Dr. Lawrence Garner

Dr. Lawrence Garner is a villain appearing in three episodes of the television series Smallville. He was portrayed by Martin Cummins.

Dr. Garner is the founder and head of the Summerholt Neurological Institute, a Metropolis-based research facility specializing in neurology. When Ryan James, a young boy with telepathic abilities, began experiencing headaches and nosebleeds, Garner offered to help him. He took Ryan and kept him prisoner at Summerholt, where he experimented on the boy.

In "Ryan," Dr. Garner has Ryan tell him what image he's looking at and even presses him on despite Ryan clearly suffering a headache. When Ryan tricks him into leaving the room, Garner tracks Ryan to a room where Ryan manages to call his friend Clark Kent and beg for his help. Clark, with the help of his friend Chloe Sullivan, traces the phone call to Summerholt. When his parents are unable to get in contact with the facility, Clark heads to Summerholt himself and demands to see Ryan.
