Which of these scenarios would you prefer as a customer?
You go to a holistic health practitioner, let's say a nutritionist, from whom you seek help for a skin condition. She tells you to eat lots of this and stop eating that. It doesn't really work, so you decide to visit a chiropractor. He tells you its all due to a kink in your neck and once he fixes that (after a mere seven visits) you won't have the skin problem. It doesn't help. So then you seek an herbalist, who says take this herb and rub this salve on your arms. This works!
You look for someone who can help you with your skin problem. You see an ad in the new age journal that says "Holistic remedies for skin problems - call 999-999-9999."
You call and make an appointment. You find out that this person has trained as a nutritionist, bodyworker, herbalist and yoga teacher. She has found out the best ways to holistically treat skin problems. She sees people with skin problems all day long, and she has a passion for solving skin problems, since she once had a disfiguring skin problem that she healed herself with holistic means. She is able to help you with a set of nine visits.
So, which one would you prefer? Although it is the same number of visits and probably the same cost for both scenarios, the second one is preferable because you have someone who really understands your problem.
The feeling I sometimes get with holistic practitioners who are not customer-oriented (like Scenario B) is that they are always guessing. "I'm going to guess that my bodywork/energy/nutrition/exercise is going to help your condition x." That does not strike confidence in me.
Holistic health practitioners, listen up! Re-orient your practice towards a specific health issue that you can solve for your clients. We'll appreciate it very much!
