Dr. James W. Williams, a native of Mineola, opened his medical practice in 1946 after his service in World War II. As the number of his patients increased, he built a new state of the art medical facility. The California-style building has a red brick exterior with a wrap around window on one corner. One of its most unique traits was its central heat and air conditioning, a system not often found in the 1950s. The clinic is an impressive example of a building from the 1950s with a contemporary modern architectural style in Mineola. Though the building has passed from owner to owner, it has retained the same purpose of serving the Mineola community.
