What is your client turnover rate?
I have some clients that have seen me for years, but most of my clients come and go in less time than that. This may be partly due to me telling them that my main goal as a therapist is for them to not need a therapist. If their pain is under control or gone entirely, they don't come back as often. Some have improved a lot but were unable to continue for financial or other reasons. Others switched to other MTs when it was too difficult to get appointments with me. Some saw me a few times and simply decided they didn't like my approach.
In a large practice, we see so many people that it's hard to keep a good tally of who is coming and going... and many only come 1-2x per year, or only if they are in great pain. Right now I have a new athletic client that has seen me twice and will come back maybe 2-4 more times before she no longer needs my help. She was referred to me by a past client who hasn't seen me in a year, and she in turn will refer others to me in the future when she is back to running without pain. I also have clients that I see only at special events, such as marathons. I'm not sure how they would figure into a tally of client turnover...
Instead of turnover, I look at how many massages our therapists do each pay period and each calendar month, and of those how many are by request. It is possible for an MT to do 25 massages in a pay period, but only have 2 requests. That is a request rate of 8%. Another MT might have 15 massages in the same pay period, but 12 of those clients specifically requested that MT. That is a request rate of 80%. Assuming that both MTs are technically skilled and get good results, what accounts for the difference in their request rates?
