It's never a bad idea to go back to your existing clients and start to reframe gradually how they perceive you and describe you. You are the gateway to their success, but because the commoditization and the velocity of noise, it's easy for that value to be trivialized.
Help them understand your practice and your process, not just that you're a good person. Get them to buy into that panoramically. You'll competitor-proof them through the entire journey and into the next generation and make it easy for them to articulate your value to others.
We continuously work with clients through the Blue Square Method to reframe and maximize existing client relationships. See if you are a fit for Blue Square: https://www.paretosystems.com/blue-square.html
