Douglas Henry Obenshain

Douglas H. Obenshain, age 67, of Carlsbad, California, passed away on February 3, 2026, in La Jolla, California.

Doug was born on December 20, 1958, in Toledo, Ohio. He was born to Velma and George Obenshain.  He grew up in Perrysburg, Ohio. He attended Miami University of Ohio, where he majored in accounting. In 1985, he moved from Ohio to San Diego, a place that would become home for the rest of his life.

Doug spent many years at Ernst & Young, where he was instrumental in building the firm’s life sciences practice until his “retirement” in 2009. He then went on to a highly successful second chapter as a partner at Lockton. In recognition of his service and leadership, Doug was honored as 2017 Director of the Year (Nonprofit). At both firms, Doug was a treasured mentor, trusted advisor, and loyal friend to employees, clients, business partners, and the broader San Diego community. He deeply believed in paying it forward and was passionate about investing in others and helping them succeed.

Doug was kind, steady, and deeply devoted to those he loved. He often described himself as a “simple and practical guy” who valued common sense, yet he was also full of warmth and possessed a truly memorable sense of humor. He had an easy way of putting people at ease and made others feel seen, valued, and understood. Doug found great joy in planning family trips and creating meaningful life experiences for his family.

Doug is survived by his wife, Milley Mai; his three sons, Nate, Alex, and Apollo; his daughter, Andromeda; his grandchildren, Nora and Henry; his brother, Steve; Megan, who was like an aunt to the children and a pillar in their home; his mother- and father-in-law.

An open house viewing will be held on February 20 from 10:00 a.m. to 1:00 p.m. at the Seaside Center for Spiritual Living in Cardiff. A celebration of life will follow on February 27 from 2:00 p.m. to 6:00 p.m. at The Fairbanks Ranch Country Club. All who knew and loved Doug are welcome to attend the viewing and celebration of life.
