One after the other, Nakhleh Zarzar’s three sons followed in his footsteps by choosing a career in psychiatry and joining the family practice. Their father’s passion for his work, the sons say, inspired them.

Nakhleh Zarzar, M.D., is now retired, but during the late 1990s, he practiced psychiatry with sons Michael, David, and Nicholas in Raleigh, N.C.

After graduating from medical school in Beirut, Lebanon, Zarzar completed his psychiatry residency at the University of North Carolina School of Medicine in Chapel Hill in the late 1950s.

In the following years, Zarzar served as medical director of Dorothea Dix and John Umstead hospitals. From 1973 to 1977, he served as North Carolina’s director of mental health.

Zarzar entered private practice in 1977, but it wasn’t until 1990 that the eldest of his three sons, Michael, joined the practice. Nicholas joined a few years later, and the youngest, David, joined in 1997.

Michael and his brothers admit to being influenced by a parent who loved his work.

The Zarzar brothers feel fortunate to have been joined by a skilled team of professionals over the years, enabling them to continue their father's tradition.
