I found this picture of the old Sugar Land clinic. I don't know exactly when it opened, but it must have been sometime in the late 1940s. It sat on the northeast corner of Highway-90A & Ulrich Street. Before it opened Sugar Land's doctors had a small 'clinic' in the old drug store that sat next to the administrative office of Imperial Sugar Company in front of the refinery. Here's a photo of the 'new' clinic.
