Dear students: Service doesn't just look good on your resume. It builds your character. 62 studies, 11k students: service learning enhances leadership skills, civic engagement, self-confidence, motivation, and grades. Community service should be part of every child's education.

Six years ago I was barely getting interview invitations for a diagnostic radiology residency position. Yesterday I was elected chief resident at @Stanford_IR . Hard work and dedication always pays off.

@MasNakhaei @UCSDImaging @TulaneRadiology Congrats! Well deserved

Screaming at employees doesn't make you a tough boss. It makes you an asshole. Great leaders are demanding, not demeaning. They set high expectations and create accountability without abuse. Yelling is unprofessional. Treating people with dignity is not optional—it's required.

Done with residency! Amazing experience at @TulaneRadiology. Grateful for all the mentors/friends. Time for the next chapter at @Stanford_IR. #IamIR #IR #radiology #radres

@RaulChF Segundo emocionado aquí

Surgeons don't restrict themselves to a segment or 2, why should we? Isn't it the FLR that matters?
