Treatment Philosophy

Head and neck cancers are uncommon and can drastically alter a person’s ability to eat, speak, and breathe. An experienced, dedicated multidisciplinary cancer team involving surgery, radiation, and medical oncology is paramount to treating patients while optimizing their quality of life. At Fox chase cancer center, we have the benefit of having a close-knit group of dedicated physicians working collaboratively to offer many innovative treatment strategies as well as clinical trials to optimize patient care.

I believe that each patient is unique, and that my extensive training at the University of Toronto and MD Anderson Cancer Center has provided me a deep understanding of treating patients with complex problems. In particular, I have gained the operative expertise to perform many techniques in the surgical management of head and neck cancers, including robotic surgery, skull base surgery, sentinel lymph-node techniques, and have a particular interest in the use of microvascular techniques to perform complex head and neck reconstruction. These skills and experiences allow us to offer personalized, effective state-of-the-art treatment plans that optimize both outcome and quality of life.

I have a particular interest in the management of oropharyngeal cancers, and the use of transoral robotic surgery to provide a minimally invasive approaches to these tumors. I also have a strong interest in optimizing the long-term functional outcomes of patients, and tailor reconstructive plans with this in mind. Most importantly, I believe in providing each and every patient my full commitment, time and attention to addressing their head and neck cancer needs. I take great pride in offering compassion and honesty in guiding patients and families through each stage of treatment.
