Philosophy of Care 

“My job as a healthcare provider extends beyond providing excellent medical care--it’s to advocate for my patients. I see myself as an educator that helps inform my patients about their diagnosis and treatment options, and I make sure they get the treatment and services they need.

“I truly enjoy getting to know my patients and building a unique relationship with them based on respect, compassion, and empathy. To provide a treatment protocol that is tailored to the specific needs of each patient, it’s imperative that I take the time to listen to them and understand their goals for treatment, while also hearing their concerns. I accompany my patients through the entire course of the evaluation, diagnosis, and treatment process.”
