PND's Founders

Print

Dennis Nottingham, P.E., P.L.S.

After graduating from Montana State University in 1960, Dennis worked for two years with the Montana Highway Department Bridge Section and 10 years with the Alaska Highway Department Bridge Section, producing designs for several large bridges. His early work focused on the Trans-Alaska Pipeline System projects assisting with module bridges and road design. Marine engineering became an important company expertise at PND, and many cruise ship docks were designed for cities such as Seattle, Ketchikan, Juneau, Haines, and Skagway.

Dennis served as president of PND from its founding in 1979 until his retirement in 2010. During his more than 30 years as president, Dennis recognized the need for research and development in the bridge, arctic, and marine areas, as well as the need to provide leadership in a state with limited long-term infrastructure planning. His significant research on arctic foundations, ice forces, bridges, piles, wave barriers, retaining walls, and ports resulted in significant engineering feats. He is credited with analysis of the first vehicle cable-stayed bridge in the United States, completed in 1971 in Sitka.

During his career, Dennis received nine U.S. patents and was inducted into the Alaska Innovators Hall of Fame. His accolades also include the Associated General Contractors of Alaska Hard Hat Award, the NOVA Award for the OPEN CELL SHEET PILE™ design, 15 Lincoln Arc Welding Foundation awards, and several bridge design awards from the American Institute of Steel Construction and National Steel Bridge Alliance, respectively.

Brent Drage, P.E.

Brent joined the firm in 1981, and it was renamed Peratrovich, Nottingham & Drage. Sadly, he passed away in 1988. Brent led several major projects such as Susitna Dam, Bradley Lake Dam, and St. George Breakwater. He was also instrumental in winning the Red Dog Road project, which later resulted in PND obtaining several other Arctic projects in Alaska, Russia, and Canada. He is remembered as a skilled engineer and a pioneer in the field.

Roy Peratrovich, Jr., P.E.

Roy began his engineering career in 1957 as a bridge engineer for the City of Seattle before moving to Juneau, Alaska. A Tlingit Indian born in Klawock, Roy was the first Alaska Native to be licensed as a professional engineer in the state. He was one of the original founders of PND.

Roy has been retired from PND since 1999, and he now lives in the Pacific Northwest where he creates bronze sculptures celebrating his heritage in the Raven Clan, known as the Lukaax-Adi Clan (Ravenworks Art Studio). Roy has also written and illustrated a young adult book titled Little Whale. Additionally, some of Roy's beautifully crafted sculptures and works of art are on public display throughout Anchorage and Juneau.

Roy's mother, Elizabeth Wanamaker Peratrovich, was an Alaska Native civil rights activist. She had a strong influence in the Anti-Discrimination Act of 1945 passed by Alaska's Territorial Legislature. Feb. 16 is an Alaskan state holiday in her honor.
