A massive Mercer Island waterfront estate has a new owner from Texas.
Rodney Lewis, the San Antonio-based CEO and founder of the thriving Lewis Energy Group, recently paid $28 million for the mansion situated in the Shorewood neighborhood, according to the Seattle Times. Lewis’s co-buyer in the June 30 off-market transaction is listed as Hanne Maureen Zak. The assessed value of the property is $15.2 million.
The duo’s property features two homes and covers a total of 12,840 square feet, according to The Puget Sound Business Journal.
The Reporter reached out to the Lewis Energy Group — a leading natural gas and oil company founded more than 40 years ago — Zak and local realtors for details on the transaction and estate, but didn’t receive responses at press time.
Forbes notes that Lewis, 71 — who was listed on the media company’s 2018 billionaires list — owns America’s biggest fleet of air-worthy World War II fighter planes.
He received a bachelor of arts degree in science from Texas A&M University, and in the early ’80s “began drilling his own wells in tight gas sands and began acquiring the pipelines and oilfield equipment necessary to control his own destiny,” reads his company’s website.
