David R. Wasserman was born on December 3, 1944 in Newark, New Jersey. In 1966 he graduated from Rutgers University with his bachelors in Zoology. In 1970 he received his Doctor of Medicine in Dentistry from Tufts University School of Dental Medicine. Upon graduation he served two years of active duty as a captain in the United States Air Force Dental Corps at Nellis Air Force Base.
In 1971, Wasserman became the second Jewish dentist in Las Vegas after many years of the Dental Board blocking Jewish dentists. Wasserman has received many accolades for his work in dentistry including being elected to the Academy of General Dentistry's prestigious Fellowship Award in 1983. His entrepreneurial spirit occurred during the outbreak of HIV-Aids in the 1980s when Dr. Wasserman became aware of discrepancies of infection control in dentistry. He invented the Sani-Tip, a disposable air/water syringe that is changed between patients to lessen the worry of contagions. Upon the founding of Congregation Ner Tamid, Wasserman served as the vice president from 1974-1976 and as president on two occasions. He is also active in the Jewish Federation of Las Vegas and served on the board of directors for ten years. He is married to Juanita Davis-Wasserman.
