Who We Are

About our history

The entrepreneurial spirit of the Donogh’s in the Pacific Northwest started, when Stan Jr. established Donogh Homes, Inc. Stan had been employed in the home building industry for several years, working his way from laborer to superintendent. Following the independent growth in 1962 he opened his own business, Donogh Homes. The company flourished in Factoria, Kirkland, Tacoma, Kent, Bothell, Juanita and Marysville. Soon after growing business into the Florida market, he then opened a commercial division in the mid 1960’s owning a lumber company and a plumbing company during those years.


Continuing the generational legacy in Richland Washington Craig Donogh, son to Stan Jr. started Donogh Enterprises in 1974. After building single family homes there for seven years, Craig, along with his wife and two young sons returned to their roots in Western Washington and began building in Renton, Kent, Covington, Federal Way and Seattle’s Eastside. He continued building and designing hundreds of homes until his death in 2002 at the age 52 after a courageous battle with pancreatic cancer. He is remembered by his family and the Seattle Real Estate community as hardworking, honest and fun loving. He is dearly missed by all who had the privilege to know him.


Craig's two sons Scott, and Ryan worked as laborers for their dad until he passed, and took supervision after his death. To continue the family legacy Ryan started his own company, Donogh Construction, in 1998, which focused on building custom high-end homes. In 2002 Scott joined Ryan and together they built an average of 10 houses a year in the Renton area.


In 2005 Scott opened his own business – Scott Donogh Homes. A year later he joined forces with two business partners and created Northwest Exceptional Homes. Scott has been focusing on SDH’s since 2008, and has continued to build exceptionally beautiful homes.


As we come to the present day, in 2023 Austin Donogh Ryan's son decided to take a step in his own direction, opening Donogh Dynamics an excavation and septic company.  Continuing in his families building legacy, starting from under the ground up.

Centering the work done in His Kingdom, for His kingdom.

All glory to the King of Kings.
