Committed to SuccessFounded by Dave and Jan Zerngast in 1991, Zernco Inc. started as a small, family-owned cabinet shop, was incorporated in 1995, and quickly grew into a multi-state commercial general contractor. After transitioning leadership to their daughter, Ashley Thill, Zernco went through another growth phase, increasing its national footprint and client base, until the company was purchased by Zernco veteran Scott Marko in 2019.Our commitment to quality and to our clients' success has helped us build long-lasting relationships and solidified our reputation as one of the nation's premier restaurant and retail construction providers.
