Certified communication style coach obsessed with helping leaders break barriers

Maven's Terms and Privacy Policy.

With degrees from top institutions and a track record of professional success in competitive and challenging environments, I was promoted to C-level in my 30s. But I was struggling to get consistent results from all of my team members. If I was recognized by others as being smart and accomplished, then why wouldn't people just do what I wanted all the time?

It takes way more than credentials to earn trust. More than anything, it requires understanding how you appear to others in your interpersonal communications.

I relied on this model as a VP, CSO, and COO in rapidly growing companies.

I have seen the most seasoned executives have "aha moments" when they see how this tool empowers them and their teams to break communication barriers and improve outcomes.
