Laurence B. Tree II (“Larry”) is a proven entrepreneur and strategic leader who has built international businesses and brands from initial funding through to successful business process and technology development. Larry’s passion is to build great teams of people working together with the skill and persistence to drill into initial business plans and collaborate to execute strategies and tactics focused on excellence.

Before joining Proteum Energy, Larry was the President and founder of Laron, Incorporated, a 40-year leader in heavy industry service solutions focused on power generation, mining, oil and gas, heavy manufacturing, transportation, and construction industries. Laron was acquired in January 2020 by Ohio Transmission Corporation, a GenStar company.

In 1984, Larry founded EMS (now Sulzer EMS). EMS became the largest independent service company for power generation, mining, and basic industries in the Western U.S., reaching #24 on Inc. Magazine’s fastest-growing companies in America.

Larry successfully completed the sale of EMS to a public U.K., PLC and global leader in heavy industry services. He served five years on the international board of directors. EMS is now a business unit of Sulzer Turbo Services based in Winterthur, Switzerland.

Larry’s entrepreneurial successes lead him to be nominated Arizona Entrepreneur of the year and the Who’s Who of Executives in America.

Larry also has a varied entrepreneurial and philanthropic background. He co-founded and co-created the world’s leading integrative medicine web portal (www.DrWeil.com) and product licensing company. This creation was at the request of Dr. Andrew Weil, a renowned integrative medicine physician, and author. Mr. Tree developed the initial business plan and secured funding, co-creating an international web and licensing business. The philanthropic goals were achieved and millions of dollars of profits were raised; all focused on funding Dr. Weil’s non-profit, Weil Foundation. The Weil Foundation significantly contributed to the Program of Integrative Medicine at the University, which is now the very successful Arizona Center for Integrative Medicine (www.AZCIM.com), a Center of Excellence within the University of Arizona.
