Triage Staffing Headquarters*

Omaha, NE | Corporate


A four-floor corporate headquarters that required a cohesive lighting strategy across open offices, collaboration zones, and executive spaces. Each floor is anchored by a 100+ foot long recessed asymmetric linear fixture running along the core wall. This dramatic, continuous line of light serves as both a wayfinding element and an architectural statement, unifying the open floor plates with a bold, clean gesture.

Bellevue Public Library*

Bellevue, NE | Civic


A creative adaptive reuse — converting a former data center into a vibrant public library with an inviting environment for reading, community gathering, and children's programming. The children's area is particularly noteworthy: playful yet carefully coordinated luminaires — rings, disks, and accent elements — with finishes selected to match the interior design accent colors, creating a space that feels joyful and intentional.

Dormie Club Clubhouse*

Pinehurst, NC | Hospitality

A boutique golf clubhouse where the architecture and materiality are the stars — and the lighting was designed to keep it that way. Extensive concealment of luminaires and multiple layers of light highlight the rich materials and architectural details without visible hardware competing for attention.

University of Nebraska Tom Osborne Legacy Complex*

Lincoln, NE | Education


The three story, 300,000 square foot, $150M renovation and addition of the Husker football facilities included advanced lighting aspects throughout the project. Color-changing lighting with animations and dynamic effects were used in the locker room, team meeting room, and pool areas. A plethora of accent lighting applications were incorporated throughout the entirety of the project. Tunable white controls were implemented in the head coach’s suite.


With the complex design components, multiple involved parties, high profile, and accelerated schedule, effective lighting commissioning was critical to keep the project on track. With the lighting controls programmer flying in from out of town for each programming visit, it was imperative that he had the required information on time to keep moving forward at an efficient pace. For this project, the lighting commissioning consisted of the following tasks:


  • Design review of the construction documents to identify any information gaps needing to be resolved
  • Confirming the installation conformed to the owner’s requirements
  • Functional testing of the lighting controls
  • Confirming the desired functionality for each scene and zone for spaces with multi-scene programming
  • Acting as the coordinating point of contact between the general contractor, electrical contractor, the owner’s internal team, the third party project manager, electrical engineer, and the lighting controls programmer
  • Contributing to the resolution of various issues that arose during construction

Grief's Journey - A Collective for Hope*

Omaha, NE | Healthcare (Unbuilt)


The 8,000 square foot facility was intended to serve as a counseling center specifically serving youth affected by trauma. Areas for children of all ages were planned for.


In the corridors, artwork that was created by the children as a part of their healing process was to be displayed on the walls in a prominent location. In this portion of the corridor, exposed wooden structural members created a tall and open space.

Cove lighting that was concealed from the view of passersby in the corridor was utilized to uplight the wooden structural members and ceiling to emphasize the verticality of the space. Spotlight type luminaires were provided on top of the ledge connecting to the wooden structural members on one side of the corridor. These spotlights aimed down and across to the other side of the corridor to highlight the artwork created by the children.


These spotlights were mounted on vertical arms to ensure the beam of light would adequately clear the corner of the ledge they were mounted on. The optic of the luminaire and spacing between luminaires were closely studied to ensure the artwork was evenly illuminated without hot spots, while also avoiding washing the entire wall with light.


Note: This project was fully designed but not constructed.


Scope: Lighting design, controls design

Key Feature: Art-focused lighting concept designed to support a therapeutic, calming environment

Wisner-Pilger Early Learning Center*

Wisner, NE | Education


The 10,000 square foot addition to the existing high school created multiple opportunities for the lighting to enhance the occupants’ experience. On the exterior of the building, a three-sided recessed asymmetric linear pattern luminaire totaling approximately 50’ in length wraps around the overhang over the main vestibule and walkway, grazing the vertical perforated metal panel surface to create a silhouetted view of the walkway behind it.


In the interior of the building, recessed asymmetric linear luminaires highlight the display areas on the walls of the corridors to showcase students’ artwork. Careful study was done to ensure the distribution of the asymmetric luminaire would evenly light the display area without leaving a hot spot at the top. This additional layer of light on the vertical surface also greatly increased the perceived brightness of the space.


Linear direct/indirect luminaires bring attention to the glulam ceilings via soft diffuse light while also adding reflected ambient light for uniform illumination of the walking path.


Scope: Lighting design, controls design
Key Feature: Corridor display area for student artwork, exterior facade wraparound linear luminaire
