Our Team


Jon Greiner is the founder and CEO of Basin Safety, owner of FlowCore Systems, a fluid system manufacturing and service provider and has started many small businesses in the area in both oil & gas and other sectors. Greiner’s industry experience with Schlumberger and smaller E&P companies jettisoned his career in the Oil & Gas industry and shaped his insights into how field level personnel and management teams can more effectively work together to achieve both higher safety standards and increased profitability.

He believes in getting more out of your team, your company and your career through effective communication rooted in respect and accountability.
