Two-plus decades in cleantech, spanning development, finance, and advisory work across the US, Hawaii, and Southeast Asia. I founded a Hawaii solar company that SunEdison acquired in 2007 — a path that started, improbably, with a 2002 cold call from Jigar Shah at BP Solar looking for a way into the Hawaii market. That call became a lasting friendship and set the trajectory for everything since.

I've co-taught the Solar Executive MBA on HeatSpring since 2013, working with 500+ students across the globe. 

In 2026, I expanded the curriculum into a deeper program on data-room diligence, contracts, and project finance — designed for developers, investors, and operators who need to move from concept to closed deal.

The course includes the contract templates and a working financial model, so students leave with the tools to run their own deals — not just an understanding of how others run theirs.

Bain & Co., TPG, MHR Fund Management, Halcyon Capital Management, Moab Partners, Glenview Capital Management, Walmart, Hawaiian Telcom, Dividend Finance, REC Solar, the US Department of Energy, the US Department of Defense, the State of Hawaii, pension funds, and a range of Wall Street and Main Street firms.

Expert witness, executive recruiter, business consultant, energy asset advisor, startup mentor, solar developer, owner's representative, and capital raiser for solar projects and portfolios.

I've supported deal flow between buyers and sellers across the full capital stack — sponsor equity, tax equity, preferred equity, construction debt, term debt, and mezzanine — with both local and national lenders. Structures include the traditional partnership flip, the hybrid tax flip, and sale-leaseback, at both the single-project and portfolio level in the nine figure zone. I've also helped operating companies exit their asset portfolios to buyers looking to grow AUM.

My work spans across the US from coast to coast. A brief stint in South America with extended time in Southeast Asia —  in Malaysia (Singapore and Kuala Lumpur), Indonesia, Cambodia, Vietnam, and Laos on a one-year visa. Culture and curiosity are equalizers. Based in SoCal and Hawaii; working globally.
