Philosophy of Care
"There's a tremendous value in carefully listening to patients and taking the time to discuss values and preferences that are important to each individual. In situations that may provoke anxiety, I help my patients feel as comfortable as possible and make sure that they feel that they are being listened to.
Through clear communication, I help my patients understand the diagnosis and treatment process in order to empower them when making decisions regarding their health. With each diagnosis, there are multiple treatment options. The right choice depends as much on the patient as it does on the disease process."
