Firm Profile

Hefferan Partnership Lighting Design is focused on providing clients with expert service and advice regarding the design direction, equipment selection, and final focus of lighting systems for museums, permanent and special exhibitions, private galleries, and high-end residences.

For 25 years, founding partners Krystal Mackey and Steven Hefferan have specialized in creating luminous environments suitable for the display and engaging viewing of light sensitive collections at many of the country’s premier art, science and history museums.
