It was always the dream of Dr. Alzeno, Jr. to practice dentistry with his father, whose personal and professional goals he so keenly admired and embraced. Anticipating this, in 1939 his father built a new two-operatory bungalow office across the street at 120 West Front Avenue. Sadly, Dr. Alzeno, Sr. died in 1944 while his son was still in dental school at Northwestern University.
Dr. Alzeno, Jr. reopened the practice upon his graduation in December of 1945. In 1947, an addition was added that provided four operatories and a total of ten rooms.
