Philosophy Of Medicine

“I try to treat people like I’d want my family members to be treated. I know a healthcare experience can be overwhelming, so I spend extra time explaining processes to patients and families so they have a good understanding of what’s happening. I am inspired by my dad, who was a surgeon at Altru for 30 years. I saw how dedicated he was, the strong work ethic he possessed, and how important his patients were to him.”
