I would not be comfortable with a T much younger than me (but I'm getting up there). I prefer a therapist with similar life experience: marriage (can be divorced), raised kids (not just young ones - I'm WAY past the toddler years), aging parents, the basic life experience that comes with age. A young, inexperienced therapist would probably turn me off. I've found my older, more settled, experienced therapists to be solidly professional, highly skilled, able to handle a crisis without fumbling around, and life-long learners not at all set in their ways. On the contrary, because of their years of experience, they had a bigger toolbelt to work with and were able to discern what approach to take at different times, unlike lesser experienced therapists who either are stuck on one approach due to lack of experience or still experimenting clumsily with whatever latest technique they just learned in some workshop somewhere.
