What is the name of Betty Draper's psychiatrist?

What is the name of Betty Draper’s psychiatrist? The answer is Dr. Wayne, specifically Dr. Arnold Wayne. He treats Betty during Mad Men’s first season after she develops episodes in which her hands unexpectedly become numb, particularly in the aftermath of her mother’s death.

Dr. Wayne’s role is complicated by the era’s limited expectations of privacy and by Don Draper’s influence. Without Betty’s full knowledge, the psychiatrist communicates with Don about her sessions. Betty eventually realizes what is happening and uses the arrangement strategically, telling Dr. Wayne about her anger over Don’s infidelity because she knows the information will reach her husband.

Dr. Arnold Wayne is played by Andy Umberger. He is different from Dr. Edna Keener, the child psychiatrist who sees Sally and also becomes a temporary outlet for Betty’s own concerns. Dr. Rosen is another Mad Men doctor, but he is connected to Megan’s father and later to Don’s social circle, not Betty’s primary psychiatrist.
