  • Very personable.
    Very personable. Explains complicated issues in simple terms. Takes the necessary time needed to make sure we understand what's important so we can make informed decisions.
  • awesome Doctor
    I have been a patient with Dr. Sienko for over 9 years. I had stage 4 non-hodgkins lymphoma and have been cancer free for 8 years and now I see him twice a year for check ups. He was direct in his assessment of my prognosis but has been an awesome Doctor through my treatments and care.
