Outside of work, Dr. Emberesh enjoys spending time with her family – she has two adorable children – and loves cooking and baking.

Marcela Popescu, M.D.

The dream to help others when they needed it most and a 2-year-old Hungarian boy with acute leukemia inspired Dr. Marcela Popescu to become a doctor.

Today, she helps deliver protocol-related care to pediatric patients in our area and in collaboration with community physicians, to ensure timely referral and diagnosis and appropriate therapy for these children.
