A father-and-son industrial real estate team in the Kent Valley
Mike Hemphill has represented corporate occupiers in the Puget Sound for more than 30 years. Ben Hemphill joined him at The Andover Company after a career closing high-stakes deals in medical device sales. Together they give clients something rare in brokerage: a principal’s experience and a hungry operator’s attention on every assignment.
How we work
We represent one side of every deal and say so. When we are on the tenant’s side, we are not also chasing the landlord’s listing. We start with your business, model the options on a total-cost basis, create real competition among landlords or buyers, and negotiate the document, not just the rate.
