My T, I'm guessing, is in her early 30's. She's never said, but that's my speculation based on a few factors.
I like having a T that young, because it's easier to connect. My old T was probably in his 60's, so things were less connecting and less comfortable. I don't think age really affects how well or how effectively a person practices; however, I feel like it can effect how a client connects with him or her.
