Hemdale Recovery Center is an addiction rehabilitation center. Sherlock Holmes attended Hemdale after drug use in London and NYC. Staff include Dr. Stephen Carrow, Dr. Ryan, Dr. Caruso and Edson, the groundskeeper. Its first appearance is in the Season One episode "One Way to Get Off".
As Joan Watson first visits The Brownstone to meet her new client Holmes, she's called and told Holmes broke out on his last day of rehab. Holmes tells Watson he broke out due to boredom and that Hemdale should be thankful as he exposed their security flaws. Later, Holmes mentions that the patients would often watch baseball games. ("Pilot") As Holmes blackmails Mike McGee into providing an investigative file in exchange for not disclosing his meth use to Captain Gregson and Detective Bell, he recommends Hemdale to him and says there's a pool at the facility. ("While You Were Sleeping") Hemdale is first seen when Watson visits to find out more about Holmes. She questions Dr. Stephen Carrow but learns little about Holmes.
