Which is right for you? Depends on your situation, and to some degree on your budget.
The main difference spins around the idea that as a coach I help you come to your own decisions and insights about a situation or goal. As a consultant I may also ad levels of advise and my own personal experiences to the mix. Both are valuable outside assistance but coaching will tend to become more personal in it's scope while consulting may or may not touch on personal issues.
Of course there is more to it. Call or email me to discuss.
