Kristin Smith, CFO of Vista Proppants and Logistics LLC, is today’s featured Forty Under 40 honoree.

After a 10-year career with Whitley Penn LLP, Smith joined Vista Proppants and Logistics, , an in-basin provider of frack sand and logistics solutions throughout the Permian Basin, Eagle Ford Shale and Scoop/Stack, in 2016 as its chief accounting officer. Less than a year later, she was named CFO.

Smith’s work ethic was apparent to the Vista team even before she joined the company. When Smith was an audit senior manager with Whitley Penn, one of her clients was Vista. Their close partnership helped Smith to gain knowledge of the oil and gas industry and allowed Vista to recognize her talent and potential.

“Being promoted to CFO was always a goal of mine; however, the opportunity came sooner than I had envisioned,” she said. “I attribute that to a lot of hard work and dedication—and a little bit of luck.”

So far at Vista, Smith has been responsible for the financial oversight of more than $300 million of capital growth and $325 million of capital expansion projects, which include two greenfield sand mines and multiple transload facilities.
