Teen Wolf Wiki

Dr. Alan Deaton is a recurring character in Teen Wolf and is played Seth Gilliam.

He is a veterinarian at Beacon Hills Animal Clinic where he is Scott McCall's boss and becomes a mentor to Scott and his friends on all things supernatural.

He's the older brother of Ms. Morrell who is also a Druid.


He is the former Druid Emissary to The Hale Family and had a very close bond with Talia Hale. His reputation stretched far enough that The Argent Family knew of him. However, only Talia and eventually Laura Hale knew of his existence within the pack.

Some time before her death, he made a promise to Talia that he would look after Derek. When Talia and most of her family died in a fire, he "retired" from his supernatural duties.

When Scott was bit by Peter, he decided to help him adjust to his new life without revealing too much about his past and subsequently brought himself out of retirement. However, he came clean when Stiles Stilinski figured who he was when a Darach began committing murders. Since then, he has been assisting Scott's pack in their supernatural investigations.
