Funeral services for 30-year-old Samuel Waisbren were held in his hometown of Fox Point, Wisconsin, just outside of Milwaukee.
Waisbren was killed Thursday while getting off the elevator in his building's lobby in Kips Bay.
Firefighters say the elevator suddenly dropped and trapped him between the car and the wall.
The Department of Buildings is investigating what caused the elevator to malfunction.
Waisbren's father said he spent six years working for a tech/finance company called CB Insights doing sales.
