One on one coaching

Hi there! I am loving scholars so far. I am trying to focus on my effectiveness at work and think it could be helpful for me to get some more one on one coaching. My ten minute session last month was very helpful and I think I could benefit from more frequent and longer sessions. I was wondering how the individual one on one session packages work. Do we have any choice in the coach we work with? Are there any coaches that specialize in executive coaching?
