Memorial Hermann Katy Hospital
The hospital was established in the 1980s. In 1999 Memorial Hermann acquired the hospital.
In 1999 Memorial Hermann Hospital purchased a plot of land from HCA Inc. and established the Katy Hospital there. The hospital, licensed for 118 beds, was on Pin Oak Road in Katy, west of Katy Mills Mall. The hospital there had 100,000 square feet (9,300 m2) of space. In 2005 the hospital system put the ex-HCA land and the campus on it for sale. A daylong move to the new $98 million facility occurred on Saturday December 9, 2006. The current hospital has about 300,000 square feet (28,000 m2) of space.
In October 2013 the hospital held a groundbreaking for a 100,000-square-foot (9,300 m2) patient tower. Construction of the facility, with an estimated cost of $70 million begin in early 2014, and is scheduled to begin accommodating patients from January 2016. It will increase the hospital's bed count from 144 to fewer than 200. The new tower will house an extended ICU and IMU, new laboratory facilities, and will include additional cardiac catheterization lab space amongst other new facilities.
Professional building 2 was constructed in 2014/15 and was completed in the fall of 2015.
