After working as a carpenter's apprentice during high school and college, Mr. Nystrom became a journeyman carpenter. At 21 he received his real estate license and worked for a title company as an escrow officer. He received his contractor's license at 25, then founded Nystrom Construction Corporation and began a long career as a building contractor and real estate developer.
Mr. Nystrom married Marjorie Adams and they raised their family in one of the homes he built in Sharon Heights. After they divorced, he moved to Foster City.
He enjoyed tennis, hiking, skiing and golfing. He also traveled around the world and pursued his passion for ballroom dancing well into his 80s, say family members.
