How do you provide holistic care?

An important part of providing holistic care is respecting people from all walks of life. It’s about making shared decisions, not assigning a one-size-fits-all approach to breast cancer treatment or surveillance. Shared decision-making starts with us getting to know each other. I always ask questions instead of assuming I know anything about who you are and how breast cancer is affecting you personally. A diagnosis can be far-reaching in the ways it changes your life. Beyond the obvious physical issues, there are psychological, social, spiritual and practical concerns that commonly crop up. I strive to acknowledge those issues and help you adapt.

What’s it like to work with you?

I enjoy meeting you where you are, whether you’re feeling calm, uncertain or in the grips of a crisis. Each person’s breast issues manifest differently so I’m especially interested in listening to your specific experience and taking that into account before recommending a plan. What you can expect from me is compassion and straightforward clinical knowledge about how to address your concerns. Above all, I believe in creating a safe, comfortable experience for anyone who walks through my door, including people of all genders.

Provider background

Breast cancer

As an advanced registered nurse practitioner (ARNP), I specialize in breast oncology and women’s health. My background includes caring for patients in the intensive care unit and serving as a sexual assault nurse examiner. Today, my practice spans breast cancer screening and diagnosis as well as the treatment of benign breast problems. I provide surveillance for survivors and patients at high risk of developing breast cancer due to genetic mutations or family history. I also work closely with breast cancer surgeons to provide follow-up care and perform in-office procedures. Through SCCA’s NOW clinic, I offer guidance to patients newly diagnosed with breast cancer before they meet with their treatment team.

Clinical trials

We make promising new treatments available to you through studies called clinical trials led by SCCA doctors. Many of these trials at SCCA have led to FDA-approved treatments and have improved standards of care globally. Together, you and your doctor can decide if a study is right for you.

Your care team

At SCCA, you receive care from a team of providers with extensive experience in your disease. Your team includes doctors, a team coordinator, a registered nurse, an advanced practice provider and others, based on your needs. You also have access to experts like nutritionists, social workers, acupuncturists, psychiatrists and more who specialize in supporting people with cancer or blood disorders.
