GYC Group — Company History

The story of GYC Group, from its founding by Garnett Y. Clark, Jr. to today's operations under Mark Koski's leadership.

Origins

GYC Group (originally GYC Builders) was founded by Garnett Y. Clark, Jr., a second-generation custom home builder who established the company in 1981. Clark brought a deep lineage of construction knowledge — his family had been building in Maryland for generations, with a strong presence in Howard County and the Columbia, Maryland area.

Clark was known as a prominent developer in Howard County, where Columbia's planned community was transforming the Maryland landscape. His experience bridging traditional craftsmanship with the demands of a growing suburban market shaped the DNA of what GYC would become.

TODO: Expand this section with specific projects Garnett Clark was known for, his development work in Howard County/Columbia, and the early years of the company. This is critical institutional knowledge that should be captured from Mark Koski and anyone else who worked with Clark.

The Name

GYC stands for Garnett Yelverton Clark — the company carries the founder's full name as its identity. Even as the company has evolved, the name serves as a reminder of the craftsmanship tradition and standards that Clark established.

Evolution to GYC Group

The company transitioned from GYC Builders to GYC Group Ltd., reflecting an expansion of capabilities beyond home building into a broader construction management operation encompassing:

  • Custom home construction
  • Major remodeling and renovations
  • Additions
  • Land development management

Leadership Transition

Mark Koski mastered his craft under the expert tutelage of Garnett Y. Clark, Jr. This apprenticeship-style knowledge transfer — learning the business from the inside out under the founder's guidance — is a defining characteristic of GYC's culture. Mark has since earned his own distinguished reputation for the construction of some of the finest custom residences in the area.

Today, as President and primary point of contact, Mark personally oversees each project — intentionally limiting the number of homes built each year to ensure hands-on involvement at every stage. He leads GYC Group from its headquarters at 611 Nursery Road, Westminster, MD 21157.

TODO: Capture Mark Koski's account of the transition — when it happened, what changed, what stayed the same. This is the most important oral history to preserve.
