Driven by results, built on trust.

I'm Griffin Mallas, founder of Group Practice Builders. I help therapy practice owners build scalable, profitable group practices — and prepare for what comes next, whether that's continued growth or a strategic exit.

My work is direct and focused. I don't do generic business coaching. Every engagement is built around your specific practice, your team, and your goals.
