The headquarters of Davis Vision in Plainview, New York, is moving to San Antonio, Texas, the company has announced. The move affects only the corporate and administration offices – and about 100 employees – as sales and client management, manufacturing, customer service, and the IT center in the Plainview area will stay put. Davis Vision said the move will put its headquarters closer to the retail and distribution operations of HVHC, its parent company. The move should be completely by the end of the first quarter next year.
