    Biography

    Theresa has been providing quality care as a Nurse Practitioner to oncology/nematology patients in the in-patient and outpatient environment for more than 30 years.

    She implemented the hereditary cancer syndrome program, which provides assessment and counseling services for high-risk individuals and their family members. Prior to her tenure as a NP, Theresa attended patients as staff nurse for Redwood Regional Medical Group from 1996 to 2002 and is now part of St. Joseph Health Medical Group, providing clinical expertise and training with the majority of her focus on solid tumors (example breast, lung, colon etc), as well as lymphomas, CML, MDS, and CLL. She is also specialty trained to perform bone marrow biopsies.

    Teresa loves to educate patients, families, and colleagues - when she is not seeing them in clinic, she gives educational talks on cancer genetics, metastatic colon cancer, CML, MDS, and breast cancer. Theresa is an extremly caring Nurse Practitioner and takes pride in caring for the oncology patient and their family in the outpatient setting, including the administration of chemotherapeutic agents and support measures as needed.
