Frequency of Coach Certifications

Hi, I am interested in pursuing the coach certification. I am wondering how often the certification is offered, and which months they start. Also, I am in SCS. I have not yet mastered my own over-drinking, though I am getting better and better. I have the thought that there is no way that I can become a life coach when I myself haven’t even mastered my issue. I would love feedback on this, and if other coaches are in that same position with their personal goals.
