If I were you, I might try to shoot for somebody middle-aged. There is the risk of retirement with an older T, but there is also risk associated with inexperience with a younger T. You want somebody who has the experience to know themselves and whether they can handle working with intense attachment stuff, and you want somebody with the wisdom to know that they shouldn't make promises they can't keep. I think some of the biggest, most disruptive damage happens when the client gets in too deep with a therapist who doesn't have the skills to keep them both safe.
