I build companies, and I help the people who run them.

Thirty years in science and technology. Twenty-four of them building med tech products and the teams behind them. The last six as an advisor and investor in Auckland and on the Gold Coast. Right now that means COO at UV Sentry, strategic advisor to Dennisson Technologies, and coach to leaders in high-impact, high-risk situations through Captaincy, with a book in between.

I like building companies. I also like what happens to people when they're given a real job and backed to do it. That's why I do both, the commercial work and the coaching. They aren't two careers. They're the same thing.
