Brendon Burchard, founder of High Performance Academy, has a Certified High Performance Coaching Certification that is the absolute best coaching certification out there.
He basically hands you a world-class 12-Session coaching business in a box, and trains you on all the teachings, and the psychology/thought process behind the coaching practice.
If you're new to coaching this will get you up to speed fast.
If you're a veteran or have some experience w/o certification. You can interweave your own style/practice into the program too.
Not to mention, the community of certified HP coaches is great, people are open with what's working for them and sharing their successes and helping others that are struggling.
This certification can be applied to business coaching & life coaching.
You have to attend High Performance Academy or Purchase the online version of the course as a pre-requisite. Which you should probably do anyways before you invest in the certification to ensure you're aligned with and passionate about the High Performance theories and methodologies.
You can get some free training here to get a taste:
When the registration opens up again for High Performance Academy, you'll get an email. Or you can reach out to me and I can connect you directly with Brendon's Staff to register.
John Maxwell also has a coaching program that if I were looking at coaching programs, I would look into that one as well.
I don't know anything about it, but I know John Maxwell's books are rock-solid and his coaching program probably is too.
Hope this helps!
Good luck to you!
