Established in 1968, HDR|Daniel Frankfurt presently maintains a full and diverse staff consisting of three working principals and a strong number of engineering, architectural and construction professionals. Approximately half of the engineering and architectural staff is professionally registered in New York State.

In addition to our reservoir of civil and structural engineers, architectural group, and construction personnel, HDR|Daniel Frankfurt has a number of specialized staff such as Traffic Engineers, Transportation Planners, and Electrical Engineers. These specialists allow the firm to perform many functions in-house that would otherwise rely upon subconsultant firms.
