Our Team


Karl Holland - Owner

Karl has built Holland Construction based upon the core values of a strong work ethic, a sense of urgency, a phenomenal client experience, the strong fiscal health of the company, and a sense of fairness for all involved.

Karl was exposed to this industry at a young age. He spent his teen summers and weekends working in his father's construction/remodeling business. After attending the University of Arizona Karl decided to continue working in the construction business and in 1986 formed his own company in Tucson. 

Having all but a few trades “in house”, keeps Holland Construction in control of the design and construction timeline. This cuts weeks and sometimes months off from start to completion and also assures that the client experiences the Holland Construction team's uncommon level of friendliness, professionalism, and competence.

Diane Stuart - Designer/Project Manager

Diane joined Holland Construction in 2017 bringing 20+ years of design and remodel construction experience in both California and Arizona. Her projects have included residences, retail spaces, and office planning, with an emphasis on kitchen and bathroom remodels. 

Diane enjoys collaborating with home and business owners. She offers clients a keen sense of design and functionality with an emphasis on 3-dimensional modeling so they can envision their projects from the outset. 

Diane is proud to be working with Holland Construction's team of highly-skilled craftsmen whose attention to quality and detail transforms our clients' vision into renewed living/work spaces.
