A good therapist to me:
cares about me in a genuine way
has a sense of urgency about relieving any pain I'm in
does what they say they are going to do
has humility
has a sense of humor and hope
will explain the process without dumbing it down
has patience
has practical advice when needed
has firm but flexible boundaries

A bad therapist:
is distant, cold, excessively silent
doesn't care if I leave the office in pain
forgets about me after our 50 min is up
is directionless
is forgetful of vital facts
is dismissive or blaming
is suspicious of what I say
dislikes me openly
is arrogant
talks down to me
excessively rigid boundaries
doesn't care about me or the outcome of therapy
