I found my therapists got it mostly right.

Consistency
Reliability
Responsiveness
Skill
Communication
Support

I honestly can't think of any particular faults or mistakes of any real consequence. Actually, I can't remember any mistakes specifically at all which speaks to the fact that they were relatively minor, easily resolved, and of no lasting effect on our work together. We worked together long-term, and when the time came, we parted ways and moved on for a variety of reasons.
