What is your philosphy on Emergency Medicine?

"The appeal of Emergency medicine for many is the opportunity to provide skilled interventions for those with urgent illness or injury, however I consider equally important our responsibility to emotionally support and educate our patients, families, and communities. The ease of access to the ED affords us the chance to address public health issues as well as ensuring our patients have the resources and knowledge to autonomously address their health conditions."

What is your philosphy on patient care? 

"Honoring human dignity and meeting people where they are is the difference between standard of care and excellent care."

What is your philosophy on patient care?

"Physicians possess a unique body of knowledge and skills that may be used for the benefit of patient care. As patients put their trust in us, it is important that we understand their needs. Patients want to be able to trust the competence and efficacy of their caregivers as well as to be able to negotiate the healthcare system effectively. They also want to be treated with dignity and respect. The keys to meeting these expectations are education and inclusion. We must make efforts to ensure that those under our care fully understand the processes that affect them. Equally important, is including them as partners in all aspects of their care. In this way, we can enhance the patient experience and create a mutually beneficial relationship where both patient and physician achieve their care goals."
