She joined CTCA® in November 2017 and is dedicated to treating patients with all stages of cancer.

“I want my patients to know that I am willing to help in any way possible, and I try to take as much time as needed to inform and answer questions,” says Leese. “I also acknowledge the importance of my patients’ emotional, mental and spiritual needs. I strive to help my patients maintain an optimal quality of life while going through cancer treatment.”

Patient ratings
Star ratings and comments are only available for medical, radiation and gynecologic oncologists. Gynecologic surgical offerings are not included at this time due to a different survey tool required to evaluate these services. CTCA uses a validated Press Ganey® survey, which captures patient experience feedback for the primary oncology services of chemotherapy and radiation therapy at our comprehensive care and research centers. Following industry best practice, star ratings and comments are only published for physicians with a minimum of 30 completed patient surveys.
