Colby Freel


Colby Freel is a designer with a diverse lighting background. In addition to his work in architecture, he has experience in all areas of lighting for entertainment including plays, musicals, corporate design, ballet, contemporary dance, and concerts.

As the craft of design continues to evolve, having a creative background to bring about novel approaches and incorporate new technologies is a powerful benefit to our clients. The principles of storytelling translate across both theater and architecture. As a theater artist, story telling is at the heart of Colby’s design process. Humans experience and make sense of the world as a narrative, and a lighting designers’ task is to craft the stories of homes and public spaces through light. Colby employs his theatrical training and experience to elevate the design and execution of many of eSquared’s commercial and residential projects that incorporate theatrical design approaches, fixtures, and control technologies.

With the advancement of lighting technology, Digital Multiplex (DMX) has become an increasingly prevalent lighting control protocol in the industry. Because of his experience with DMX control design, Colby has aided the eSquared team in implementation of this theatrically based technology. He has taught undergraduate courses and in-office education on DMX and theatrical fixtures as well as developed office practices on design documentation related to DMX. He also uses his theatrical programing experience in many projects that incorporate DMX fixtures.

Colby’s theatrical design credits include the world premier of Post Card American Town and San Diego State University, A Christmas Carol, at Cygnet Theater, and the world premier of Sapience at MOXIE Theater. Colby’s Assistant credits include Kinky Boots, and A Chorus Line at the Benedum Theatre in Pittsburgh, PA.

Colby received his Bachelor of Arts in Theatre: Design and Technical Theater from the Department of Theater and Film at the University of Alaska Fairbanks in May of 2019. In May of 2022 he received his M.F.A. in Lighting Design and Technology at the School of Theater, Television and Film at San Diego State University. Post-graduation, Colby was honored as the 2022 Hemsley Lighting Intern.

Vania Santos

Vania Santos is a former culinary-trained Sous Chef and Executive Chef in Rancho Palos Verdes and Manhattan Beach, who demonstrated her creativity and visual presentation skills with beautiful seasonal dishes in an inviting atmosphere. Vania found her passion and love of Architecture when given the opportunity to travel to different hotels and assist with the opening of new properties by implementing the design features, space planning, and site surveys for new restaurants. The creativity of design developments and functionality of each space, from construction to opening night, motivated her to pursue and achieve an

A.S. in Architecture.

Vania enjoys seeing how light can help accentuate the architectural details as well as how light layers can transform an environment and its mood. Just like salt, light must be carefully placed to the exact amount; if too little, it’s almost unnoticeable, if too much, it’s unpleasant.

Since joining eSquared, she has taken a particular interest in how lighting can affect health. Vania has a passion to help improve the lives of those with neurocognitive disorders, such as Alzheimer’s. Manipulating light to mimic the rising and setting of the sun in interior spaces is very beneficial as it encourages a healthy circadian rhythm which in turn is known to relieve anxiety and overall improve both physical and mental health. 

Vania is developing and evolving our REVIT standards and practices, collaborating with project teams to learn skills and techniques to more seamlessly integrate lighting into the BIM environment.
