John quickly became an invaluable partner to our business. He helped our leadership team clarify a 10-year vision, build a proactive hiring roadmap, and commit to the few priorities that matter now.  He moved us from surface-level agreement to deeper strategic decisions—giving us the time, space, and accountability to work on the business, not just in it, and creating real momentum.

John is an incredible listener—thoughtful, compassionate, and genuinely enjoyable to talk to. Using Working Genius, John helped my partner and me understand how to leverage the unique strengths we each bring. He guided us through conversations that highlighted how our different mindsets could lead to frustration and disconnect. Through coaching, we developed structure for difficult conversations and created space to communicate openly in a way that continues to strengthen our partnership.

Working with John over the past two years has brought clarity, alignment, and real momentum to our leadership team. He guided us in building a focused strategic plan, committing to meaningful quarterly priorities, and following through with disciplined execution. Through learning our Working Geniuses, we’ve been able to collaborate more effectively and leverage each other’s strengths. As a result, we’ve had more open and productive dialogue, generated better ideas, and made measurable progress toward our revenue and recruiting goals. John does all of this in a fun and energetic learning environment. If you are considering a highly effective, hands on coach that gets you to think outside of the box, I would highly consider hiring John Tiernan.
