Select Energy Services Inc., a leading provider of water management and chemical solutions to the U.S. unconventional oil and gas industry, said Jan. 4 that the board of directors has appointed John D. Schmitz as the CEO and president of the company effective January 3, 2021.

Schmitz will continue to serve as chairman of the board of the company. Holli C. Ladhani, the former CEO and president of the company, has departed the company effective January 3, 2021 to pursue other opportunities. As a result of her departure from the company, Ladhani will no longer serve as a director on the board of directors or in any other capacity with Select Energy Services or any of its affiliated entities.

Schmitz has served as chairman of the board since December 31, 2019, and previously served as executive chairman from November 2017 until December 31, 2019. Prior to the company's combination with Rockwater Energy Solutions Inc., Schmitz served as the CEO and chairman from November 2016 through November 2017 and served as the CEO and chairman of Select and predecessor entities since the company was originally founded as Peak Oilfield Services, LLC and began operations in 2007. Under Schmitz’s leadership, Select has experienced significant growth and transformation, both organically and through strategic acquisitions of oilfield services companies and technologies. A lifelong entrepreneur, Schmitz has also founded and developed numerous other successful oil and gas businesses, including Silver Creek Oil & Gas, Complete Production Services and CP Energy.

“It has been my privilege to work with the Select and Rockwater teams over the past ten years. I would like to thank them and wish Select all the best going forward,” Ladhani said.
