Our Story

Diamond Capital Group began with founder Igor Mogilnyy, who started his career in Washington’s roofing industry and built a reputation for exceptional craftsmanship.

As client demand grew, Igor expanded into full residential construction — creating modern, durable homes that quickly attracted attention.

Today, the company has completed 20+ projects and continues to grow as a trusted developer across Washington State.
