About GYC Group

The primary reason homeowners choose GYC over others, and the source of our stellar reputation is the quality, character, knowledge, and experience of our team members. As the primary contact, Mark Koski makes himself available to his clients at any time and has chosen to build a select number of homes annually in order to maintain daily oversight of each home project. GYC Group enjoys an unusually long tenure with the majority of its employees.
