About Tammy

I have been a nurse in cancer care for over 25 years and have worked in a variety of cancer areas including chemotherapy, radiation, palliative, and inpatient. I have cared for people with cancer from diagnosis to end of life. My love and passion have always been in cancer care.

The Nurse Practitioner is the highest level of the nursing positions available.

My dream had always been to be that nurse practitioner in oncology and provide the best one on one care to people with cancer to the best of my ability.

I achieved the Master of nurse practitioner and now my career moves to providing that care.

There is the saying: It takes a village, and this holds true for me. That village includes all your health professionals providing the best care to you and along with that comes collaboration and communication. My goal will be to keep the lines of communication with your health professionals open.
