About Mark Dziemianowicz and Banner Safety Practices

Care Philosophy

I believe in offering patient-centered care. My role in a patient's cancer journey is to understand a patient's goals and offer the best possible treatment options to achieve these goals. I strive to give patients the time they need to feel comfortable with their diagnosis and treatment options.

I am committed to a wholistic approach to cancer care. I work closely with the multi-disciplinary cancer team to support patients through their cancer journey and to provide high-quality, compassionate, and thoughtful care.

Interests & Activities

I enjoy spending time with my friends and family, volunteering, and traveling. I also enjoy many outdoor activities including cycling (road & mountain), hiking, backpacking, and skiing. I am an avid football fan and played 4 years of college football.

All Banner facilities are pleased to provide interpretation services to our patients and their companions for no charge - just ask when you arrive.

    Dr. D is a great explainer. He made everything understandable, included me in decision making as to what kind of treatment I wanted and fully explained the process. He is a great doc. I have complete confidence in him and his team.
